Oversized cups for worn shells

Bottom bracket shells can grow over time through manufacturing tolerance and long-term wear. Oversized cups restore a secure fit in an enlarged shell and usually cure the creak.

Ninja thread-together design

The alloy shell extends through the frame so the left and right sides thread together, locking frame, crankset and bottom bracket into one unit. That adds stiffness and stops the movement that makes press-fit bottom brackets creak.

Fusion construction

Fusion construction wraps the alloy bearing housing in a nylon composite. The composite can be machined for a snug fit in the frame, while the bearings sit on a solid alloy platform for a longer life.

X-Seal protection

TOKEN's X-Seal technology keeps dirt and water out of the bearings with very little added friction, so the bottom bracket keeps spinning freely in bad conditions.

Compatibility & fit

Frame: BB86 / BB89.5 / BB92 (41 mm x 86.5 / 89.5 / 92). Crankset: Shimano 24 mm spindle.

Bottom bracket installation is a separate workshop service and isn't included in the price. Our workshop can fit it with the correct tooling and check the shell before it goes in.
