The SRAM Innenlager DUB BSA Wide is a high-quality bottom bracket designed to provide a smooth, durable interface between your SRAM DUB crankset and a BSA threaded frame. Built around SRAM’s proven DUB standard, it uses a 28.99 mm spindle diameter to optimize stiffness, durability, and compatibility while keeping the system simple. The BSA Wide version is tailored for modern frames that require a wider chainline, such as many gravel, MTB, and some road or adventure bikes, ensuring proper drivetrain alignment and reliable shifting performance.
With sealed cartridge bearings and robust external cups, the SRAM Innenlager DUB BSA Wide is engineered to keep out dirt, water, and grit, extending service life even in harsh riding conditions. Installation is straightforward with standard external bottom bracket tools, making it a practical upgrade or replacement for home mechanics and professional workshops alike. Whether you are building a new bike or refreshing a worn drivetrain, this bottom bracket delivers efficient power transfer, quiet operation, and long-lasting performance that complements any SRAM DUB crankset.
