Looking at all the alfine bikes around at the moment, most of the MTB ones have 32/34T upfront, however the shimano alfine chainset comes with 39/45T. Is this simply a difference between intended usages?
I'm unsure of the ranges I would get with both combinations. For a Roadrat, should I get a 39T ? It's going to be used in a flat city (Manchester) but I will take it out into the peaks occasionally.
