Campagnolo Centaur CT crankset - which BB?
 

Hi everybody! As a newbie I need some help:
I just bought a Centaur CT (50/36 t.) crankset and front derailleur to upgrade my working bike (700C wheels) because I was not happy with the mtb triple it came with. Does anyone here know which bottom bracket length I need for installing them on my BSA (68 mm) threaded frame?

111mm for most downtube diameters. bike tires direct has the lowest price I could find for that BB.

mtb/road
 

if you are trying to put a road crank on a mtb, you could run into fit issues?
73mm bottom bracket?
chainstay clearance?
