What judges the BB length?
I think the crankset does. I believe Truvativ said I need a 113mm for my Stylo Team 04's. That was all fine but now that I have a schwinn homegrown frame things are not so smooth. It still runs but there is very tight clearance between driveside crankarm and chainstay, I mean like 3mm max. Probably more like 2, and when im clipped in and applying load it flexes, actually hitting the chainstay protector. Im thinking that if my cranks were more spread apart may be by 5mm it would not do this. So is there anything I can do? Would a 118 cause issues
