Sram Dub BB30 42mm x 68/73mm



The relationship between bottom bracket spindle and bearing is the core of SRAM DUB BB technology. It's where stiffness meets durability. SRAM took it a step beyond conventional thinking and made everything simpler and better integrating the relationship between chainring, crank, spindle and bottom bracket. It's this clear system approach that equals better drivetrain performance. DUB bottom brackets fit all frame shell standards, and does NOT introduce any new frame shell standards.
