Ceramicspeed T47 Coated Bottom Bracket

The Ceramicspeed T47 Coated Bottom Bracket is a newer bottom bracket shell design, utilizing the oversized interface of PF30 and EVO386, but with the benefit and peace of mind of a threaded interface.

This bottom bracket allows you to install Shimano and other 24mm diameter thru-axle cranks into a T47 shell.

There are 2 versions: Standard and Coated Bearings. CeramicSpeed Bearings come installed in cups and are connected through the shell. 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.
