The SRAM DUB bottom bracket series has a simple task: connect the cranks 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. 

FEATURES

• An oversized spindle designed to work with all bottom bracket specifications.

• Significantly lighter than the PFGXP system
