SRAM DUB 68-73mm English BSA Threaded MTB Bottom Bracket

SRAM DUB™ is a unified solution that replaces both 30mm and 24mm bottom bracket spindles. It fits all frame shell standards without introducing new ones. The core of DUB™ technology lies in the relationship between the bottom bracket spindle and bearing, where stiffness meets durability. SRAM went beyond traditional thinking, simplifying and enhancing the integration of the chainring, crank, spindle, and bottom bracket. This systematic approach results in better drivetrain performance.

Using this SRAM DUB bottom bracket is straightforward. First, make sure your bike frame has the correct 68 - 73mm English BSA threaded shell. Then, carefully install the bottom bracket into the frame shell. When it comes to the crank and chainring installation, follow the normal procedure, and the DUB™ system will ensure a good fit. As for maintenance, regularly check the tightness of the bottom bracket. If you notice any unusual noises or looseness, it's time to tighten it. Also, keep it clean and dry to prevent rust and damage. Avoid using excessive force when installing or removing parts to prevent any potential damage to the bottom bracket.
