Product Details
The SRAM DUB BSA Bottom Bracket is designed to seamlessly connect your crankarms while ensuring smooth, efficient power transfer to your drivetrain. Engineered with the DUB spindle, this bottom bracket offers a unified solution across every bottom bracket specification, enhancing compatibility and simplifying your setup. The oversized spindle is a key feature, providing greater strength and smoother operation, making it adaptable to various bike builds.
To protect against the elements, the DUB BSA Bottom Bracket incorporates SRAM’s Gutter Seal Technology, which offers superior sealing to keep out dirt, moisture, and other contaminants, thereby extending the lifespan of your bottom bracket. The DUB system is also significantly lighter than the previous GXP® system, reducing overall bike weight and improving performance. With sealed cartridge bearings available in both stainless steel and ceramic versions, the SRAM DUB BSA Bottom Bracket is designed to deliver long-lasting, reliable performance in all conditions. This bottom bracket is ideal for riders who demand durability, simplicity, and efficiency from their bike components.
