SRAM DUB Italian Bottom Bracket – 70mm

The SRAM DUB Italian bottom bracket brings the simplicity and durability of the DUB system to road frames using a 70 mm Italian-threaded shell. Featuring SRAM’s oversized 28.99 mm DUB spindle interface, this bottom bracket delivers improved stiffness, compatibility, and long-lasting performance. Gutter Seal Technology enhances protection against water and debris, while the sealed steel cartridge bearings ensure smooth, reliable rotation in all riding conditions.

Designed to work seamlessly with any SRAM DUB road crankset, this BB is significantly lighter than previous GXP systems while offering broader frame compatibility and improved durability.
