i've got my hands on a nice new UN72 BB, BUT rather than being 113-68 it is 115-68 (wrong ordering , already got it out of the packet and they don't have a 113 so can't send it back) - so will 1mm more axle on the driveside really make any difference with 8spd? i Know it's not ideal and i can't run extremes of gears (not that i should anyway)
someone please tell me it's okay?!
