SRAM DUB Technology & Ceramic Bearing Performance
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 integration between chainring, crank, spindle, and bottom bracket. It's this holistic approach to developing a complete system that delivers better drivetrain performance.
SRAM engineered the DUB system to be a truly unifying component: one oversized spindle to work across every bottom bracket specification. The SRAM DUB Ceramic BB is the ticket for getting the lightest and most durable crank system onto your bike. Better crankarm compatibility, better protection from the elements, and better overall performance.
