BB-set SRAM DUB BB30 42 x 68/73mm

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. To allow that singular focus, we've engineered the DUB spindle to be the one true unifying component. One oversized spindle to work across every bottom bracket standard. For better crankarm compatibility. For better protection from the elements. For longer-lasting performance. To be stronger, smoother, simpler.

It’s where stiffness meets durability. We took it a step beyond conventional thinking and made everything simpler—better integrating the relationship between chainring, crank, spindle and bottom bracket. It’s this approach to developing a complete system that equals better drivetrain performance.
