SRAM DUB Race/MTB Pressfit BB30 bottom bracket-Black

The SRAM DUB™ (Durable Unified Bottom Bracket) 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 standard. For better crankarm compatibility. For better protection from the elements. For longer-lasting performance. To be stronger, smoother, simpler.
