Ill start off by pointing out Im already confused, but that isnt necessarily a secret around here ...
Seems rohloff want a 54mm chainline, and that seems freaking wide to me. So how do you get it?
Ordinarily if you had a road double you would use a 108mm(?) bb ... and guessing ... a 46mm outer with a 41mm inner? You can get the BB in 108/113/118mm graduations.
Also, to add further complications, I probably want a 39 - 42t chainring, and only a single at that ... I can swap the inner to the outer if I want? There is a fair bit of choice around 130BCD/5-arm, you can get most of the way between 38-56t if you can swap which side the ring fits?
So I should get a 118mm BB, that would give me a 51mm ring on the inner, or 56 on the outer, not a 113mm BB, as it would only give me 51mm on the outer, or worse, 46mm on the inner?
All these numbers have been possibly misinterpreted from Sheldon Brown's site, but we can safely say it isnt his fault.
