Movimento centrale SRAM DUB ROAD

The SRAM DUB™ bottom bracket series has a simple task: it connects your crank arms and ensures smooth, long-lasting power transfer to your drivetrain. To enable this focus, we designed the DUB™ axle as a single, truly unified component. One oversized axle for all bottom brackets. For better crank arm compatibility. For better protection from the elements. For longer lasting performance. To be stronger, smoother and simpler. Now back to the bike.
