CeramicSpeed T47/68 Outboard Bottom Bracket for Shimano

The T47 bottom bracket shell uses the oversized interface of PF30 and EVO386, but offers the advantages and reliability of a threaded interface. T47/68 positions the bearings outside the frame width and is compatible with 68mm wide T47 outboard frame designs.

T47 is a standard developed by individual frame builders. It features a thread, an inner diameter of 47mm, and is 68mm wide. The design combines the advantages of an oversized and wide construction with the practical benefits of a threaded connection.

The cups have pressed-in CeramicSpeed bearings. There are two bearing options: The standard bearing features CeramicSpeed balls and hardened steel rings. The coated bearing has the same balls running on a 3-micrometer thick coating over the hardened steel rings – for higher durability and even lower friction.

This BB is compatible with 68mm frames. Installation tool: BBT-69.
