The SRAM DUB bottom bracket series has a simple mission: to connect the cranks and ensure smooth, lasting power transfer to the drivetrain. To enable that singular focus, we designed the DUB spindle to be the one true unifying component. An oversized spindle designed to work with all bottom bracket standards. For better crank compatibility. For better protection from the elements. For longer-lasting performance. To be stronger, smoother, simpler. Now, let's get back to riding.
