CeramicSpeed T47/86 Bottom Bracket

T47 - 30mm

T47 is a standard created by custom frame builders. It’s threaded, has an inner diameter of 47mm, and is 86mm wide. It has the design benefits of being oversized and wide, but also the practical benefits of threads.

This kit pairs those bb’s with 30mm spindle cranks. The cups have CeramicSpeed bearings pressed in. There are two bearing options. The Standard Bearing has CeramicSpeed Balls and hardened-steel races. The Coated Bearing has the same balls running on a 3-micron thick coating placed on top of those hardened-steel races for greater durability and less friction still.

This BB is compatible with 86mm frames, and also compatible with TREK T47 85.5mm wide frames.

T47 - Shimano / Hollowtech II

T47 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.

It's compatible with 86mm wide frames, and also compatible with TREK T47 85.5mm wide frames.

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.
