The Revolution T47 BB provides the ultimate in threaded bottom bracket performance.


A precision-machined custom two-piece full Aluminium 6061-T6 shell enforces the alignment between the two halves for impeccable smoothness.

A specially-narrowed neck helps to provide clearance for internal frame fittings and cables, improving the compatibility with more frames.

We use top-grade NTN 6806 LLB precision steel bearings for durability, reliability, and smoothness. Each bearing can be removed and replaced using standard bearing tools, allowing the bottom bracket to be used for a long lifetime.
