BB DUB Pressfit Road 86.5 Bottom bracket

SRAM DUBâ„¢ is the single replacement for 30mm and 24mm bottom bracket spindles options. They fit all frame shell standards and DUBâ„¢ does NOT introduce any new frame shell standards. DUBâ„¢ The relationship between bottom bracket spindle and bearing is the core of DUBâ„¢ technology.

It’s where stiffness meets 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.
