SRAM DUB BSA External Threaded Bottom Bracket

SRAM DUB bottom brackets are where stiffness meets durability. SRAM has made it incredibly simple by integrating the relationship between chainring, crank, spindle and bottom bracket and provide a single replacement for 30mm and 24mm BB spindles options. 

SRAM has created a simple bottom bracket solution that provides better drivetrain performance, increased durability and stiffness without introducing a new frame shell standard to the industry. 

DUB bottom brackets will only work with DUB cranks that use a 28.99mm spindle.
