I see that in preparation for my project of late that the most difficult item to figure out is the whole Campy bottom bracket spindle issue. There is some talk of thick thin cups, and then spindle measurements which can't actually be measured anywhere. Also there is the issue of spindle taper which may or may not cause the crank to sit out too far or to touch the chainstays. The guy who is supplying me with these parts has the parts of two or three campy equiped bikes in one bag. The brakes are easy, as is the headset and the crank and the derailleurs and the seatpost, stem etc., but the bottom bracket looks tricky. Assuming Italian threading and a known bb shell width, how will I know which spindle goes with which cups? If I understand correctly Campy used two different ball bearing sizes to add to the mix!?!
