DUB Italian Bottom Bracket

We've engineered the SRAM DUB crank spindle to be a true unifying component: one oversized spindle to work across every bottom bracket specification. 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 our lightest and most durable crank system onto your bike. Better crankarm compatibility, better protection from the elements. With style.

FEATURES:

• One oversized spindle to work across every bottom bracket specification
• Gutter Seal Technology™ seals against the elements
• Significantly lighter than GXP® system
• Sealed cartridge bearings available in both stainless and ceramic versions

Technology:

DUB

The relationship between bottom bracket spindle and bearing is the core of DUB technology. It's where the stiffnesss meets durability. We took it a step beyond durability. We 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.
