Small part, huge feel

A bottom bracket should disappear under you.

Machined for alignment

The tolerance is set after the finish.

Revolution BBs are machined aluminium — chosen for precise bearing alignment and long-term smoothness under load. The alloy housing is machined again after anodizing, so the final seat dimensions are set after the finish is applied, not before it changes them.

The result is a shell that fits the bearing correctly from the start and stays that way.

Fitment support

Not sure which shell your frame needs?

Bottom bracket standards are messy. If you know your frame model, crankset, and current BB marking, we can point you toward the right Revolution fitment before you order.

For workshop installs, the matching installation tool and go / no-go gauge help protect the housing and verify the frame shell.
