Could someone comment on the Bottom Bracket issue with Coust frame? I'm going to run my current Middleburn RS7 Pro Trials crankset on it with 22t chainring (so that I can move fast enough from spot to spot). Will a 127.5mm Shimano XT BB spindle be wide enough? Or if I upgrade to ISIS version of the crankset, would a 128mm Try-ALL BB would be ok with 22t ring? I think 20t will fit but is it a tight fit ie. can I run 22t instead?
