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