Bottom Bracket DUB PF-MTB

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