SRAM DUB Compatible with PressFit, English, BB30, BB386, Ceramic Bicycle Bottom Brackets

Engineered for broad compatibility and long-term performance, this DUB bottom bracket system unifies a better engineered bottom bracket with an oversized spindle to work across multiple shell standards. It delivers a more uniform fitment approach, improved durability, and reliable crank compatibility for a wide range of road, mountain, and specialty frames.

Advanced sealing and bearing technology reduce maintenance and protect performance. Gutter Seal Technology dramatically improves resistance to contamination, while sealed cartridge bearings provide smooth operation and consistent feel. A ceramic bearing option is available for reduced friction and enhanced longevity when maximum efficiency is desired.

Designed for flexible installation, the system supports press-fit and threaded shells as well as common interfaces such as BB386, BB30/BB30A, English/BSA, Italian, and Cannondale Ai arrangements, plus E-Type and SuperBoost configurations used on modern mountain and fatbike platforms. Specific left-cup options accommodate frames with integrated crank interfaces.

Lightweight compared with legacy designs and purpose-built for everyday riding and racing, this bottom bracket offers a straightforward upgrade path: improved sealing, durable construction, and broad crank compatibility for a cleaner, more efficient drivetrain.
