Title: Whither the future: Thorn's derailleur vs Rohloff bikes
Post by: leftpoole on December 03, 2015, 09:44:50 am
[Topic moved intact from a discussion in the Bikes For Sale board about a used Thorn exxp offered by SJS Cycles. John's opinion is worthwhile, but more suited to its own topic, since it will surely spawn replies that don't apply to the bike for sale. -- Best, Dan.]

Description from the original brochure... http://web.archive.org/web/20070305193447/http://www.thorncycles.co.uk/thornpdf/ThornRohloffeXpBroHiRes.pdf
Quote
After many years’ prototyping, by Andy and Fiona, the definitive eXXp (E, double X, P) has finally arrived!

It has the same frame tubes as theRohloff eXp R but it uses differentstays, which are cranked to allow the
fitting of up to 2.4”knobbly tyres...Rohloff equipped 26 inch wheel - Expedition touring cycles with huge mud clearances, if desired!

The eXXp is designed for Adventure Touring holidays (long distances, with heavy loads over severe terrain).

The eXXp is suspension specific, i.e. it is designed for a suspension fork (Magura Odur) with 100mm travel.

It has the cable runs for an EX hub, reinforcing tubular gussets at the back, 6mm carrier bosses and, whilst at present there are no discs available (which we would recommend) for Adventure Touring, we have “future proofed” the frame by providing ISO disc mounts and carefully considering the potential for neat routing of a hydraulic line... we have also chosen to fit V brake bosses with removable studs, should a disc be used instead.

An additional, extra-long, rigid, twin plate crown fork (to compensate for the suspension specific geometry) can be supplied to allow the eXXp to be suitable for economical day to day use or for a really epic journey, when servicing suspension would be impractical. Compared to the Rohloff eXp, the eXXp has slightly longer chainstays, because with a suspension fork, most of the weight has to be carried on the back of the bike and bigger bags need longer chainstays to help keep the weight within the bike’s wheelbase.

The eXXp is both huge and ruggedly good looking... like a Clydesdale... our bikes (Andy and Fiona’s) are called “Bertha” and “Hector.” These magnificent beasts have just returned from a long holiday in Patagonia, where they performed faultlessly and both flattered and cosseted their owners, by covering the extremely demanding terrain in impeccable style, whilst carrying full camping kit
and up to 10 days shopping!

The eXXp is, as you might expect, the most expensive of our solo bikes. It is available in just 10 sizes... we can’t do “small” with suspension forks!

Best,

Dan.

Hello,
For what it is worth, here is an opinion on Thorn cycles!
Thorn with Andy Blance the main 'designer' decided that Rohloff equipped bikes were/are the future for them. I know this because Andy told me so himself.
After extensive holidaying (oops research) in South America arrived a Rohloff hubbed cycle built like a tank! The bikes whilst slightly refined are in my opinion over engineered and still really pretty heavily built.
Now that most of the World's expedition cyclists have been and looked, purchased and gone, my own feeling is that Thorn should reduce Rohloff building and concentrate on a future for derailleur cycles for which most of the UK at least (plus the Emerald part of the Isle) use!
Rohloff for certain riding, OK but the rest of us ride and indeed love derailleur powered (?) cycles especially Thorn.
Also the build of the frames could be concentrated on with a more luxurious look/feel to them. More carbon forks as after all most people ride with carbon forks and seatposts?
Just my own opinion but I do know a great deal about bicycles and cycling, even though limited by health issues these days.
Best to all,
John

100% agree these rohloff are not for everyone i dont really care if you can cycle to mars and back without it breaking down  i want a  derailleur system . shimano and campag has served me well this past 40 plus years .
and why doesn't thorn offer more  colour range to there bikes jasus lads a bit more thought into the colour sceme wouldn't go a miss.
i think Andy Blance as good and all as he is is stuck in a ruth ,
time to up the anti Andy boy.

Hi John
i know where your coming from i have 3 thorn derailleur bikes +1 hub or derailleur all 26"
i'm not really interested in any of the present Thorn line up as i already have a Sherpa and i can't ever see me buying into the Rohloff hype so there is nothing else (size 13uk feet so 700c isn't for me)
BUT if Thorn restarted making lightweight/sporty tourers in 26" i doubt i'd of bought the used or NOS ones that i have,

all the super light camping gear you can get these days means a lot of people aren't going to need a tank for their kit, could be a big market again as cycling seems to be getting more popular all the time
as for you saying about carbon parts, i'll never buy into that one either
but a well built and finished stainless or titanium frame set with the proper Thorn headbadge not the stick on one, and i'd be saving hard and ebaying my hoarded goods  ;)

it would need both disk and v brakes, full rack and mudguard mounts, mech hanger, and pukka fork leg braze ons and frame internal routing for a dynamo's wiring for me

i suppose sliding dropouts and be able to use a belt drive to keep the "hoff" fans happy  ::)

it would be a real bonus if it was UK built, even better if it was English

lol i can dream

 see heres another thing i can't get my tiny brain around,
why no carbon, :( if mark cavandish cant brake carbon then u can rest assured we ain't going to do it any damage ,
as for disc brakes  the pro's hate them,reckon in a pile up there going to cause serious damage to riders, there happy enough with what they have..

i agree a good strong fast tourer is whats needed . ;)

jags you can have as much carbon as you want, me i simply don't trust it http://www.bustedcarbon.com/
never will either
Reynolds 921 sounds the business to me, no paint just satin or brushed tubes and polished stainless lugs,

edit
 unlike me cavendish aint a porker also he doesn't carry 15k of  kit on his bikes
and as for disk's they might be a bummer in a race pile up, but i don't race

Bill when lightweigh steel came on the scene first the talk was  it will break going over a bump, never happened .i have great faith in carbon there guys that tour on carbon bike's  be it  lightweigh but still they don't see it as been dangerous.

yeah i like your choice in frames but also like painted frames with plenty bling. ;)

Every company decides what their desired market is.  Maybe Thorn decided that they only want to focus on the more expensive side of the market?

 yes your right, expensive indeed,
but why make your frames in Taiwan if you want the expensive market?
it's just that they used to make some really nice lightweight derailleur bikes that are "fun" to ride, that in their time weren't exactly cheap, and some of us still think they are awesome
sorry to swim against the flow of the "Hoff"

yes i know i can go elsewhere but thorn are local and i have a certain amount of brand loyalty,
I just can't see why no sporty model when it only takes emailing a design to Taiwan and get them to bash out a 100 or so, if On One Can then Surly sorry surely Thorn can

Does the Audax Mk III not do the business? Graham Smith in Oz reckons it's the best bike he's ever had, & uses it for light touring as well as commuting, brevets, and such.

Just thinking about derailleurs in my life again starts to bring on a headache, so they're not for me, but they evidently works for lots of others.

Hello,
The Audax Mk 3 rides great, the issue I have with it is that it does not have what 'jags' calls 'bling'!
As for derailleurs , the World rides them to all intent and purpose without problems, even kids can fix them. Most people including a lot of cyclist I have talked to, have never heard of Rohloff, let alone seen one!
I have no argument for or against but Thorn really should bling up. Ive had loads more Thorn bikes than anyone on the Forum and each time I try to build a bit brighter (to look at) bicycle. I have a Mk 3 in progress which will be ridden New Year. It is blue with DC 07 carbon forks and returns me to the first Mk 3 I built in blue!
I feel that the real reason Thorn appear to frown upon carbon is to do with giving a Warranty? After all St John St Cycles sells carbon forks!
I have more time and space than most due to ill health and making my bikes look good takes time and effort. I have other bikes (not Thorn) and the appearance is more shall I say 'expensive'? Thorn frames are cheaper than some admittedly.......
Best to all inc Rohloff riders!
John
Best to all,
John

no YOU miss the point, no one is dissing Thorns, we have our Thorn full on tourers mines a sherpa, yours is a hoff based model
I don't need yet another full on tourer do you? but another Thorn if it was right? i'd have one  ;)
I'd like something like a modern take on an xTc, modern tubing (stainless) and fittings sporty and fun, bling would be nice,
it isn't likey to happen unless people declare an interest, even then i doubt Thorn will change tack,
Hoff or sod Hoff seems to be the way it's going

Great photo, Pete. A bit more iron oxide in the mud, and it could be Zimbabwe's Vumba Highlands :-)

John, on the bling thing:  This can be fixed easily enough. A friend was saying he wanted a better-fitting set of handlebars, so I suggested he look at the Grand Cru rando bars which Velo Orange sells. He's a casual cyclist, and hadn't really dipped into specialist suppliers, etc. He was quite taken with VO's offerings (the man has taste), and remarked, "Bling for bikes!"

So, a machine like the Audax could be tarted up with some quality shiny bits, though Graham's Fast Red Bike hardly needs them.

Thorn make plenty of derailleur bikes, plenty in 700C wheel-size, and even some that will run disc brakes. But carbon does not make a wise touring bike choice.

Yip that was my beauty right enough class act ,no idea how u dug up those photos .
i would no more use that bike for touring than i would my present one.
but i would use carbon on a touring bike as in carbon forks.safe as houses give better steering .those heavy forks on the nomad and sherpa  are the pits like trying to steer a tractor with no power steering. :o

anyway im going to take a look at my photo album seening you had the good will to post it up.

Google search for Look KX Light

Not so sure about the "better steering" claims. Steering qualities are mainly determined by the fork/frame geometry. Fork material plays stuff-all of a role in this. You could have a carbon fork that was lazy and stable, or a steel fork which is twitchy and devilish to control.

Steering requirements vary greatly (as I alluded to) dependent on the type of riding (speed, rider weight, load weight, road types) that is involved. What is a grand steering fork for one rider will be trash for another. Carbon forks are in no way automatically better steerers. Their major benefits are lighter weight, and slightly better shock resilience. Their downsides are the near-impossibility of safely mounting any front pannier racks, and a possible elevated risk of sudden failure after minor damage.

I have much greater faith in steel forks.

LOL they make 3 derailleur bikes a sherpa in 26, club tour and audax  in 700c, hardly "plenty" by anyone's imagination
take a look at their back catalogue, they used to make "plenty" of derailleur bikes and that was when their reputation for tourers was made
they also used to bang out great new bikes on a regular basis, so why not now? i could understand it if they still made all the bikes by hand but they don't and can out source to a reputable builder as they do now

btw if you look up the post i agree about carbon  ;)

Yes, so it seems they have rationalised their range to some extent - they make three derailleur bikes and three Rohloff bikes, in the single bike range.

I don't see that as limiting their range, bearing in mind that Thorn are a fairly top-end touring line of bikes. The carbon wunderbike, nor even the bling roadie, is not really in their market.

I think their last new bike was the Mercury, about three years ago. Before that there was the Rohloff tandem, the eXXp, the Nomad MkII, and I think the Raven Enduro. Yes, they have all been Rohloff. I am guessing that this is the direction they see quality touring bikes heading. My experience here in distant Melbourne has been that many more of my friends are touring with Rohloffs. 15 years ago there was just one person using a Rohloff in our touring club - today there are at least 12 enthusiastic Rohloff users all happily travelling on tours and commutes with them.

You have this the wrong way round, Bill.

It's easy to "to bang out great new bikes on a regular basis" -- weekly, if you're feeling frisky and are of an indecisive frame of mind -- IF you make your own frames on the premises. If you're paying the wages of your designer and brazier anyway, you can take the chance that at least one customer wants a bike like that. The opportunity cost is a few quids' worth of tubes.

However, if your outsource your frames, even locally, you'd better have your mind made, and limit the wastage of bikes that customers don't want, because now you have to sell at least a few handsful of bikes to pay someone else overheads to develop your frame.

And if you outsource to Taiwan, you'd better be certain several hundred customers of precisely the right size will want that new bike, 'cos the factory in Taiwan won't even look at your drawing until you're ready to make a minimum order of a container-load of frames, very likely only one size per container.

At each step, you can make fewer newly designed bikes because the money at risk becomes geometrically higher.

That's just the pressure of the economic reality of mass production.

Besides, it is sound management when you're small manufacturer to identify your niche and exploit it thoroughly, and then to grow into the next-door niche rather than attempt to do something radically different, because the radically different market belongs to someone else, and anyway comes at a higher general risk than the niche next door, whose customers will probably be aware of your reputation.

***

Thorn was a small provincial bike shop that transitioned brilliantly into the internet/multinational/online business age. But in the process it was inevitable that it would shed its past as a custom or semi-custom bike maker, and that in the end the product lines would have to be rationalized to protect the ability to offer the Thorn unique selling point (a genuinely capable and proven design, not just a cafe tourer) and of course to reduce wastage. I cringe when I see how often Thorne has a sale of their own frames and bikes, a direct result of the huge number of sizes they stock, combined with the minimum frame order necessary in Taiwan.

***

As for the nostalgia trip of derailleurs, there are plenty of custom bike builders who'll build you a traditional road bike or tourer or anything you want, as long as the tubes for it come off the shelf. Bob Jackson builds a very tasty bike and will put all the bling on it you want to pay for. www.bobjacksoncycles.co.uk But Bob Jackson's is a different kind of provenance from Thorn's provenance. Refer back for what I said about niches.

Someone else wants a stainless bike. Now, I happen to think Reynolds stainless is common, and a very good reason for riding a Thorn is that it isn't common, so if I'm going custom for a stainless bicycle I'd rather have a bike of Potte & Potthoff stainless steel, the Noblex brand. And I know just the guy to build it for you, and who has cornered the tubes too, but you'd better learn to speak German first, because he doesn't speak English. The thing is, Uwe has some proven designs to choose from, and the customer can alter the bike from there. A randonneur with fork (fitted, with a Chris King headset) starts at about £1100, but this will soon elevate if you want bling like polished lugs. Marschall Frameworks http://www.marschall-framework.de/produkte/

I'm not touting for business for these guys -- though they both have fine reputations and are definitely toutable -- but demonstrating how far Thorn has come from the niche it started out in, and how difficult it would be to do what you want it to do, which is to return to that niche.

***

I'm sorry to say that what you want, Bill, from a business viewpoint is irrational, an excitement for a few customers, of which very few will put their hands in their pockets, and which will therefore have to be financed out of profits. Compare that with the Thorn which had their brazier on the premises, at the beginning of this post, and financed a new bike design almost wholly out of ongoing, unavoidable overheads.

***

While the appearance might be that the economics has nothing to do with Rohloff hub gearboxes, actually the Rohloff is central to the niche that Thorn has carved out. If the Thorn advertising doesn't make the point explicitly, it should, that Thorn was one of the first to adopt the Rolloff and knows a great deal more about it than almost all its competitors. The Rohloff is one of the things that in several ways sets Thorn apart from the other bike makers. I can go into them, but this post is long already, and I'm sure you can list them as easily as I can.

Hi all

Andre i know exactley what your saying but a a few tweaks to their designs and they could have made a disk sherpa,they make a sport raven and standard raven, they could make a sport sherpa
if i was buying my Sherpa now i don't know that i would, as frames with disk brakes, bolt in swapout drop outs, full outer cable runs are easily available
i love my sherpa and am keeping it but i'm not so enamoured with it that i can't see what i'm missing had i of bought a Troll

as for stainless 921 if i read right is much the same as normal steel, same hardness same tig welding/lugs and tooling so it would simply be a matter of swapping tube material  between standard and a deluxe model wouldn't it?

thorn make a great deal about their frames and racks being made of steel as they can be repaired anywhere with basic tools and skill, this is a completley the opposite reasoning behind the Hoff hub, if that does go wrong your stuffed and are stuck till it gets back from the fatherland, not even provision for an emergency mech hanger to get you out of the Poo, it might be reliable but what do you do when the hub is ten years old, risk it on a bg tour or replace it? cassette new chainrings and chain on a proper bike innit?

as for them being frisky in the past on their models, i agree just wish i'd been into cycling in the Thorn haydays
i'd have an Audax 26, xtc short wheelbase, nemesis but i wasn't, so i'll keep restoring older models  8)

I was just coming back here to say something I forgot to mention about the older models long since discontinued: a time will come when their value on the second hand market will start increasing precisely because so few of each were sold, and you can't get them any more. But I see you've touched on it already.

....if Thorn really want to rationalise their range swap out drop outs would be the way to go, no more EBB one frame for either gear system makes sense to me

Nah, Andy Blance has already said, in the context of the Gates Drive belt transmission, that the split rear triangle is an abomination. If he won't agree to splitting one side, asking him to split both sides...

But there's a fixed rear triangle design that has a separate axle hanger which can and does often incorporate a hanger for the chain tensioner necessary for derailleur setups. I have it on one of my bikes and it is vastly superior to the eccentric bottom bracket, but probably quite a bit more expensive to engineer well as precision machining is involved.

that's the sort of drop out i had in mind,
it might cost a bit more but it would really increase the market for the frames 
also the extra cost on the frame would be outweighed by the security of knowing you have a fall back should the hub die,
i might be tempted onto the Hoff bandwagon but knowing i'm scuppered should it die is the deciding factor

Every time you adjust the chain tension, you have to reset your brakes, and maybe any mudguard being used.

I call that an inferior system to the EBB.

You call it whatever you like, Pete. But I have a bike with slotted, sliding axle hangers like those illustrated (in fact Bernd Rohloff designed them for my bike) and I've never, not once, had to reset the brakes or the mudguards after adjusting chain tension. And the clearances on my bike are close.

An EBB has a known inevitable failure mode built in. That makes it an inferior system.

Lots of chat about the possibility of Rohloff hub failing. Does anyone factually know of any individual who has been stuck because of a 'catastrophic' failure? My hub developed an issue on a tour, slipping in a number of gears, (ironically in Germany and I was able to take it to an official service centre.) They couldn't sort the issue but contacted head office who offered to fix it and to courier it back to me within 3 days. Unfortunately I was short on time to catch a plane so took their advice which was "Ride it anyway, your hub will not completely fail.""No one has ever been stuck through a catastrophic failure."I rode the 800 miles to Budapest and sent the hub off for repair when I got home to Scotland. No warranty - no questions - no charge - great service.

Interestingly enough, when discussing the pros and cons the the Rohloff, loads of talk goes into "what if it fails?" or, "it's expensive but cost less over the life of the hub compared to replacing a derailleur system." No one seems to talk about how good it is to ride with. I'm not knocking derailleurs (having just ordered a shiny new Thorn one - one week and counting). Sure it's not infallible,but I don't agree that the Rohloff is simply 'hype.'

Jags, stop being facetious. No-one is saying that at all, certainly not I. All I have been contending is that for much touring, especially extended, fully-loaded touring, or into remoter areas, the questions of durability are a real issue. One I'd rather not have to deal with out on a tour. And one of much greater reality than a Rohloff hub 'failure'.

Now if you can show me a well designed carbon touring bike that can  take front and rear pannier racks, is warranteed to carry 25-30kgs of gear plus the rider, and there has been sustained use of such a bike by long-distance tourers, I shall change my opinions on this.

But carbon has been shown over time to be well-suited to day rides, racing, café-touring, and maybe even some of this bikepacking lurk.

Now now il padrone be nice  to anto.  ;D

carbon is the way forward  when it comes to cycling frames and groupsets  and probably jet planes   racing cars .. i said before im not interested in adventure touring  tarmac does it for me as smooth as butter tarmac .
how did adventure   cycle tourist ever cross  the planet before rohloff,  truly  amazing they even got 100 yds up the feckin road with all that loaded gear.

billc c if you want a gem of a bike   doesent matter the frame although the sherpa would do the job then  fit  campag reckord carbon groupset  or shimano dura ace d12 and away u go for as many miles as your little legs will take you trouble free  cycling.

dunno what Andre meant
 but i assume that it's you only get to adjust your chain a few times before you have divots in the bb and further fine adjustments are out the window unless it's replaced, the sliding dropouts Andre posted pics of allow adjustment without damaging itself in the process, surely thats a superior design? and as a bonus you can use a rear mech so not only better for the Hoff's but better for us luddites  8)
also you said about adjusting brakes and mudguards with sliding drop outs, fair enough
but with an EBB you are shifting your bb so your pedals and riding position must be affected no? i know my bad knee noticed it on my old ebb scott when i tightend the chain

I put a very short post with a photo up a little while ago; I had written a longer reply / comment to this thread, but then got timed out, so rather frustrating!!

But putting my head (a little) above the parapet . . . .

Rohloff / derailleur debate – I reckon this has been well aired over the time I have been on the Forum.  If I was commuting regularly, or riding in mucky conditions like the photo above or as shown in the earlier picture here (where is that??), I would go for a Rohloff.  The guy who bought my RT rode it to the Far East, with as far as I know few bike problems other than a spate of punctures at one stage.  I now ride a Sherpa, derailleur of course, and that suits the lower mileages and generally better conditions of my present style of riding – despite the real concerns over wear rates etc., derailleur systems function much better than they used to.  But if my needs changed, I would go back to Rohloff – if I could afford it. 

And as far as the Thorn range is concerned, I still reckon the range is pretty much the best.  Whenever I buy kit, or browse in local or chain bike shops, I am often asked what I ride  . . . .

“ A Thorn?? Gosh, really heavy then.”

I insist they have a look at the bike, and they are invariably surprised – they point me towards the Dawes / Ridgeback or similar range, and I point out that those bikes are in fact mostly heavier than my Sherpa as I have it kitted out, sometimes much heavier.  I am planning a long tour next spring, the longest I have ever done in my 69 years, and I reckon the Sherpa will look after me.

And as for bling, my idea of bling is a decent, well-sorted and well maintained bike.  I have a Lion brass bell mounted between the steerer tube spacers, and that’s about it.

Sure it's not infallible,but I don't agree that the Rohloff is simply 'hype.'

I've never heard of a Rohloff suffering a catastrophic failure; in fact, I've never heard of a Rohloff which failed to get someone to his destination or at least home again before going in for service. Rohloff's amazing service stories like yours are recounted because there is nothing else to talk about, and even those stories are few and far between when you grasp how many Rohloff boxes there are now (well north of a 100,000). If there is ever a catastrophic failure, you can be absolutely sure the naysayers will wake us up within five minutes to say, "I told you so!" Almost always the people who want to talk about a Rohloff failing are the ones who don't have one. The guys who have one, or are actually planning to buy one and have done their homework towards the purchase, never feel the need to talk about the box failing.

As for your perception that "No one seems to talk about how good it is to ride with", I honestly don't think that is true.  I talk about how good the Rohloff is to ride with all the time, and so do many others here. It's just that people notice bad news (or in the absence of bad news the gossip of schadenfreude, like much of the ignorant nonsense we can see even here sometimes when people get stir crazy in the winter) much more than good news.

Also, every now and again a knowledgeable derailleurist of long standing considers converting to a Rohloff and then asks a whole row of sensible questions, and he gets to hear a lot about how a Rohloff box enhances one's pleasure on the bike. The last time we gave the non-mechanical factors of the Rohloff experience a thorough outing was when Dan Wood converted, with a couple of smaller outings since, though of course those recently-converted fellows could read the standing posts. Seven years ago I read every word on the Rohloff on this and several other boards in several languages before I splashed out the price of a good preloved BMW on a bike with Rohloff box; there was already quite a bit of user-generated literature, both mechanical and psycho-ergonomic, and there's a lot more now, here and elsewhere.

A day will arrive when the dimples made in the soft ali of the EBB by the fixing screws will run together and the thing will turn in the BB shell without your assistance. If it happens in Outer Dirtyanddesolate, and you can't get the chain tight enough to pedal, you'll be pushing a long way through the desert. That counts as a catastrophic failure in anyone's book.

but with an EBB you are shifting your bb so your pedals and riding position must be affected no? i know my bad knee noticed it on my old ebb scott when i tightend the chain

When I fitted the n'lock, which is in fact a new stem, I couldn't get an adjustable one in black, and so fitted a fixed version after taking very careful measurements. I got the handlebars to within 2mm of where I had them before. You've think I wouldn't notice, eh? But I did. Later, after I fitted a new seatpost and a rail adapter for my twinrail Brooks saddle that Julian sent me, I was within 1mm, and still I noticed it.  I also noticed that I was coming a bit forward over the pedals and that the power of my stroke suffered.

Okay, so maybe I'm just ultra-finicky about my comfort, or maybe my senses were heightened because for most of this time I was in and out of the hands of the cardiologists and couldn't bend over the bike for long. Or maybe it really matters. I certainly think a 5mm shift in pedal position would be noticed by most people.

Certainly the EBB can fail that way, but with a bit of care that failure can be avoided. Just make sure the dimples are well spaced. It's not trivial but it's not rocket science either.

Hmm, here is a method I haven't tried yet but I bet it would work.... the nicest method is just to look down the screw hole to see the dimples. But it might be too dark, dirty, etc. One can feel the dimples just using the grub screws themselves. But that is awkward. So another scheme: use something like a nail or a toothpick to run down the grub screw hole to feel where the dimples are. It's not that hard to maintain good dimple spacing!

Post by: rualexander on December 06, 2015, 06:04:21 pm
Another problem with the EBB is that by the time it comes to needing adjusting, the thing has seized in the bb shell, and needs prolonged work with penetrating oil and a large mallet to persuade it to move, even if it has been greased before fitting. I've had to do this a couple of times on my buddy's Raven, once while on a four month tour in New Zealand.
I like the idea of the sliding dropouts more than the EBB, but they maybe have their own issues over time.

They do; no system is perfect.

A friend with the Rohloff sliding dropouts has an issue adjusting them when his Topeak SuperTourist rear rack was mounted -- the lower mounting tangs extended beyond the bolt holes and limited travel.

Similarly, another friend had trouble after commuting for several years in salty conditions He said there was not rust, but a lot of "stickage". I think more frequent/careful maintenance and perhaps the application of some anti-seize between the dropouts and wheel mounts and bolt threads might well have helped.

A third case of difficulties with sliding dropouts came not from the dropouts, but from thoughtless frame design. The rear stays were very short and the chainstay bridge was placed in such a way as to make wheel removal impossible when the dropouts were slid fully forward A puncture repair required loosening and sliding the dropouts.

Like anything, really; proper design followed by good user maintenance help, but no system is perfect. Wedge eccentrics can be a bear to loosen once the wedge has "seasoned" in place. Split-shell designs can become difficult over time as the clamp-bolt threads wear. The better split-shell designs use replaceable nuts keyed to the shell-flange interface. As for eccentrics retained by grub screws, all is not lost if the dimples run together. Thorn left enough takeup in the threads to hold even a corrupted insert securely for a bit before replacement is required. My tandem uses cup-ended grub screws that leave little rings in the aluminum eccentric, rather than dimples. They prevent gouging, but fine adjustment can be a bit difficult/coarse if the embossed rings overlap. Doesn't slip one tight.

In the end, it is six-of-one/half-dozen of the other. If a bike has neither eccentric nor sliding/ramped dropouts , then the alternative is a chain tensioner. If one has to go that route, one with a single tension pulley is probably best as it avoids putting the chain through a tight wear-inducing S-curve.

Best,

Dan.

Rolhoff was on the market looong before 9-speed, and before most disc brakes. It has an almost 20-year market presence.

and still 99.999999% of cyclists don't have a clue what they are, so much for market penetration eh? pretty sure iif they were the game changer you lot reckon, they might just be a little more widely known, still you'll never need spares or repairs so no matter

Now you're just changing the topic to suit your biases.

I was referring to the idea expressed that Rohloff is some new technology that is just a lot of marketing hype (something I will agree a lot of mass-market pap IS). For sure, the Rohloff has not gained mass-market penetration - there are currently only something over 211,000 hubs on the roads. Went from hub #134827, to over 211,000 in just under five years. It never will be a mass-market product. That does not however deny its functional values.

Yeah I would be happy to have a wider range of gears than the Rohloff provides!

But there are more advantages than reliability. Very fast shifting at very low speeds is grand fun, e.g. to switch from standing to sitting and back when crawling up a steep hill. Also a nice wide range without having to coordinate front and rear shifts.

Plus of course being able to use a full chain cover.

Good luck to you if the derailleur suits you. I really do not see the grounds for bagging the Rohloff to the extent you are, a gear system that works VERY well for many happy users. It does verge almost on the insulting at times with the tone you have chosen  >:(

So far, so good, but I'm watching both sides and will step in if things become personal rather than directed at the relative merits of each gearing system.

Personally, I own bikes of both sorts and love them equally. I own "only" one Rohloff -- the Nomad. It's sealed construction has been well-suited for my expeditionary use in heavy mud and alkali dust, and it is nice to have no worries about chain-suck or a down-hanging derailleur cage while riding cross-country through sagebrush and other things that could foul a derailleur. That said, neither kind of drivetrain has held me back, nor proven superior or inferior in *all* circumstances.

A major reason I prefer *older* (5-, 6-, 7-, and 8-speed half-step) derailleur systems *and* the Rohloff is for extended service life and reduced maintenance and replacement intervals. I can burn through several complete 9-sp derailleur drivetrains (chain, 2-3 chainrings, and the most-used cogs on a riveted cassette) in the course of a summer. Over time, this is more costly to me than a Rohloff drivetrain would be (longer-lived thanks to a straight chainline, stainless chainring and cog, and no chain deflection or tensioner). Similarly (but not to the same extent), my older derailleur gears are also long-lived (thanks to thicker cogs and chainrings and half-step-and-granny gearing that results in my most-used combinations having almost no chain deflection and near-equal use of the middle and high chainrings to spread the wear). By happy circumstance, my Nomad's 26x2.0 tires coupled with 36x17t gearing results in almost identical gearing to my favorite 15-sp half-step on one of my randonneur bikes. The Rohloff's high isn't as high as the one I don't use on the derailleur bike (but need for the lower gearing combinations to work) and I have two lower combinations which I use regularly while touring with a load.

Both systems work well for those who own them. Derailleur gears have been around a long time, and so have IGH (interally-geared hubs...think Sturmey-Archer), and each have proven remarkably long-lived given most riders' general lack of maintenance and drivetrains that are usually exposed at least in part to the weather. Having ground both drivetrains through really severe conditions, I firmly believe the Rohloff has the edge in one regard: It will work with less maintenance and fusswhen used continuously in truly mucky conditions where it is impractical to perform regular service or cleanup. In similar conditions, my derailleur bikes also do fine, but for a shorter period and they require religious maintenance. At home the difference is slight. On an extended tour across dry lake beds (and especially if there is rain) the Rohloff wins this one category hands-down for me in my use.

For me, it is "horses for courses", vive la différence, and you pays your money and takes your lumps.

Best to all,

Dan. (...who is watching this spirited debate with great interest)

I'll open it up again in a bit. Meanwhile, it would do us all good to back away from our keyboards and go for for a ride on whatever we happen to have. Last I checked, all involve pedals somehow turning a rear wheel. What comes between matters naught so long as the birds sing, the breezes are soft, and we get out in the world on this wonderful machine called a bicycle.

My first post repeated!Hello,
For what it is worth, here is an opinion on Thorn cycles!
Thorn with Andy Blance the main 'designer' decided that Rohloff equipped bikes were/are the future for them. I know this because Andy told me so himself.
After extensive holidaying (oops research) in South America arrived a Rohloff hubbed cycle built like a tank! The bikes whilst slightly refined are in my opinion over engineered and still really pretty heavily built.
Now that most of the World's expedition cyclists have been and looked, purchased and gone, my own feeling is that Thorn should reduce Rohloff building and concentrate on a future for derailleur cycles for which most of the UK at least (plus the Emerald part of the Isle) use!
Rohloff for certain riding, OK but the rest of us ride and indeed love derailleur powered (?) cycles especially Thorn.
Also the build of the frames could be concentrated on with a more luxurious look/feel to them. More carbon forks as after all most people ride with carbon forks and seatposts?
Just my own opinion but I do know a great deal about bicycles and cycling, even though limited by health issues these days.
Best to all,
John

As for your perception that "No one seems to talk about how good it is to ride with", I honestly don't think that is true.  I talk about how good the Rohloff is to ride with all the time, and so do many others here. It's just that people notice bad news (or in the absence of bad news the gossip of schadenfreude, like much of the ignorant nonsense we can see even here sometimes when people get stir crazy in the winter) much more than good news.

The point I was making, with the exception of this forum ( I agree with you there), my 'real life' conversations when someone (who has invariably never seen one 'in the flesh' before) spots my hub always seem to focus on the "Expense", and "What will you do when it goes wrong?" The only country I have toured through that has been the exception to this is Germany where no-one bats an eye lid at what you ride. Funny enough when I took my bike (Koga Signature) to the Rohloff service centre, the owner had no interest in my bike (except to look at the hub issue) but positively grew tumescent when he saw my wife's Sherpa! "This is the first time I have ever touched a Thorn!""Look at the design of the forks!" Etc, etc...

FWIW, my five cents' worth (use'ta be two cents, but with the shrinking value of our petrodollar 'n' all…) on Thorn, Rohloffs, and derailleurs:

1)   What I like most about riding my Raven-mit-Rohloff, is that I rarely think about the hub -- I just change gears, sometimes 2 or 3 at a time, and it always gives me the gear I want, no fuss, no confidence-sapping doubt, nuthin'. It just works.

      Occasionally I do think about it, usually when coasting downhill in 13th or 14th, making a terrific ratchet-clackety noise like a large swarm of African bees (or like a high-end Cervélo road bike) without the fear and loathing that a large swarm of African bees would provoke.

      And just the other day I thought about it, too:  Rolling along beside the river in 11th gear, alone on a bike path in early December :-), I was trying to figure out what made more noise--the hub, my 'glider, or my Marathon Supremes. I decided that the hum of the tires covered everything else.

2)   As for Thorn bikes in general, my experience is limited.  I've ridden a few thousand ams on my Raven, and would have no hesitation in recommending it as a touring bike.  The Nomad is obviously a well well made expedition bike, but more than I could use.

      Thorn has made a bet on Rohloffs, but they're not alone in doing so -- see Peter White's site, for example: http://www.peterwhitecycles.com/index.html (http://www.peterwhitecycles.com/index.html)  It's possible that that market niche will expand in the medium term, if & as cycle-touring grows, with a nudge from retiring boomers.  Thorn's bikes are hardly bargains, but they are good value, compared with the trekking bikes sold in Germany on the one hand, and with the products of custom or specialty firms in North America.

       The Rohloff is not the whole story, however.  Thorn makes some quality frame components as well. My Eclipse touring bike has carbon forks, which now have 12-plus seasons on them, and although I plan to use the Eclipse for day rides, I am not at all keen to test the forks' durability any further.  I'm thinking to make the Eclipse a rehab project, starting with a pair of Thorn 853 forks for the Mercury. (Fork #5 in the Mega-brochure.) The dimensions fit my Eclipse nicely, and the lightweight steel forks have threaded tabs for fenders, as well. (Currently, I'm using clamp-on Planet Bike plastic fenders, which sorta-work, but not really, as PB's "hybrid" variants are too short for what I want, so I've modded a rear fender, etc., etc., and why am I doing this, just on account of carbon forks anyway?)

      The idea of rehabbing the Eclipse with a nice steel fork is appealing, partly because it lets me take advantage of Thorn's long steerer tube to raise my bars a couple of cms. The Mercury fork will accept my Avid canti's, though I might get a spiffy new set, Mavic A119 or Alex Adventurer rims will work for my purposes, and I can keep my 35 mm Marathon Racers, which I enjoy. With the addition of a proper front fender, I think all that will make the front end of the Eclipse a whole lot more functional and comfortable, and I won't have the nagging "What if…?" question at the back of my mind as I approach next spring's crop of frost heaves, cracks, and potholes.

      Less appealing is the prospect of finding a derailleur/chainring/cogset/shifter package that works when I need it, though I've resigned myself to the expense of swapping out my current setup, the fourth such change in ten seasons.  I think I've learned enough to know what I want, though whether that's still on the market remains to be seen.

No hands-on experience with pedal-bike shafties, Dave, but I first saw them on a visit to Québec City in 2008.  The rear half of the bike looked a bit undernourished or denuded, but the combination of bevel drives fore and aft looked elegant, if nothing else. The ones I saw had an IGH, but I don't know what it was. I sorta liked the idea of twin shaftie two-wheelers in yard, Hans the airhead and a pedal-bike cousin, but it never happened, 'cos --

I asked my then-LBS about them, and they said they'd carried the for a season or two, but had encountered reliability problems, and not enough people bought them. I didn't pursue the specifics (IGH?) (novelty only?)

One of the Five Horsemen of the Cycling Apocalypse  ::) :P :(


Along with:

Oval/ellyptical chainrings
Automatic gears
No-nose saddles
Airless tyres


All first developed for bikes in the 1890s bike boom. All periodically re-invented (about every 5-10 years). None ever truly commercially successful, to the point of mass-market adoption. Much less successful and accepted than the Rohloff  ;D


Quote from: Sheldon Brown
Shaft drive

 An alternative drive system, replacing the chain and sprockets with right-angle bevel gears and a shaft running inside the right hand "chainstay."
Shaft drive was briefly popular around 1900, and occasional attempts are made to revive the design. Unfortunately, shaft drive turns out to have more problems than advantages.

A shaft drive requires heavier frame construction around the bevel gears to maintain their precise alignment under load. The drive system is heavier and less efficient than a good chain drive.

For reasons of clearance, the bevel gears of a shaft drive bicycle must be considerably smaller than the typical sprockets used with a chain drive. The smaller size of the gears causes an increase in the stresses on the whole support system for the shaft. This problem is exacerbated because the stresses from the shaft drive are not perpendicular the triangulated structure of a bicycle frame, and so are not well-resisted. .

Most of the advantages touted by proponents of shaft drive are only advantages compared with open-chain, derailer gear systems. Many proponents of shaft drive use specious (if not dishonest) arguments "comparing" shaft drive systems with derailer gear systems. Any such comparisons are meaningless, it's like comparing apples and locomotives.

A valid comparison of shaft vs. chain drives can only be made if both bikes use the same type of gearing, whether single-speed or with an internal gear system.

These same advantages can be obtained with chain drive using a fully-enclosing chain case, as with old English roadsters and many current Dutch bikes.

Shaft drive proponents also often compare sealed, enclosed shaft drive systems with open, exposed chain drive systems. This is also a misleading comparison. All of the advantages claimed for shaft drive can be realized by the use of a chain case.

Once the shaft-drive's bevel gears wear a bit their efficiency plummets. Whereas a conventional chain drive maintains close to 97% efficiency and loses really very little even when worn.

Devil begone !!

 Much less successful and accepted than the Rohloff  ;D

shaft drive = Much less successful and accepted than the Rohloff 

so follow that reasoning and ?
rear mech and chain?  Much more successful and accepted than the Rohloff  8)

why fight it derailleurs are still very much better than hubs for a lot of us, and most of the arguments against hub gears are in sheldons description of shaft drive

chain and mechs =
not as complex
not as heavy
not as expensive,
more effcient
greater gear range
easier to remove rear wheel

before you say i'm starting to slag the hoff again remember i didn't know what a hoff was till i signed up here 6 years ago everything i have read about them has been on here,
you lot do Rohloff no favours with all the constant moaning and angst you write on here about them,
to us mech uses it just seems like it really aint worth it after reading all your posts
sorry but i'm impressionable and the impression set here is a lot of expense and constant faffing, not of an ultra reliable worry free bit of kit

but look mechs work to perfection and they don't cost the earth unlike rohloff.
so why build a bike around a rohloff hub.

Title: Re: Whither the future: Thorn's derailleur vs Rohloff bikes
Post by: David Simpson on December 08, 2015, 05:39:19 pm
These are valid points, and here are my thoughts.

Disclaimer: I have a Thorn Nomad with a Rohloff, and I think the Rohloff is great (for my purposes).

why fight it derailleurs are still very much better than hubs for a lot of us
That is the key point: "for a lot of us". Derailleurs will be around for a long time, since they work great and have been refined for decades. Those of us who love Rohloffs are not saying that Rohloffs are the best for everyone and every situation. But for certain situation, Rohloffs are superior to derailleurs.

not as complex
True, but complexity must be weighed against the benefits that a more complex device provides. If simplicity was the overall goal of a bike, and we removed any component that contained any hint of complexity, we would end up with walking stick.

not as heavy
True. However, the weight gain of the Rohloff is not as much as some people think, since you need to subtract the weight of the additional chainrings, the front and rear derailleurs, and the sprockets. Also, the weight is concentrated at the center of the wheel, so it has less effect on rotational momentum (acceleration). But yes, the Rohloff does add weight.

not as expensive,
Your honour, my client pleads no contest, except perhaps insanity. Guilty as charged.
[Edit: While the up-front cost is much higher, I believe that in the long run, the Rohloff will actually be cheaper than a derailleur because of its extremely long service life.]

more effcient
Yes, but only slightly. I don't think you would notice the difference. The Rohloff website has a good article about efficiency:
http://www.rohloff.de/en/technology/efficiency/index.html (http://www.rohloff.de/en/technology/efficiency/index.html)
Ironically, the Rohloff is a German design, and I have never heard of the Germans been accused of inefficiency. :)

greater gear range
Yes, this is true. When I switched from my 27-speed mountain bike to my Nomad, I gave up the top gear. My bottom gears are almost identical, and the top Rohloff gear is almost the same as the second-top gear on my derailluer. Since I ride a lot of hills, I gave up the top gear rather than the bottom gear. I would argue that while you do give up a bit of gear range, a 526% range is still sufficient for most cases.

easier to remove rear wheel
I don't understand this point. In both cases, you undo the axle nut or quick-release and drop the wheel out. Are you referring to needing to reduce the chain tension before removing the wheel on a Rohloff? I've never needed to remove my wheel (so far -- it's only been 2-1/2 years), so I can't remember any additional steps.


sorry but i'm impressionable and the impression set here is a lot of expense and constant faffing, not of an ultra reliable worry free bit of kit
Yes, a lot of expense, but I haven't heard of "constant faffing". (What does "faffing" mean, anyway? Tinkering and adjusting?) Maybe you are referring to different ways of tensioning the chain. I love the Rohloff for the precise reason that I don't need to do adjust, clean, or fix it. I do a lot of riding in the rain, and my derailluer didn't last long with all the road grit in the gears. Also, I ride in city traffic, and have a Rohloff is almost like have a (semi-)automatic transmission. I'm always in the right gear, and changing gears is effortless and always precise.

ps i hope this post isn't going to provoke more arguments
Me too. Debates about the technical merits of a design are good and helpful, but name-calling and personal insults have no place here.

I love my Rohloff, but I realize that it is not for everyone. In the same way, I love my Nomad, but I realize that many people would call me an idiot for commuting up my hills with a heavy bike. I don't care. It works great for me.

Are you guys -- Bill and Anto -- for real? You don't compare a Rohloff to an Alivio and then say one is expensive and the other is cheap. The sort of fellow who splashed out on a Rohloff has at least considered a Dura-Ace transmission, or probably had one on his bike, and compared to the number of Dura-Ace transmissions a high mileage cyclist will wear out before a Rohloff breaks down irretrievably (hasn't happened in about twenty years and over 200,000 units, I remind you), a Rohloff is the cheap option.

Not that it matters that the Rohloff is the cheap option, because that's about number 99 on the graded list of considerations; I just mention it because you did. A Rohloff has much more important advantages than that in the long term it will be cheaper than derailleurs. Here's a deceptively simple but very important triplet:

With a Rohloff you have the opportunity to fit a Chainglider and so you don't have the cost of chewed-up trousers bottoms and drycleaning and mending, and you're not getting your hands filthy all the time cleaning the wretched derailleur, and instead of cleaning the transmission daily, you're out there riding.

Andre --

That's a good point about the cost of the Rohloff. I was thinking about just the up-front cost. But in the long run, the Rohloff is actually cheaper.

If you honestly want a cheap drive system for your bike, then you should see if someone makes plastic chains and gears. Those would be cheap. However, they would need to be replaced fairly regularly (hourly?).  :)  I'm being silly, but the point is that up-front cost cannot be considered alone.

think greg lomond one of the greats  he rode carbon bikes.

im a roadie at heart .i will never do any adventure touring  so hub gears just don't interest me .so would i but a Thorn bike with Rohloff i doubt it very much,
but i would but a  audax or clubtour  both can take  panniers and bar bag  that will do this kid. ;)

(No, jags, don't leave.)

For me, I'm the opposite. I have never had an interest in skinny-tired lightweight bikes. I had a 3-speed (Sturmey-Archer) Raleigh as a kid/teenager, then got into mountain bikes in my teens. Lightweight road bikes always seemed too fragile for my liking. Fast, yes, but I've never cared about speed. I want to carry my gear and ride on any road or trail in any weather.

As for Thorn's business direction, it seems that they want to be the best touring bike manufacturer in the world, not the best over-all bike manufacturer in the  UK. They are focusing on a narrower market, but reaching the world through their online store. I'm on the west coast of Canada, and if it wasn't for their online store, I wouldn't have a Thorn. I'm in no position to visit SJS Bikes and browse their products in person.

Yeah it doesn't make so much sense to compare "Rohloff vs derailleur". Apples to apples might be "IGH versus derailleur" or "Rohloff vs. Dura-Ace".

It seems that the derailleur market is splitting a bit between cheap and expensive. The cheap stuff is OK for light use and the expensive stuff is great for sports fans, but for hard practical use... I don't follow the market, so I don't know. It was my 7-speed brifter dying that got me looking for something that would last... not just the device itself, but a supply chain that understands that I like to ride my bike & I don't want to replace the transmission every five years to keep up with standards that are constantly changing.

If simplicity was the overall goal of a bike, and we removed any component that contained any hint of complexity, we would end up with walking stick.
Not quite a walking stick, but I have the luxury of an old road bike (1972 Windsor Professional/Cinelli lookalike I bought for the princely sum of USD$20 complete) and have Big Fun Plans™ for it when I can find the time.

Currently setup as a 2x5 10-sp with Campagnolo Nuovo Record equipment, it will soon become a Draisienne (walking bike/balance bike alternative to a skateboard or scooter 'cos I've always wanted to try one), then a Fixed Gear ('cos I miss riding one), to be followed by a 2-freewheeling cogset/1-2 chainring retro-direct drive* and then probably will be restored in something close to its present guise for longer-term use.

I've never had a similar "go-fast" bike before (it has no rack or mudguard eyelets and I'm not inclined to braze them on this one) and the low price allows for Play, which is both important and fun.

There's a number of drive schemes that have fallen by the wayside. Among them...

*Retro-Direct drive for a mind-blowing experience: Multiple gears with no changer. Two (non)Fixed Gears, one high and the other low. Pedal forward for drive in one gear, pedal backwards for an additional ratio in the other. Forward drive can be low or high depending on how you route the very long chain. Add two chainrings and a front mech, and you can get a total of 4 ratios. Madness! For a couple video examples, see:

yup i'm for real i bought a xTc classic and a xTc fillet brazed frame in the Thorn sell out, why because i knew they were never going to make as good a bikes again for my needs
here is what sold me and here is why i think they should continue with mech bikes

Many of our customers say ... “I want an exciting lightweight cycle that I can go for a blast on in the summer evenings, that I can ride, lightly laden, over long distances briskly, and that I can also use for my annual touring holiday.” ... Well, this bike is for them! It will do all this and much, much more! If you want a good-mannered bike on which to cycle prodigious distances where ultimate comfort is more important than ultimate speed, then this is the perfect bike for the job. Don’t misunderstand, this is a very quick bike - one that encourages you to get out of the saddle and sprint up short climbs - but it is also very comfortable, especially over distance or over rough roads

Actually, there has been a huge improvement. My hub has the full enclosing case, not just the half shown in the diagram. That means that the gears and ball bearings are protected from the elements, and not visible as in the diagram.

Post by: leftpoole on December 09, 2015, 09:54:39 am
Hello!
As much as it pleases me to accidentally start this massive 9 pages (so far) debate!
I am not getting why it has moved on in such a massive shift in direction?
I simply (?) mentioned at the start that I personally (more or less if read between the lines)
thought that Andy Blance at Thorn had concentrated all efforts into holidaying (there I go again, testing and designing) on the South American Ripio whatever that is in English (rough roads) and only Rohloff for the future. He has talked with me and told me Thorn feel that their collective future is Rohloff based cycles.
My question really at the start was or should have been, why!?! Because in my belief there are many people who would buy a Thorn if it were an upmarket derailleur equipped bicycle. The current bicycles are really great and I have two so I am happy with them indeed having purchased used, modified and built my way have a great knowledge of them. Sadly health is getting me down and riding as I used to is never going to return. But I love cycling and love bikes and will continue to my dying breath ......
In my opinion Thorn should steer in a slightly different direction and get to grips with more road bikes (Audax & Touring) but not discs because my feeling is this will be a short sharp fashion ?
Other manufacturers are catching up fast and Rohloff can be specified by almost every manufacturer (of heavy duty or even cross bikes) somewhere.
When Thorn started out the bikes were fabulous, with fillet brazing and high prices. The Audax 853/ the XTC etc etc. We all wanted one or even two!!!
Thorn please brighten the range, please make some real UK built handmade frames for us  ;D ;D ;D
Best to all who return to the original theme.
John

hi John
the topic is never going to stay in a straight line, it is broadly going in the direction it started in
i have no more input i have said my bit
the only thing i didn't touch on is you want more bling, the only bling a Thorn needs is the stainless headbadge that they ditched, bad move, who wouldn't pay an extra few quid to have that back, POS stick on badge  ::)

btw not sure why you posted your last comment as this has been one of the better threads in ages, and your not happy with it LOL

perhaps it should of been split again and your original post would have died

btw i agree about handmade and British i have put it in my posts in this thread, some might say Thorn have sold out and are just another boutique brand now with just a vestige of their former glory days

Yes but they have to make money, and Thorn have chosen to occupy the niche that is the Taiwanese batch factory handbuilt touring bike (either heavy duty Sherpa/Raven/Nomad, or lighter duty ClubTour/Audax, plus a few Tandems).

If you want handbuilt in the UK, there are others who can supply that niche, but the volumes are much lower and the costs much higher (probably at least double on the price of a frameset).

They used to do more colours (most frames were available in four colours at least), but unfortunately only two colours in each model seems to be the option now, presumably for economic reasons, cost of ordering more batches, stock costs, etc.

Personally I think they have the balance between Rohloff and derailleur bikes about right just now.

As for bling, presumably most Thorn customers don't really want bling on their touring bikes.

Presumably Thorn know their market, sales figures, and customers better than the handful of us who frequent this forum.

This is manufacturing in general. Buy a bunch of parts, slap them together, ship them off, cash the checks. Easy money? Don't be ridiculous!

There are big trends in general global manufacturing, there are smaller trends in bicycle manufacturing, then there's the direction that Thorn is choosing inside those big currents.

Handmade bikes seem to get rarer and rarer. The increasing price of skilled workers is probably a big piece of this, plus automation keeps building better stuff at lower prices. This is a general global manufacturing trend.

Derailleur vs. Rohloff, yeah, that is certainly a place where Thorn is picking its own path - not exactly unique, but far from commonplace. Though IGH do seem to be getting more popular. I would say Thorn is an industry leader. You might not like the direction in which they're leading. But leading is very far from "easy money"!

Got to say, though... if I can just take 25 lb off my mid-section... the next weight will come off the bike... those Audax bikes sure look nice! I love my Rohloff but I would be very happy to expand the family!

Why do you call it "no name tubing"? Do you believe that their tubing is inferior to that used on other bikes? In their "Mega Brochure" [page 8], Thorn go into detail about the tubing used in their frames. The quality of their tubing is something that they emphasis.

Just curious what you are saying, because it sounds like you don't like the quality of the tubing.

i called it no name tubing as all the older ,dare i say proper Thorns very proudly told you of the reynolds tubes used in the frame,

i have to be really careful as i really am not trying to denigrate the new Thorns,
But John has talked about better/nicer/more upmarket frames like they used to be.
 i'm just adding a voice that says i agree the older kit is much more desirable
a lot would probably shell out the extra to get a Thorn like you used to
if they can out source mass produced frames, then at a cost to the buyer is there no UK frame builder they could trust with their design to make them?
yes it's going to be expensive it always was but more people spend big money on their dream bike than ever before
they even spend it on disposable carbon bikes  ;)

Post by: David Simpson on December 09, 2015, 07:05:39 pm
I didn't hear of Thorn until about 3 years ago, so I can't comment about their older models. But obviously they were (and are) well loved.

As for John's original comment in this thread... The direction of a business is primarily influenced by profit. "Where can the business make money?" Several people have noted this point in this thread. However, there is another influence that can be important, particularly in a smaller business: "What are business owners interested in?" Small business owners get into the business in the first place because of their interest in the subject, hoping to make money at something they are interested (and knowledgeable) in. As their interests change, the business may also change, provided that they feel they can still make a profit.

Mostly likely Thorn could make money selling bikes with frames hand-built in the UK. (These bikes would undoubtedly be more expensive than their current models.) But it feels like they just have no interest in that market. We can discuss the economic feasibility of such a venture, but if that is not the direction that they want to go, it just isn't going to happen. And that is what makes it frustrating for people who want those models: Thorn could do it if they wanted to, but they just don't want to. There is nothing preventing them from doing it, except for their own decision.

(Of course, I'm assuming that they could make a profit selling those bikes. I don't know for sure.)

i wasn't suggesting they stop what they are doing and start again from the UK, that would make no sense
 but an arragment with a builder to build one off custom frames to the thorn design, paid for upfront by the customer
it would keep loyal and spendy customers happy, not cost Thorn in wages, Thorn would make some coin for arranging it and allowing the use of the design and maybe keep a tradition alive, Handbuilt in the UK

yeah i know cloud cuckoo ;)

Post by: Andre Jute on December 09, 2015, 10:59:57 pm
Thorn went out of the business of beautiful handmade frames with all deliberation, and signalled that they were permanently out of it when they let the brazier go. They wouldn't have done that unless it had become either unprofitable or simply not an effective way to apply limited manpower. Why should they ever, after successfully realigning their business towards greater volume, want to go back to single custom bikes for a very limited market?

Nor is that idea of Thorn being intermediaries for customers wanting a one-off custom bike ever likely to fly. Think about it. Thorn would in effect be offering a guarantee on someone else's idea of a good frame (whereas the Thorn idea is that they have the best touring bike designer in the business, Andy Blance). That's a sure loser. But, even worse, the manhours wasted on ditzing around with a custom bike customer, and supervision of the frame maker, could soon eat up more in salary and associated overheads than anything they could conceivably charge for the service.

It would be super if it could be made to work -- I'd be a customer, willing to pay for the privilege of not having to sort the clowns from the braziers -- but there is definitely a limit to how much I would pay for the service, considering that the upcharge isn't going into the bike but into someone's pocket.

But that illustrates the key problem. With the good braziers -- say Bob Jackson -- you don't need help, you can deal direct with every chanee of achieving satisfaction; with the bad braziers (I can name some) you couldn't pay me enough to deal with them for you, and I can't see why Thorn should take a different view.

***

Those Thorn tubes aren't nameless: they're Thorn tubes, developed to Andy Blance's specifications.

tell John, as  i can't think of another way he'll get what he want's   :(
as for me i have enough new/old  Thorns to keep me going for years, i'll post some pics of work in progress sometime
it's a bit slow but i had to buy a 3hp compressor and all the kit to get up and running, had enough of aerosols

btw dn6 was made to on ones specs that doesn't mean ought to me either, Reynolds i have heard of and can't think of a reason not to want in a build, is thorn tubing better than reynolds? i don't know that either i'm not an expert in such things, i just like to ride nice bikes as often as i can


edit

just as a thought,
a simple menu system would be all they need, it wouldn't need to be a full custom build,choice of model, set sizes, choice of tubing, choice of joining said tubes( fillet, lugs, tig), choice of finish
find a frame builder who won't steal the designs, and has a half decent name, pay your money wait alloted time

yes i know you  can go elsewhere but Thorn designs have a reputation many firms pay good money to try and convince us they have but don't

From an old thread on "Sherpa tubing specs":

969 is Thorn's 4130 Cro-mo tube name.  Does anyone know what the tube thicknesses are?

Yes, 969.  Or to be precise 0.9-0.6-0.9
Now what are you going to do with that information?

Reynolds 531 is Mang-moly I believe, and 525 is the Cro-moly tubing.

hi John
the topic is never going to stay in a straight line, it is broadly going in the direction it started in
i have no more input i have said my bit
the only thing i didn't touch on is you want more bling, the only bling a Thorn needs is the stainless headbadge that they ditched, bad move, who wouldn't pay an extra few quid to have that back, POS stick on badge  ::)

btw not sure why you posted your last comment as this has been one of the better threads in ages, and your not happy with it LOL

perhaps it should of been split again and your original post would have died

btw i agree about handmade and British i have put it in my posts in this thread, some might say Thorn have sold out and are just another boutique brand now with just a vestige of their former glory days


 i bought a xTc classic and a xTc fillet brazed frame in the Thorn sell out, why because i knew they were never going to make as good a bikes again for my needs



Hello,
I am not unhappy with the thread, just a bit miffed it strayed from my original posting.
I agree it has been a long run, praise indeed for my posting surely?
All the best,
John

Yes but they have to make money, and Thorn have chosen to occupy the niche that is the Taiwanese batch factory handbuilt touring bike (either heavy duty Sherpa/Raven/Nomad, or lighter duty ClubTour/Audax, plus a few Tandems).

If you want handbuilt in the UK, there are others who can supply that niche, but the volumes are much lower and the costs much higher (probably at least double on the price of a frameset).

They used to do more colours (most frames were available in four colours at least), but unfortunately only two colours in each model seems to be the option now, presumably for economic reasons, cost of ordering more batches, stock costs, etc.

Personally I think they have the balance between Rohloff and derailleur bikes about right just now.

As for bling, presumably most Thorn customers don't really want bling on their touring bikes.

Presumably Thorn know their market, sales figures, and customers better than the handful of us who frequent this forum.


Hello,
I agree with what Thorn are now doing!
I just do not like it and would prefer home built brazed rather than tig frames.
I actually own other brand bike (s) and whilst tig welded look more brazed and the paint rather than powder coating is fabulous.

yes and that's why made in taiwan , no name tubing, and stick in a hoff is the new mantra, easy money

Handmade bikes seem to get rarer and rarer. The increasing price of skilled workers is probably a big piece of this, plus automation keeps building better stuff at lower prices. This is a general global manufacturing trend.

The above lines are from someones posting.

My reply:- In UK there are an ever increasing number of framebuilders and there is even an annual Show in Bristol and awards!
Bespoke Show UK.

i called it no name tubing as all the older ,dare i say proper Thorns very proudly told you of the reynolds tubes used in the frame,

i have to be really careful as i really am not trying to denigrate the new Thorns,
But John has talked about better/nicer/more upmarket frames like they used to be.
 i'm just adding a voice that says i agree the older kit is much more desirable
a lot would probably shell out the extra to get a Thorn like you used to
if they can out source mass produced frames, then at a cost to the buyer is there no UK frame builder they could trust with their design to make them?
yes it's going to be expensive it always was but more people spend big money on their dream bike than ever before
they even spend it on disposable carbon bikes  ;)


Hear hear!

I would have much preferred a hand-built, Australian-made, crafted timber custom dining setting for  our family room. We ended up with a Chinese timber setting, crafted from our very own Victorian Mountain-ash timber. It was the $5,000-6,000 price tag that sent us away from local furniture makers.

The Chinese setting was $800, even with all the shipping.

It's all about manufacturing cost versus quality.

Cheap/good/light - choose any two.

+1 for il padrone's summary of the arithmetic.

I can offer several examples from my own recent experience:

1)   Researching the various options for a Rohloff-based touring bike a couple of years ago, I looked into buying a custom bike from True North Cycles, a small and respected manufacturer near Toronto. One of their custom machines would have cost me about C$6,000.

      I bought a Thorn Raven frameset, sourced hubs and lighting online from Europe, other components from UK and US suppliers, my LBS build the bike. Total cost was about C$4,000, ⅔ of True North's figure.

      Other price points were a complete Raven from SJSC, about C$5500; and the same for a Tout Terrain from Peter White in New Hampshire.

      For me, the choice was obvious, and I would say that my Raven is very good value.  It's quality gear, but at $4,000, it's expensive. I was fortunate to be able to finance it by selling an old, restored and hence desirable motorcycle.

      A further note on the True North bikes:  They're fine-looking machines.  Earlier this year, I met a guy from Ottawa riding one -- we were both on a ferry near of all places, Auckland, NZ.  I've also been in touch with a guy who rode his across Canada this past summer. He lives a couple of hundred kms south of Ottawa, and decided to buy the True North because its maker is three hours' drive from where he lives. Reasonable enough, but for me, not enough to spend an additional $2,000. [I did learn from him, however, that there's a Rohloff repair specialist in Toronto, whose shop is a short distance from my daughter's flat  :-)  ]

2)    The arithmetic plays out in similar fashion in other examples, unrelated to Rohloff hubs.  In the past few days, I have been pricing a renewal of my ti-framed Eclipse touring bike, which I now use for (slightly) faster (if less comfortable) day rides.  First on the order of business was a set of steel forks to replace the slightly scuffed carbon forks of the Eclipse.

       I used as a reference point the Mercury 853 forks from SJSC, £240 (less VAT, plus P & P), about C$500.

       I then discovered that Velo Orange offers an entire frameset for their Pass Hunter rando bike for about C$700 (plus P & P). Thorn's product quickly became only a reference point for dimensions and weight.

       My research ended with better news still.  My LBS makes and sells their own brand of rando and cross bikes, "Steelwool". Happens that the guys had a bare set of forks in older unsold stock, and that I can get those for $100 -- painted by (read this and weep, you lot) Guiseppe Marinoni's shop in Montréal.

       The historical footnote here is that, when they first conceived and designed their Steelwool bikes 10 or 12 years ago, they priced making their frames here in Ottawa.  Well…  Home-made framesets would have cost about $1500 each; products of comparable quality from Taiwan, landed in Ottawa, about ⅓ of that.  Guess which option won out? 

        There's no mystery here. That arithmetic is the product of much larger production runs in Taiwan, depreciation of capital equipment required to make the farms and forks, and of course cheaper labour; and of under- or un-costed CO2 emissions in both production and shipping. If and when the latter are included in the final price of frames and forks, local frame makers here or in the UK, for example, might get some protection from the currently lower production costs in Taiwan.

-1 for his summary

i can go on ebay and spend £2400 on some carbon frame
i can buy a nomad ss and hoff back wheel £1500 or a full build what £2500ish for a tasty set up? (if figures are out sorry i have never looked at a nomad, as explained before, i'm in Devon all we have is 2 coasts and never ending hills between )
neither interest me in the least but what makes you think because i prefer a mech that i wouldn't spend £1500 on a pukka handmade frame set after all it's no more than your end up paying buying into a Taiwan frame and the hoff wheel

Post by: John Saxby on December 10, 2015, 06:35:25 pm
Bill, I was describing how the the arithmetic worked, and works, for me.  I don't know you, and know nothing about what you might or might not want, and/or would pay for.

For me, two things came into play, and remain.

The critical factor is that, after 10 years of headaches with the derailleurs and cassettes on my der-equipped touring bike, I wanted no part of a similarly equipped touring bike, hand built or not. (As a reference point, I could have bought a couple of well-equipped Surly LHTs for the price of my Raven. When I started thinking about the ratios and whatnot, and the prospect of missed gears on a steep climb, the onset of the familiar headache ruled out even a 'what-if?' comparison…)

The second is the absolute cost of hand built frames, no matter the drive system.  We're retired, and live on fixed incomes, which happily are adequate for our needs and a fair portion of our wants.  For things above that, like a Raven, I've been able to sell an asset.  (Ditto for the rehab of my Eclipse, now converted away from touring duty.)  In the absence of that option, I certainly wouldn't have a Rohloff-equipped bike, and equally certainly, I wouldn't be looking at touring with any enthusiasm or confidence.  Happily, the Raven gives me  loadsa both  :-)

Hi John
i'm not loaded by any means, but i have got to the stage in life that i want fewer bikes but much nicer quality, and am prepared to save/pay for it
i'm in the market probably for one last frame, it will more than likely have to be hand made as i am 100% sure on what i want a stainless xtc classic but beefed up a little for disk brakes(avid bb7's)
i'll probably strip mine down sometime and send it away to be replicated as near to original as poss
it's taken me years to hone down what i need for my locale, tried road bikes but they are useless round here, tried mtb with slicks,my sherpa as lovely as it is is a pig on hills, my klein attitude is the nearest i got to perfect for the hills but it couldn't carry anything unless i used my bob trailer  ::)
the xtc is fun to ride the hills on but i really need more brakes

If you really need discs, Bill, and you want them on a bike you already have, and you're an experienced restorer, surely it's a pretty small project on your scale of things to either have a disc brake tag fitted to the frame and repaint it, or to swap in a disc fork.

I have bike a high-end Gazelle, a first series Toulouse "vakansiefiets" (a bike a Dutchman saves for his holiday...), with a disc brake in the front and one of the older, limper Shimano roller brakes in the rear. Aside from the fact that I hate disc brakes for their tiresome demands for service and expensive pads, and their general lack of gradation (compared to my fave Magura rim hydraulics), that was a very agreeable setup because it distributed the braking effort right even in full on emergency stops. 90% of braking is done by the front wheel anyway, so you don't need a disc in the back.

 :-[ i hope i haven't given the impression i'm an experienced restorer,
it's purely for my own pleasure, i only bought the compressor and spray guns as i really enjoyed doing the xTc classic,
 i still had the xTc fillet brazed and also the other Thorn(no idea of true model if it is a model and not a custom)
i knew i would have to redo the classic sometime as i only used halfords rattle cans last time,
i figured what with all the frames and a load of my stove collection in need of painting it would be better in the long run to learn how to use proper paint and equipment, got to admit spraying is a doddle with the right kit and real paint, next is learning to use my airbrush

as for forks with a disk i have looked at the surly disc trucker forks in 26" on the sjs website and have considered getting the frame adapted, but by the time i pay to get the forks and raw steel them to match the frame,send the frame away both lots of postage to and throw, cost of labour and the disk fittings, i'd be well on the way to custom

hi Jags
my last road bike, promise not to laugh  ;) was a halfords carrera magnesium alloy jobbie with carbon forks some ritchey gear if i remember right and all shim 105 (cost a few quid so wasn't totally naff, i think merida frame)
hated the harsh ride, didn't feel safe with carbon forks, and the gearing was stupidly high, add in the hills and i didn't find it fun riding, and to me it has to be fun, unless of course your fully loaded then it's grit your teeth and stop bitching  ;)

nearly forgot i was always kicking the front wheel and that gets to be a pain

Bill the thorn audax is a crackin bike  no toe overlap, but im a midgit  little feet  ;D ;D.the carbon forks are safe as houses i hit over 60mph going down a mountain pass in spain rode it over rough tracks  all kinds terraine  fear not you wont break them.
but  go for 853 forks if you dont fancy carbon.
a light fast bike makes for easier cycling ,most of my rides are 3 to4 hours long  and i have a dodgy back i still manage to come home fresh.

i love steel bikes my son rides my old raleigh 753 and he loves it.
(he was a crackin good racer few years back,rode   carbon bikes all the time   but could not believe the ride my raileigh gave him  when he sold all his bikes.)

anyway good hunting all you need is lots and lots of money buy any frame your little heart desires  ;D ;)

i certainly do Bill if i buy another frame it had better be a tourer because the doll (wife) will most defo fire me out off the house :o :o

my only hope is to win the lottery or ask sjs cycles to take a fiver a week for a  new frame some chance of that happening. ;D ;D.

I think a Rohloff may be less expensive, fair play to the lad though.

Man, what a thoroughly entertaining evening of viewing this post caused me to have, youtube took me off on all sorts of tangents.  :D

Though not a bicycle, it did start off being pedal powered:
