Ceramicspeed T45 Sram GXP Bottom Bracket Cups 82.5 mm Black

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.
