One obvious advantage of hub gears is the ability to add a chain guard and then (a) put as much lubrication as you want on the chain and (b) be able to commute in light-coloured work trousers without disasters. SJSC have a chain guard in their on-line shop but don't seem to offer to fit one to their Ravens - any thoughts?
-
You are quite right. Full chainguard/chaincase is possible with the Raven. I have one fitted to mine and it gives fantastic protection and after 1000kms of all weather travelling, the chain and sprockets are pretty well completely clean and shiny. Fantastic.
I used a Pashley chainguard which I got for about £30. It's a little bigger than I need but looks fine. You can see pictures of my Raven on this forum.
Pashely wouldn't supply me directly so I had to get the guard through an LBS. It fits very easily and very well.
-
Thorn makes a nice bash guards too. But only for some selected crank sets. In the past I’ve hit my chainring on a bumps before, but now with my lightweight aluminum chainring I’d be sure to damage it if unprotected.
The added bonus is that my trouser nolonger get durty as well, and I think it helps a little against grit hitting the chain.
Cheers,
Stijn

I used a modified Pashley Princess chainguard and got 10,000 miles on one set of cahin and sprockets (mostly on a trans-ISA trip in 1999).
I changed the chain, not because it broke, but because it was worn and I was off touring again, so didn't want to risk a chain that old.
The down-side of a full chain guard is that it takes ages to get the back wheel out if you get a flat.
-
My full chaincase adds only a few minutes to rear wheel removal. Well worth the extra effort for the protection I get to my chain and sprockets.
-
Dear Marc,
after reading your enthusiastic contribution about your chainguard and being quite unsuccesful myself when trying to get any further information about available makes and dimensions from pashleys to fit one on my raven tour. i wonder wether you could tell me the dimensions and part no. of the one you use. What size chainring and bottom bracket do you use?javascript:insertsmilie('[?]')
Thank you

The chainguard is a standard Pashley chainguard. I'm not aware of size differences. Mine is a little on the large size but it looks fine and does the job. You do need a longer bottom bracket. Mine is 118mm instead of the orginal 113mm.
My chainring is 38t but because the chaincase is large there would have been no problem accomodating a larger chainring.
As I have already said, the protection of the sprockets and chain is fantastic. After a year of regular use the parts are still gleaming and grit-free.
The chaincase adds only a few minutes to rear wheel removal and replacement but not long enough to be an issue. After you have rehearsed it 2 or 3 times it becomes very easy. The Pashely chaincase has plastic clips on it and so it is only necessary to undo 2 allen bolts at the front end of it to remove it. My chaincase uses the bottleholder fixings to secure it. The bottle holder fits on top.
-
I'm curious if anyone has any experience with the chainguard at:
http://www.noell-fahrradbau.de/specials.htm
especially with respect to fitting it to a Raven!
-
Wow! That is an interesting chainguard. I can't read the page but I'll find a transaltion soon. However, it looks a bit pricey at 95 Euros plus what I take to be about 8 Euros delivery. But ... I love a gadget ....!
-
The automatic translation isn't very good but it seems that the kit comprises the forward chainguard and the rear sprocket guard and two lengths of tube which you cut according to the length of your chain.
Brilliant. Simple. Why didn't I think of it. It must save some weight over the Pashley guard I am using and should reveal the lines of the bike a bit better.
I've contacted them asking for info in English.
I'll report back.
-
I called Germany.
The owner of the company who is called Noel seemed surprised that anyone should have heard of the chaincase. He agreed that maybe it would be useful to get an English translation of the spec.
The tubes are made of Teflon and the fore and aft cases are made of some very light special plastic which he was unable to name for me in English.
He doesn't know the weight of the system and said that maybe he would include that detail in the English spec.
The bummer is that it is only made in one size - 16 on the rear and 44 on the front.
He said that if anyone wanted to order 200 pieces in another size then he could do that size.
Finally, the only colour available at the moment is black. Presumably he could do other colours for a bulk order.
-
Looks good, though for me the 44/16 gearing would be too high. I also wonder how it would affect the adjustment on the EBB.
-
There is another similar chainguard from http://www.utopia-fahrrad.de/. I do not see it on the website, but in the downloadable .pdf catalog on page 59. My command of the German language is nonexistant, so I cannot tell if this is available as a stand-alone item or if it is compatable (or available) for different sized front chain rings.

Stumbled on a test of a new chain guard from the German producer Herbie (maker of the strongest propstands availible!) in Active Radfahren magazine:
"Still prototype, mad optics, innovative:Kettenkasten from Hebie
Hebie, German manufacturer of Radschuetzern, stands as well as chain contactor models presented us first exclusively the KK 350, a "swimming chain guard", that easily at nearly all wheels with hub circuit to install leaves itself...
The closed chain guard, according to elevation IE marketing man Dominik whip "the only cantilever complete chain protection", can without tool from four parts be plugged together and is simple with a wheel breakdown to dismount. It holds at the wheel without further framework attachment. Been suitable for chain sheets with 38 teeth in front, 18-22 teeth in the back. The chain "swims" quasi therein.
Advantage: Clothes get less, small chain care expenditure, longer durability dirty.
Whip: "test result after over 20.000 km: no wear, no noises." According to Hebie the price under 35 euro could settle down. Which would be genuinly favorable. Distribution: starting from at the end of of May.

Looks very similar to the other chain guards from Germany earlier in this thread!
Don´t know if it is superior to these, but it might be available from the British importer if they have one:

Found that Active Radfahren Mag. also reviewed the chainguard from Utopia/Nöll:
"Clever made: Closed chain protection of Utopia
(09.02.05/df) Many Radler estimate hub circuits, because they are totally enclosed and nearly maintenance-free. Wheel manufacturers Utopia offer now for its models as well as wheels with Rohloff circuit, to Shimano new inter 8 or Sram 7-Gang hub transmission a round around chain protection. A similar system gibt's also with Noell. Since Utopias "Country" protection straight runs in actively the wheel driving test, here to it...
A good chain protection possesses has many advantages: One does not have to make oneself concerns around dirty clothes. There is no quietschende chain after rain travels. With good Kettenschuetzern - like the presented Utopia Country - no noises arise with impact holes and rough plaster. And there is hardly still chain changes necessarily, because your chain keeps substantially longer.
Thus the Country functions: With the Country the chain is led surely and flexibly in PE pipes. These move with the chain and prevent noises, which develop in the housings.
The two plastic housings, which enclose the gear rims in front and in the back, are flexibly connected by bellows with the PE pipes. The bellows prevent that vibrations of the chain will transfer to the plastic housing. If the chain lengthens itself, one can pull the impeller calmly to the rear, PE of pipes has enough reserve.
The developing friction in PE pipes is not of importance. This principle became generally accepted with couch wheels, where the chains themselves are led with competitions by such pipes. The pipes have to be replaced long-lived and in the case of loss simply in the workshop.
Also the disassembly of the rear wheel is not a problem. One must unscrew in addition only a small cross-notched screw on the rear part chain protection and draw then the now free part of the rear chain protection diagonally downward, finished. Now the rear wheel can be dismantled in such a way, as one is used to it.
To which wheels does the Country fit? Naturally to all Utopia of bicycles, which are maximally 5 years old. With other bicycle makes the bicycle specialist dealer must examine whether the chain protection fits. It is important that the crank a tooth chain sheet possesses 38 or 44 -. crank and chain sheet must be bent. No screwed chain sheets, only pressed crank/chain sheet connection
Importantly: The Innelager must permit it that chain protection eyeglasses can be used. There are camp (e.g. of Shimano) not at the outside edge the frameworks pushes away separates is inward screwed. These camp cartridges do not fit.
The Kettenchutz fits in D rule with almost all wheels with Rohloff speed stroke 14 course transmission hub or with wheels with Shimano inter 8 (the new 8-Gang hub!!) as well as to wheels with Sram Spectro 7-Gg circuit.
With Rohloff only with more easily, middle and strong translation, in the back at least 16 tooth with the Sram 7-Gang with easier, strong and middle translation with in the back 18 and 22 tooth pinions. Take up rear pinion simply times with Utopia contact concerning 8-Gang Shimano.
As chain only narrow chain (1/2 x 3/32) may be used. Utopia uses the Wippermann Connex chain with left. With simple chains, which are sharp edged, the PE pipe can be damaged in the long term.
For re-tooling to other wheels Utopia means: "the experiences of the first two years show that in most cases the chain protection fits also to other wheels. Problems result always then if wrong cranks, gear rims or chains are used.
Which versions are there? There are two colors: Silver and black. Dreii remarks: For Rohloff speed stroke, Shimano Inter-8 as well as Sram 7-Gang. Two sizes: For chain sheet with 38 teeth. Or for chain sheet with 44 teeth
The Country is flexibly adaptable to Hinterbauten of different lengths. It fits also with Rohloff with rope box or disc brake. With Sram 7-Gang and Shimano Inter-8 is no matter it whether resignation or free-wheel.
wheel driving recommends actively to let the Country in a framework place install. We can give however no guarantee that the Country to all bicycle types in the market are fits! Price: Utopia Country chain protection 139 euro. More information over Utopia and Noell:

The CTC's magazine,"Cycle" had an article in the June/July issue about the Hesling Excelle chaincase sold here by Cambridge Dutchbike. It qot quite a good review and cost about £20. More info is apparantly available by phone on 00051 20 612 3919 or e-mail on enquiries@dutchbike.co.uk. I haven't tried to contact them yet, but I probably will shortly. I'm off this week to Thorns to have a look at Ravens!
-
http://www.dutchbike.co.uk/Bikes/xtrabigbike.htmhttp://
This link shows a bike with the Hesling Excelle chaincase.
Compared with the other chaincases mentioned in previous posts on this thread, the Hesling appears to be quite 'traditional' and perhaps heavier than the others.
Hope the link works

I bought one of these from Cambridge Dutchbikes. They were very helpful and emailed pictures, measurements etc. I decided that for £20 I'd take a chance....so now I have a chaincase in the shed! From what I remember of my attempt the main problem was that the chain sits further out from the hub than most other hub gears so the guard fouls the seat and chain stays, also the standard crank supplied with the Adventure tour is actually a double so the extra set of bolt holes would need cutting off to get it to fit. CD did offer to take the case back and give a refund but it had gained a few scratches by then and hardly seemed worthwhile.
I did discuss chaimnmcases with Robin before buying one. He informed me that a number of owners were interested and they may at some point produce their own. I sent him the link for the utopia-farrad one but he didn't think much of it.
Anyone want to buy a sightly marked chaincase?
-
See my other posts and pictures of my Raven Sports with full chaincase. Yes, you do have to fit a fifferent bottom bracket. Mine has a 118mm BB instead of the standard 113mm - but my chaincase was fitted from new so I didn't have to replace the BB. However, since then I found a very good condition Royce titanium 118mm BB which fitted for a bit of expereince. - Very easy to do.
You will need a slightly longer BB in order to fit a full chaincase.
-
I have just bought a Pashley chain guard, but it seems that the chainset supplied with the bike is too fat (in both directions) to fit the chainguard. I have a Thorn triple chainset with only the outer ring fitted, but the tapered arms are too chunky, and the width across the redundant bolt fittings is too great to fit inside the guard. It seems that I will need to buy a different chainset to fit. Has anyone else had this problem, or found a way around it?[?]
-
Yes, see my post from 16th march! I did consider grinding the redundant fittings down but as I also needed to modify the BB mounting bracket to move the guard further out and melt the back and around the seat stay it was all getting a bit too bodgy so I abandoned it!
-
Alex Wetmore has a good article with pictures on how to fit a Pashley Chaincase to a singlespeed bike:

Good luck and have a Great Summer!!!

I had a chance to examen the Noll, mentioned above, in Zurich. Acoording to the shop keeper it only fitted on 44 chain ring 16 sprocket. It looked to me like the guard would cause quite a bit of friction because it makes the chainring run in a slot which seals the chain from the elements. Also the chain runs through two plastic tubes which it will rub against. Also the metal brackets at the back didn't look very solid. It needs to be fitted behind the cap of the bottom bracket. I'm not yet sure this will work with an rotating eccentric BB like the ones on the Thorn frames.
As for the more conventional Guards, I'm not in favour of them anymore, I had them on all my bikes from the age of 10. The rateling of the chain agianst the plastic of the guard has put me off from fitting one on my Raven tour. I now use a dry lub on my chain which doesn't attract much dust, but I don't know if it will give me 10,000Mls, like Marc above
-
If you are using/able to get older Shimano XT cranks (the original Octalink ones, M751 or M752), it is possible to make a good job of fitting a chainring guard. This clearly doesn't enclose the chain like a chain case but is a lot better than a fully exposed chain.
My Raven tour is now fitted with M752 cranks and a 'new' LX Octalink bottom bracket in 121mm length. The 113mm length gives a 47.5mm chainline (on the middle ring position), so the chainring fitted on the outer position is about 7.5mm further out or 55mm. Near enough to perfect chainline for the Rohloff hub. The 118 B/B would give 50mm chainline, which is what I'm using on the tandem. The 44t Thorn chainring has to be opened out by a friend with a lathe because it's made to fit the outer position of the spider, with a 88mm hole. The middle position, although it uses the same bolt holes, needs a 90mm hole to fit the spigot. But then the outer position is free for fittng a nice black Thorn bash guard. No spacers required and very neat. Obviously a 50mm chain line is about 4mm out, but this is only half the width of the chain and a lot better than many derailleurs are runnning much of the time.
However, the LX 121 bottom bracket has the extra 3mm all on the drive side. Must be because the current LX cranks push further on to the axle than the old XT. So I've got a 53mm chainline and a chainring guard fitted as described above on the solo.
Obviously the 'Q' factor must be fairly high, but I don't notice the difference personally.
-
I contacted thourn to ask which of the chainguards mentioned in this thread they recommended.
ie. Pashley
Noell
Utopia
Herbie
Hesling Excelle
They replied that the utopia is the best of a bad bunch.
Yikes!
I contacted Utopia and they want €150 for the chain guard incl. delivery. I cannot afford this much, especially for an ok product. Incidentally they had never heard of thorn before and were very interested. Both started in the same year. I got the impression that they were a bit jealous of the low prices but their bikes do come with mudguards, racks, chainguards etc included.
Marcg paid only £30 for his pashley guard and seems happy so I have checked with Thorn to see if there are any issues with my particular bike.
Marc, are you still content?
Does anyone know of any other alternatives in the lower price range?
Anthony
-
I contacted thorn to ask whether the pashley guard would be ok.
They say that they do not like pashley products in general but that they will receive some Hesling guards in three weeks for testing and that I should write back then to ask about these.
If these are also too expensive or no good I think I will buy a pashley guard anyway, even if it is only while I am saving up for a better guard and hoping that the prices drop / other, better guards become available. Even if pashley do make poor quality products I do not think that there is much that can go wrong with a chainguard as long as it fits my bike. One problem is that they have not replied to my e-mail.
Marc, did you ring them to get them to send you your guard?
Anthony
-
Help me out here. Why would anyone want to fit a chain guard to a tourer? Sure, if you're commuting in normal trousers, you'd want to protect the cuffs, but you can do that with a pair of of reflective ankle bands.
One alternative I saw at the Cycle Show was actually fitted to the step-through Raven. It's not a fully-enclosed chain guard, but it does seem to be a good compromise, preventing major-league cuff shredding.
-
The main reason for me is to protect the chain, not myself.
I want to keep salt, water, grit etc. off the chain to protect it and prolong its life and the time between cleaning and lubing.
According to jobst brandt commercial grinding powder is made from oil and sand which is why chains can wear so quickly.
I had hoped for much longer chain life with my adventure tour but have found that the chain wears just as quickly. The only plus is that I can adjust the slack using the rotating bottom bracket.
A fully enclosed chain guard would allow me to put on a really sticky lube and not need to worry about it washing off or becoming contaminated.

-
I'm with Ratty and others. I'd like a chaincase to protect the chain, not my pants.

Chainguard update:
We've just tested the HEBIE Chainglider...
The guard rubs on the chainring. The chain rubs on the "chain pipes" and the sprocket. This all adds up to a great deal of friction and so lack of efficiency. We think it would be easier and quieter riding with a rusty chain!
Currently the Chainglider is only available for a 38 tooth ring and 18-22t sprocket, although they do have plans to make more sizes.
We'll keep looking at chainguards... If there's a design you've seen and like let us know and we will test it.

Well your spanking new CHAINGLIDER won't work on that gearhub without rubbing will it? I mean the CHAINGLIDER model you're using is designed for a 7 or 8 geared hub, like Nexus for instance, and not for a Rohloff Speedhub. The Speedhub's sprocket is far too small for the CHIANGLIDER model in your picture. I'm suprised in fact that you got the thing on and working at all. And as for the rusty chain I for one am far happier with my CHAINGLIDER then having a rusty chain sqeaking away and getting stiffer and stiffer.
-
Andrew, would it not be viable for you guys to make your own chain guards?
Preferably something that would take up to a 52 or so in the front and up to a 24 in the rear. Making it as flexible as possible, to fit other bikes, perhaps?. Is such a guard even possible?
I think the benefits a chain guard brings, far outweigh the negatives(aesthetics), I'm sure touring folk would prefer the less frequent chain replacement from reduced wear [:D]

Rusty Chains ???!!! Is someone having a laugh? Who gets rusty chains? Shame on you. Spray them with Motorcycle Chain-Lube. It spays on using a solvent, the solvent evaporates and leaves the lubricant in all the right places.
Oily Trousers??!!! Use Bike-clips, I believe they have been available for a few centuries. Socks can also be used to tuck trousers into.
Come on guys, this cycling lark isn't a new thing, I can account for at least 40 years of well-lubricated chains withough getting it onto my trousers. Is all this faffing about with chain-guards worth the aggro and making your bike look like a Butcher's bike ?
Chain-Guards??!!! Please let's stop being silly. Remove them at once and donate them to the Village Nurse's bike.
-
Hi freddered
I agree there is no reason to get a rusty chain and no I don't get oily trousers. However I still might be interest in a fully enclosed chain guard. The thought of never needing to clean my chain again is appealing and so is the 10,000+ mile chain life expectancy.
I am undecided though as I feel a chain guard would make bike more difficulty to maintain plus it is one more thing to go wrong.
-
More on chain guards.
Herbie have brought out a new model. The 'Herbie chainglider 350 42' specifically designed for the Rohloff Speedhub. It is compatible with 42*15,42*16 and 42*17.
Andrew is there any chance you could test the new model?
The Herbie web site is now also in English! Click me (http://"http://www.hebie.de/html/en/start_de.php5")
-
Any news on this? I have been holding off buying a Thorn until they supply their own chainguard, made to their own exacting standards. OK, so there are a few oily-fingered old die-hards who love the smell of de-greaser (fred), but there are also plenty of people who just want their bike to work. There is clearly plenty of demand out there, so come on Thorn, give us the long-life and hassle-free transmission that a Rohloff hub makes possible!

I have had the new version of the Hebie chain guard for three weeks now. I had to buy a new front chain ring as my original one was to large, also the chain ring must not be thicker than 3.5 mm. Once I had the correct chain ring in place, fitting the guard was very simple.
Does it cause friction? Well, somewhat. However, I bought the chain guard mainly for winter use, with sleet, slush and salt heavily degrading the life time of my chain. Now, the chain is clean all the time! The noise generated by the friction is far less than the noise generated by the Rohloff, and I think the friction itself is neglible.
One nice feature: You can oil the chain through a small whole at the top of the chain guard, no need to open up to reach the chain.
So, after this short test period I am quite happy with it. Recommended!
-
Any news on this?
There were issues with the Hebie Chainglider, it abraded the Speedhub and cut a groove into it with the time. But it is solved now.
-
I tried one for a week a little while ago. I found it added about 5% to 10% to my normal commute times. I also thought it would muffle any sounds coming out of the chain that would tell me it was time to oil it again. On the plus side it did keep the chain clean and wasn't too hard to put on and take off. In the end I took it off because I thought it slowed me down too much.
-
Hi all, I'm new here, my first Rohloff has just been shipped on its way to me - hopefully I can ride it for the first time in a week or two. On my request, I had a Hebie chainglider added. I am unfamiliar with enclosed chains, how should I lube it? Dry Teflon-based lube, or some light oil?
-
Hi blazius,
Welcome to the forum,
I don't (currently) use a chain guard, however if I did I would be using a 'wet' lube. The chain guard will keep dust away from the chain and therefore the is no reason to use a dry lube. My personal preference is Rohloff chain oil.
Could you do a review of you chain guard in a few weeks time? - I would be very interested in you experiences with it - thanks.
Have a blast on your new bike!

First impressions after using my new Steppenwolf Tao Light Rohloff with a Hebie Chainglider (the model designed for Speedhubs):
It works like charm! The Chainglider does not cause any detectable resistance when pedalling, neither on the road or in the workshop. You can hear a very slight "swoosh" from the chain gliding against its cover, but this is hardly detectable amidst the noise of the new Speedhub. ;) I have not tried it in muddy conditions yet, but the chain stays dry after hosing down the bike.
The Chainglider is made of 5 plastic parts which seem to be quite rugged. There are small drain holes on the bottom if you should get any liquids inside it (the largest gap is a few mm where it passes between the sprocket and the hub shell).
The Chainglider is very easy do take off and put on the bike. Mine did not come with an instruction book, but on the first try I was able to take it off in less than one minute on the first try, and reattach it in less time. With some experience I guess it is possible to remove or refit it in 20-30 seconds. The only tricky point is centering the rear part over the sprocket, if this is in the wrong place you'll get a "clacking" sound and the Chainglider will start vibrating (it does not seem to be harmful, but will probably cause excessive wear and some slight resistance). This gets easy after a few tries.
Some pictures of the assembly process are attached below.
The short story: The Chainglider seems to be a very nice addition to any internal hub gear (or single speed) bike. I expect it to reduce the need to clean and relubricate the chain to once every one or the months (or even less?) for a bike used in daily, urban commuter use.

The Chainglider is an extra part, which is mounted onto a bicycle. Therefore we have no influence on possible damages on other parts the bike.

Since October 2006, Hebie has revised their design so that it will not damage the Rohloff hub shell: http://www.hebie.de/pdf/hinweis_CG_heckteil.pdf

well I have just bought the rohloff specific chainglider and will be fitting it to my new sterling when it arrives. I'll try and post some pictures of the hub clearance as well as fitting.
Edit: added words to turn it into a real sentence
-
What's the HEBIE CHAINGLIDER problem?
I guess it's the possibility of getting grinding marks on the hub shell. Because the HEBIE is a "swimming" part - not fixed with screws.
So the only recommendation is to check the hub shell from time to time.

In my installation (with the modified version), the Chainglider rests on the chain, not on the hub shell. I do not think it would be possible for the glider to cause any wear on the hub.

Tried installing the chainglider last nite, and can confirm that the standard Thorn chainring is too wide. while it can be fitted, its too tight to realiticaly be used. Crank turns but with a sizable increase in resistance when fully cliped together
-
Thanks Rontana,
That is very interesting info. Any idea what the max width would be? I have being thinking about adding one of these to my Wife's bike.
Thanks again

torel mentioned earlier that the chainring should't be thicker than 3.5mm, and the info I found on Hebies site indicates that 3mm is the maximum.
Which leaves me with the question of where do I find a thin replacement chainring thats a suitible drop in replacement for the 42T 110 BCD ring that came with my sterling.
-
Rontana,
Surly do a 42T 110BCD ring. Surly rings are made of Steel rather than Ali. So you are looking at a chainring that will probably do 100,000 miles (as you will be running it inside a Hebie). I believe it is 2.1mm thick but you would need to check.

After a bit of searching and general confusement at my local bike shop I managed to obtain one of those surly steel chainrings and can confirm that it does fit within the chainglider with even a bit of free wiggle room.
Fitted the chainglider with the new chainring, and it doesnt add all that much resistance once everything is oiled up well (using the rohloff chain oil) havent had the chance to do a propper ride with it yet, will post an update and photos once I've done a decent number of miles on it

Looks like everyone has had their fill of this topic so is there any way one of your admin bods could make it 'un-sticky'?
I'm sure there are far more important and pressing issues that need to find their way to the top of the index, not least 'discussions' about how rubbish the weather is, etc etc....!

Done
