Sram Bottom bracket Dub Bb386 Road

The new SRAM DUB™ crankset series has a simple task: connect your cranks and protect the smooth and sustainable application of power to your drivetrain. To enable this singular focus, we designed the DUB™ spindle to be the only true unifying component. An oversized spindle to work on all crankset standards. For better compatibility with the crankset. For better protection from the elements. For longer lasting performance. To be stronger, smoother and simpler. Now back to racing.

The relationship between the crankset axle and bearing is at the heart of DUB™ technology. It's where stiffness meets durability. We went beyond conventional thinking and simplified everything - better integrating the relationship between the chainring, crank, axle and bottom bracket. It's this approach to developing a complete system that means better drivetrain performance.
