The SRAM DUB bottom bracket series has a simple job: connect the cranks and protect the smooth and long-lasting application of power to the drivetrain. To enable this singular focus, we designed the DUB chuck to be the only true unifying component. An oversized spindle to work on all bottom bracket specifications. For better compatibility with the crank. For better protection from the elements. For longer lasting performance. To be stronger, smoother, simpler. Now, back to the running.
