The new SRAM DUB bottom bracket series has a simple job: it connects your cranks and ensures the smooth, sustained application of power to your drivetrain. To enable that singular focus, we designed the DUB spindle to be the one true unifying component. An oversized spindle to work across all bottom bracket standards. For better crankset compatibility. For better protection from the elements. For longer-lasting performance. For stronger, smoother, simpler. Now, back to the race.
