This SRAM DUB Road bottom bracket allows you to add a wider crank to your BB30 gravel frame with a 68 mm over locknut dimension. The spacers create space for the crank axle and thus enlarge the chain line. This places electronically controlled AXS front derailleurs in 2×12-speed drives further outwards, which in turn allows the use of wider tyres, e.g. in gravel applications. The DUB technology offers you the perfect compromise between large bearings and axle stiffness.

DUB:
The unit of the crankshaft and the bottom bracket is the heart of the DUB technology. Stiffness meets durability. SRAM has gone a step further and made everything even easier and better. It is the system approach through the integration of chainring, crank, shaft and bottom bracket that is decisive for better drivetrain performance.
