T45 Bottom Bracket for SRAM GXP

Some Colnagos come with the T45 bottom bracket standard. It’s sometimes known as ThreadFit82.5, or just ThreadFit. It has an 82.5mm width and threaded sleeves. This kit allows you to install 24/22mm diameter spindle cranks from Quarq and SRAM 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 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.
