Sram DUB bottom bracket English/BSA

Forward-thinking yet fully backward compatible, the SRAM DUB bottom bracket/crank technology is a workhorse that never gives up. Designed for the most demanding professional riders and for anyone who wants to worry about nothing after installation. DUB is compatible with all common bottom bracket standards.

The system features better sealing than ever before while fitting into any frame. At the same time, it paves the way for a novel crank axle, resulting in the lightest crankset in the world to date. DUB sets a new standard in durability that everyone can benefit from.
