Description

The BIKONE BB30-73a Ceramic Bottom Bracket for Shimano is an asymmetric press-fit bottom bracket designed for cyclists seeking maximum efficiency on the road. Compatible with Shimano (24mm spindle) cranksets, it installs directly in the frame cups using the BB30-73a standard.

It incorporates Dual Cup Technology (DC Tech): two aluminium cups that perfectly align the bearings on either side of the frame, for rotation without play or unwanted noise.

Equipped with high-quality hybrid ceramic bearings (ABEC5/P5), it offers exceptional pedalling smoothness.

Its T6-treated high-strength aluminium cups guarantee robustness and long-lasting durability.

Note: this bottom bracket is only compatible with road frames.
