Description

The BIKONE BB30-73a Steel Bottom Bracket for Shimano is an asymmetric press-fit bottom bracket designed for cyclists using Shimano (24mm spindle) cranks and seeking reliability and road performance. It fits directly into the frame cups to 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, eliminating any play or unwanted noise.

Equipped with high-quality chrome steel bearings (ABEC5/P5), it guarantees smooth rotation and good wear resistance.

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

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