The new SRAM DUB series of bottom brackets has a simple function: it connects your cranks and ensures smooth and lasting power transfer to your drivetrain. To enable this unique concentration, we designed the DUB axle to be the only truly connecting component. A single oversized spindle that works with all bottom bracket standards. For better compatibility with the pedal board. For improved protection against the elements. For more durable performance. To be stronger, more flexible, and simpler. Now back to racing.
