More Information

The Revolution Bottom Bracket Series is engineered for drivetrain efficiency, precise bearing alignment and long-term durability. Every unit is CNC-machined from 6061-T6 aluminium and fitted with premium NTN precision bearings for smooth, reliable performance on road, gravel and performance bikes.

The T47 version uses a precision-machined two-piece aluminium shell that keeps both bearings perfectly aligned, with a specially narrowed centre section to improve frame compatibility. The BSA version uses a threaded two-piece shell, and the BB86 version a one-piece press-fit shell for simple installation.

Every Revolution bottom bracket is equipped with NTN LLB sealed bearings for smoothness, durability and weather resistance. The bearings are fully replaceable with standard bearing tools, so the bottom bracket can keep running for years without replacing the whole unit.
