The SRAM Innenlager DUB BSA bottom bracket is designed to provide a smooth, durable interface between your SRAM DUB crankset and a BSA threaded frame. Built around SRAM’s DUB standard, it uses a 28.99 mm spindle diameter that simplifies compatibility while optimizing stiffness and long-term reliability. The BSA (British Standard) threaded design is widely used on both mountain and road bikes, making this bottom bracket a versatile choice for many modern frames.
Engineered with high-quality sealed bearings, the SRAM Innenlager DUB BSA helps keep out dirt, water, and grit, ensuring consistent performance in all weather conditions. The robust construction minimizes friction and improves power transfer, so more of your effort goes directly into forward motion. Whether you are upgrading an existing bike or completing a new build, this bottom bracket offers an easy-to-install, low-maintenance solution that pairs perfectly with SRAM DUB cranksets. It is ideal for riders who value reliability, efficiency, and a clean, creak-free drivetrain.
