SRAM bottom bracket DUB BB30

The SRAM DUB bottom bracket series has a simple job— connect your crank arms 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 specification. For better crank arm compatibility. For better protection from the elements. For longer-lasting performance. To be stronger, smoother, simpler.
