CeramicSpeed T45 Shimano 24mm Bottom Bracket

T45 is sometimes known as ThreadFit82.5, sometimes as the Colnago standard. This kit allows you to install Shimano and other 24mm diameter spindle cranks on your Colnago.

CeramicSpeed Bearings come installed in cups and are connected through the shell. There are 2 versions: Standard and Coated Bearings. Both have super round CeramicSpeed Balls and hardened-steel races. The CeramicSpeed Coated Bearings 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.
