Description

The BIKONE T47a (Asymmetric) Steel 30mm Spindle Bottom Bracket is a threaded bottom bracket designed for cyclists using 30mm (BB30) cranksets and seeking reliability and performance on-road and off-road. Its asymmetric design compensates for the crankset's natural offset for optimal fitting.

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

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

Its T6-treated 7075 aluminium cups ensure strength and long-term durability.

This bottom bracket is installed with a standard T45/T47 wrench, for easier fitting and maintenance.
