SRAM DUB PF30 Road Wide Bottom Bracket

With the SRAM DUB Road Wide bottom bracket for a case width of 68/73 mm, you can combine your PF30 gravel frame with a wider crank.

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 for the use of wider tyres, e.g. in gravel applications. The DUB technology offers you the perfect compromise between large bearings and axle stiffness.

Technologies

DUB – The unit of the crankshaft and 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 the chainring, crank, shaft and bottom bracket that is decisive for better drivetrain performance.
