Description

The BIKONE T47 External (68mm) Ceramic Bottom Bracket for 29mm Spindle is a threaded bottom bracket designed for cyclists using SRAM DUB cranks (29mm spindle) who want maximum efficiency on the road and off-road. Its cups sit outside the frame and fit 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, for rotation without play or unwanted noise.

Equipped with high-quality hybrid ceramic bearings (ABEC5/P5), it offers exceptional pedalling smoothness.

Its high-strength T6-treated aluminium cups ensure durability and a long service life.

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