DUB BSA 83mm Bottom Bracket ensures lasting durability for DUB cranksets
What Our Gearhead® Experts Are Saying:
"This 83mm DUB BSA is my go-to for threaded downhill frames. Install it once with the right torque, and it stays silent all season—smooth spin and great bearing life, even after messy park laps."
The SRAM DUB BSA 83mm Bottom Bracket brings unified performance to threaded downhill and gravity bike frames. Its 83mm shell width matches the wider stance of modern DH cranksets, providing increased stability and clearance for aggressive trail riding. At the core, SRAM’s 28.99mm DUB spindle balances stiffness and efficiency, transferring power directly into forward motion while maintaining lightweight construction.
Gutter Seal Technology protects precision bearings from trail contaminants, ensuring quiet, low-drag performance season after season. Compatible with DUB crankarms across the Eagle and Descendant lines, this bottom bracket simplifies drivetrain integration while boosting durability and alignment accuracy. For riders who demand flawless engagement and long-term reliability, the DUB BSA 83mm delivers uncompromising performance for hard-charging terrain.
