Description

The BIKONE T47a (Asymmetric) Steel 24mm Spindle Bottom Bracket is a threaded bottom bracket designed for cyclists using Shimano (24mm spindle) cranksets, seeking reliability and performance on both road and off-road terrain. Its asymmetric design compensates for the crankset's natural offset for optimal installation.

It incorporates Dual Cup Technology (DC Tech): two aluminium cups that perfectly align the bearings on each side of the frame, eliminating any play or unwanted noise.

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

Its T6-treated 7075 aluminium cups, made from high-strength aerospace-grade aluminium, ensure robustness and longevity.

This bottom bracket is installed with a standard T45/T47 wrench, without any specific tool, for easier maintenance.
