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, providing better compatibility with the pedal board, improved protection against the elements, and more durable performance. It is stronger, more flexible, and simpler, allowing you to get back to racing.
