SRAM DUB PressFit Ceramic Bicycle Bottom Brackets

A versatile bottom bracket engineered around DUB™ technology, available with high-performance ceramic or sealed cartridge bearings. One oversized spindle design provides a uniform approach to fitment across a wide range of press-fit and threaded bottom bracket shells, delivering improved sealing, reduced friction and long-term durability for SRAM DUB cranksets.

Key features include Gutter Seal Technology for enhanced protection against contamination, sealed cartridge bearings for smooth rotation, and a lighter overall package compared with earlier systems. Built for road, MTB and fatbike applications, the design also accommodates frame-specific left cups for popular frame standards from major manufacturers, and supports chainline and boost configurations commonly used on modern bikes.

Whether you choose the ceramic option for lower friction and increased bearing life or the robust sealed bearing version for reliable all-condition performance, this DUB bottom bracket delivers quiet, efficient pedaling and solid durability. Compatible with all SRAM DUB cranks and offered in variants to suit different shell types and installation methods, it’s a practical upgrade for riders seeking consistent performance and improved protection on every ride.
