Singular Focus. Better Solution.
SRAM has engineered the SRAM DUB crank spindle to be a true unifying component: one oversized spindle to work across every bottom bracket standard. If you only drink cappuccinos before 11, sing Verdi on long climbs, and named your cat Fellini, the SRAM DUB Italian BB is the ticket for getting SRAM's lightest and most durable crank system onto your bike. Better crank arm compatibility, better protection from the elements. With style.
Technology
DUB
The relationship between bottom bracket spindle and bearing is the core of DUB technology. It’s where stiffness meets durability. SRAM took it a step beyond conventional thinking and made everything simpler better integrating the relationship between chainring, crank, spindle and bottom bracket. It’s this approach to developing a complete system that equals better drivetrain performance.
