T47/86 30mm Bottom Bracket Gravel

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. The cups come with CeramicSpeed Bearings installed, coated bearings and hardened-steel races for longer life and less bearing drag.

Technical Data

With the benefits of both oversized shells and the tight fit of threading, T47 has the best of both worlds. These cups and bearings make it possible to run stiff and light 30mm spindle cranks, like those from Rotor and FSA?s 386EVO standard.

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