The SRAM DUB bottom bracket series is designed to connect crankarms and protect the drivetrain’s smooth and long-lasting power application. It features an oversized spindle that works across every bottom bracket standard, simplifying crankarm compatibility. The bottom bracket also includes sealed cartridge bearings and Gutter Seal Technology that enhances sealing against the elements. Additionally, it is significantly lighter than the GXP system and is compatible with English BSA thread with 68/73mm shell widths.
