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
