Description

The BIKONE T47a (Asymmetric) Steel 29mm Spindle Bottom Bracket is a threaded bottom bracket designed for cyclists using SRAM DUB (29mm spindle) 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 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 7075 aluminium cups ensure strength and long-term durability.

Note: for SRAM DUB Wide cranks, a DUB Wide adapter kit is required. This bottom bracket is installed with a standard T45/T47 wrench.
