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.


  • One oversized spindle to work across every bottom bracket standard
  • Gutter Seal Technology™ drastically improves sealing against the elements
  • Significantly lighter than GXP® system
  • Sealed cartridge bearings
  • ISO 4210 compliant.
