BB sizing
I have a crankset that was originally on a shimano square taper 68mm-113mm bottom bracket. I would like to use this crankset on a new frame whose bb shell is 73mm. My question is, should the new bottom bracket be a 73mm-113mm or a 73mm-118mm? I don't quite understand where the extra 5mm will go, just the shell, or the spindle length too. Thank you
