I have upgraded my singlespeed MTB to Rohloff recently. On the SS setup I was running Nitto Albatross bars (comfort bars similar to North Road bars, 60deg swept back). I have a feeling that the back sweep of these bars is too much for a gripshift. Does anyone have sone experience with the Rohloff shifter on similar backsweep bars?
I would imagine that anything significantly more than that would put your wrists in a very awkward and uncomfortable position especially for operating the Rohloff Twistshifter.
Note that the proper, ergonomic, way to fit North Road bars is with the handgrips pointing down between fifteen and thirty degrees from horizontal, for which the upsweep and the long grip make allowance.
You bar looks like exactly the same sweep as mine. But they have 60 mm rise and the other 80 something. I would put it on that TT, no doubt. Easy hack.
Completely OT, sorry, but I couldn't help noticing your nice clean new shifter grip. Do you know of any source for the old-style triangular section grip? I don't really want to change to the new shifter type, preferring the triangular grip but I cannot seem to find any at any on-line stores.
Cheers, Pete
... why on Earth did they design the twist shifter with cables entering the shifter at 90 degree angle? Why not design them to enter from the side, so that your cables run nicely along the bars without bends and loops (like all other derailleur shifters are made)?You can fit v-brake cable noodles to direct the cables to the side of the rotary shifter. This strategy works nicely in a variety of applications including on bar-end (adapter) mounting of the Rohoff shifter. :)
Why on Earth did they design the twist shifter with cables entering the shifter at 90 degree angle? <snip> Herr Rohloff’s logic evades me on this one.The only "Logical" reason that I can think of is the friction induced through a tight bend in the cable at the shifter, although given they are fine on a Raven Twin (optimal routing ??? ) that may not be the case. As Dan said you could play with V-Brake Noodles to achieve a similar result. That solution probably works because it's not an extreme bend.
Seriously though, why on Earth did they design the twist shifter with cables entering the shifter at 90 degree angle? Why not design them to enter from the side, so that your cables run nicely along the bars without bends and loops (like all other derailleur shifters are made)? Herr Rohloff’s logic evades me on this one.Rohloff originally expected the main market to be MTB users who wanted an alternative to a relatively fragile derailleur system and didn't anticipate users having bars with a high angle of sweep-back.
I agree that avoiding unnecessary friction will be the key and I don't think it has to be that tight a bend. There's no point comparing it to a derailleur shifter as apart from both changing gear there's very little similarity. The ease of use and maintenance comes from the lack of shifter indexing, which in turn requires more cable pull, which increases what friction will be felt. There's always the third party options, like the Gebla Rohbox which adds some element of indexing to the shift box, or the Cinq5 which I like the look of, but not for £300! Did the hydraulic system touted a few years ago ever make it into production? Or what about electric, is that an aftermarket item yet?Why on Earth did they design the twist shifter with cables entering the shifter at 90 degree angle? <snip> Herr Rohloff’s logic evades me on this one.The only "Logical" reason that I can think of is the friction induced through a tight bend in the cable at the shifter,

...here is how Pinion updated their shifter to solve the issue I was talking about...<nods> The net effect is essentially the same as using v-brake noodles at the shifter. For some photos showing such a setup, see...
