T45 is the Colnago standard, though it's sometimes known as ThreadFit82.5. This kit allows you to install Campagnolo and Fulcrum Ultra-Torque cranks on your ThreadFit bb Colnago.
CeramicSpeed Bearings come installed in cups and are connected through the shell. There are two versions: Standard and Coated Bearings. Both have super round CeramicSpeed Balls and hardened-steel races. The Coated have an additional attribute: a 3-micron thick metallic layer over the races. This addition makes the races harder and smoother, lowering drag and increasing life.
