PressFit DUB Bottom Bracket

The 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, SRAM has engineered the DUB™ spindle to be the one true unifying component. One oversized spindle to work across every bottom bracket specification. For better crankarm compatibility. For better protection from the elements. For longer-lasting performance. To be stronger, smoother, and simpler.

• One oversized spindle to work across every bottom bracket specification.
• Significantly lighter than PFGXP system
