a Rohloff rider who had trouble gripping the shifter in hot weather

I've never had that problem, Matt--not here in Ontario's hot and sometimes muggy summer, nor in Queensland's very hot temps.

But, I use cycling gloves all the time, to protect me delicate Scots/Irish skin.  The gloves also let me grip the shifter in all the conditions I've encountered.

Cheers,  John

For the most part, I don't use rubber bands because I find they get hard, dry out, break easily or become sticky in short order while touring.

I do have a lot of uses for women's nylon covered hair bands, however. The covering makes them gentle on clothing (no snags on lycra shorts and jerseys that are rolled compactly for storage and held with the bands) and they work well to both keep things together in my bags as well as for compressing sacks and bags to minimum volume while touring. They're ace for holding packets of repackaged foods together as well. They come in a variety of sizes and gauges/strengths and last a long time.

Re rubber bands; I think I recall someone saying they used them around the 2 fixing bolts on the EBB.
<nods> That would be George (username: mickeg).

Best,

An interesting article on the Crazy guy site from a Rohloff rider who had trouble gripping the shifter in hot weather.
A couple of runner bands gave him extra grip.

He also mentioned a problem with the hub after less than 2,000 Km.
I've asked him to expand.

Re rubber bands; I think I recall someone saying they used them around the 2 fixing bolts on the EBB.

Any other rubber band uses on the Thorns?

...and Andre, I haven't noticed the belt picking up any oil from the hub.

That's good to know. Thanks, Bill.

...I did have a South African girlfriend. That, I would recommend.

That's even better to know. I must get one of those.

As I have mentioned before I have a Rohloff with chain drive and one with belt drive. The belt drive works as advertised, I have had no problems with it and Andre, I haven't noticed the belt picking up any oil from the hub.

However. I don't think I will do another belt drive, the difficulty is if you are going to change anything, cogs or belt wheels, its ridiculously expensive even before you consider the cost of a new belt and the new belt must be sized precisely.It just doesn't offer any huge advantage to offset those considerations.

As to South African delicacies I have little to offer, but I did have a South African girlfriend. That, I would recommend.

Saved the power bar recipe, thanks; it sounds much nicer than the foul stuff you can buy for inflated prices. The Klipdrift "at home" isn't expensive by Irish standards (for twice that much here you can get Metaxas 7-year old, a fierce Greek brandy), where everything that can be taxed is very expensive indeed, but the carriage will be more than the brandy, and customs and excise won't be amusing either, altogether several multiples of the price of the brandy. Laughed aloud at the "couple of turns of barbed wire".

A chum  was having some dried sausage made. He bought all the meat and controlled to almost nothing the amount of fat to be included and the cleaned out the guts of sheep so there should be nothing artificial in these sausages, then took all this to a butcher to be minced and fed into the sheaths according to very strict instructions, including "Don't add anything beyond this little bottle of salt and ground black pepper." The butcher, who had a suspiciously low brow and a dismissive manner, said "Yes, yes. Yes, I heard!" -- and the minute my friend's back was turned put all kinds of E-mark preservatives in the meat. Apparently he'd never heard that dried meat preserves itself. I spat out the first bite I took, which was also the first time the poor fellow discovered that all the meat and all that work, and the anticipation while the sausages were airdried in his loft, was wasted. I was really looking forward to an airdried sausage on a ride, the authentic thing, and nostalgic too from childhood rides...

Thought my digression into biltong might raise an eyebrow in Cork, Andre ;)

The salt's an issue, for sure.  There are South African emigrés/expats here in Canada, who make & sell biltong (pre-sliced, as you note), but it's crazy expensive, and a bit too--what? "refined","genteel"?--something like that.  Also, the, uh, raw material is different--too much time in feedlots for the poor critters.  (For comparable reasons, Nando's products don't make the translation very well.)

I do less canoeing now that I used to a few years ago, but sometimes for cycling tours I  still use a food dryer to make my own "jerky", flavoured with low-sodium soy & Worcester sauce and a dash of maple syrup.

Indigenous people and the coureurs de bois used to survive on pemmican, of course.

On the matter of power bars, though:  I make my own, using a recipe from Lorraine Nygaard, who used to post on crazyguy (and maybe still does?)  These are bloody good, not least 'cos you can know & control the ingredients.  Have attached that recipe, with my own notes.

Good luck finding the Klipdrift. (Here's an online supplier, BTW: https://www.bottleshop.co.za/klipdrift-premium/) I reckon you could take it by the thimbleful, or maybe just by a prolonged inhalation.  It's rarefied, and hence pricey.  Our bottle store near Groenkloof in Pretoria used to sell bottles which had a couple of turns of barbed wire around the neck. (I'm not making this up.) I didn't know if that was the retailer's adaptation, to discourage people from making a quick grab-and-dash, or the maker's, just for the hell of it.

Cheers,  J.

Rohloff Internal Hub Gears / Re: Rohloff wears out

...
One of the really cool "value added" extras Thorn includes with every new complete Rohloff-equipped bike is a 2-in-1 or 3-in-1 bottom bracket eccentric tool. ...

I was unaware of that tool.  I assumed only those of us with an S&S Nomad got a special tool.
https://www.sjscycles.co.uk/tools/thorn-s-and-s-5-in-1-spanner-wrench-special-coupling-eccentric-tool/

***

I have to remove the crank arms to get my bike into the S&S case.  Some of you might recall that I put self extractors on my square taper crank arms for my Iceland trip, thus no crank removal tool needed.  That is until one of the self extractors self extracted somewhere in the middle of Iceland.  Self extractors were a good idea, but failed in execution.

I recently bought a square taper crank arm removal tool that uses a 15mm wrench and 8mm allen wrench.  And the crankarm uses an 8mm long arm allen wrench.  No more lost self extractors for me.

I cut a short stub off of an 8mm allen wrench that I can stick through the 8mm box wrench on that Thorn S&S tool to use for removing crank arm bolts and then the 15mm wrench and 8mm stub will work on the removal tool.  Plus of course the 15mm wrench for pedal removal.

The crank tool is on the upper right, the 8mm allen wrench stub is under the inner tube rubber sleeve wrapped around the Thorn S&S wrench where it won't get lost.  Disregard the multi-tool in the photo, I cropped that photo out of a much larger one.

Rohloff Internal Hub Gears / Re: Rohloff wears out

When I true up a wheel, if there is any play in hub bearings, I certainly notice it.  The bike shop that I worked at many years ago would never have sold a bike to someone with that kind of play in the hub.  I am a little surprised that a wheel with that much play in the hub left Rodriquez shop in the first place.  Or was everything tight initially?

I am curious, was it a belt drive or chain drive?  The reason that I ask is that a belt puts more tension on the hub than a chain.  And it sounds like the failure occurred near where I would expect more stress on the hub to occur with a belt than with a chain.

You occasionally hear of a Rohloff with a serious problem soon after new, but you usually hear of skipping gears instead of total failure.  Major bummer. 

I only know one person that tours on a Rodriguez, she loves her dérailleur bike, is not a Rohloff.


The bike has a chain. 13 and 40 so the gear ratio was good as well. The wheel have been great and zero broken spokes with rim breaks.

I picked up the bike new in 2015 and that was the third large tour on the bike. That tour was a ten week tour. The reason I had called Rodriguez was that the play in the wheel was very new started the morning I called.

The real shock to me was being told all was well finish the tour and then send it in vs the failure. Also I had never heard of a loss of the ability to pedal in any gear only of the loss of some gears.

Thanks for posting.  I would have assumed a belt, not a chain drive.  And I am surprised to hear that it happened a couple years after you got it with some good distance on the bike before the problem. 

With a 40 to 13 chainring to sprocket ratio, that is a hair over 3, the ratio I use for riding around home is 2.75 and for touring 2.25.  Thus I likely put a lot more torque on my hub than you put on yours.  Sounds like you just were very unlucky with a component that was probably defective but lasted for a few years before it finally decided to go.

If you root around a bit, John, you'll find that Boeshield had bit of a vogue for spraying into bicycle frames for rust protection.

As for biltong, one of my local supermarkets sells sliced "beef jerky" as a "luxury lunch" in a 140gr packet. I haven't actually tried it, not because I look down on sliced biltong (I do -- well-bred people offer you their stick of biltong, which they made themselves, and their pocket knife to slice your own, and intelligent conversation to illuminate the social occasion), but because it has more salt than is good for my health.

However, since sliced biltong is in Aldi here (hung on the sandwich shelf), I suspect it will be in Aldi in the UK too, and tourer and longrange day-trippers might like to try it: at least it will taste better than those wretched power bars (their makers add evil tastes to force you to grasp how good their product is -- the fouler it tastes, the better it is for you) and biltong, which one chews for a long time, is instant energy and protein too. It's the emergency saddlebag food of the men of the two small republics who almost beat the British Empire at the peak of its power in the Anglo-Boer War of 1899-1902.

First I hear of Klipdrift brandy but I'll put it on the list of stuff I want sent from South Africa, just in case one day my cardiologist relents and lets me drink again.
