SRAM DUB Bottom Bracket

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.
