The SRAM DUB™ bottom bracket series has a simple task: to connect the crank arms and protect the consistent, long-lasting application of power to the drivetrain. To enable that unique focus, we designed the DUB™ spindle to be the one true unifying component. An oversized spindle designed to work with all bottom bracket specifications. For better crank compatibility. For better weather protection. For longer-lasting performance. To be stronger, smoother, simpler.
