Description

The BIKONE T47 External (68mm) Steel Bottom Bracket with 29mm Spindle is a threaded bottom bracket designed for cyclists using SRAM DUB (29mm spindle) cranks, seeking reliability and performance both on the road and off-road. Its cups fit outside the frame, on the T47 threaded 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 high-strength T6-treated aluminium cups ensure robustness and longevity.

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