I'm converting a steel mid 80's bianchi to run a Campy 10sp drivetrain. I'm going to run a Chorus double crank and and cold set the rear spacing to fit the rear dropouts for a centaur 10 speed cog. It's currently set at 126mm spacing.
Can someone tell me how to figure out what size bb I need? Or maybe someone can just tell me?
It's a italian bb shell and I was going to pick up a 70x111 veloce cartridge unit, but I thought i'd ask first before I end up with a part I can't use..
ALSo, if I later go with a compact crank can I use the same BB?
