Description

The BIKONE BSA Steel 29mm Spindle Bottom Bracket is designed for cyclists using SRAM DUB (29mm spindle) cranksets and seeking reliability and performance on-road and off-road. It installs on the BSA thread, compatible with frame widths from 68 to 73mm.

It incorporates Dual Cup Technology (DC Tech): two aluminium cups that perfectly align the bearings on each side of the frame, ensuring no play or unwanted noise.

Fitted with fully sealed high-quality chrome steel bearings (ABEC5/P5), it ensures smooth rotation and long service life, whatever the riding discipline.

Its T6-treated 7075 aluminium cups offer excellent mechanical strength and long-lasting durability.

Note: for SRAM DUB Wide cranksets, a DUB Wide adapter kit is required. This BSA bottom bracket supports SRAM-equipped cyclists seeking a smooth, durable drivetrain.
