The SRAM DUB BSA Bottom Bracket is an English-threaded bottom bracket built for SRAM DUB cranksets. It uses the DUB interface to bring the crankarm, chainring, spindle and bottom bracket together around one common system, making it a practical choice when replacing a worn unit or building a new bike with a DUB drivetrain.
Inside, sealed cartridge bearings support smooth, consistent crank rotation, while the aluminium cups keep the assembly light and durable. Gutter Seal Technology helps limit the entry of water, dirt and other contaminants, making this a sensible choice for riders who expect their bike to see varied weather and regular off-road use.
Compatibility is the key detail: this bottom bracket is for BSA / English-threaded shells and SRAM DUB cranks with a 28.99 mm spindle. It supports a wide range of shell widths, crankset types and chainline configurations, provided the correct spacers are used. For a BSA 68 mm MTB shell, the specified spacer arrangement is important for correct crank spacing and chainline. Installation requires a 12-notch external bottom bracket tool, with the drive-side cup using reverse threading.
A good fit for anyone replacing a worn bottom bracket or fitting a SRAM DUB crankset to a BSA-threaded road, MTB, gravel, fat-bike or downhill frame.
