The new SRAM DUBâ„¢ bottom bracket series has a simple jobâ€”connect your crankarms & protect the smooth, long-lasting application of power to your drivetrain. To allow that singular focus, weâ€™ve engineered the DUBâ„¢ 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.
