Sram

We've engineered the SRAM DUB crank spindle to be a true unifying component: one oversized spindle to work across every bottom bracket standard.

The new SRAM DUB bottom bracket series has a simple job connect your crankarms and protect the smooth, long-lasting application of power to your drivetrain.

Use only SRAM parts with SRAM components. Installation of parts and accessories not originally intended could result in less than optimal performance and/or injury. For in-depth service information on SRAM products, refer to our website at www.sram.
