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. Now, back to the ride.
