DUB PressFit Bottom Bracket - BB89.5/BB92 89/92mm MTB Boost 55mm CL BLK

The SRAM DUB PressFit Bottom Bracket in black is a game - changer for mountain bikes. It's engineered for SRAM Boost cranksets with a 55mm chainline. Its main job is to connect crankarms and ensure smooth, long - lasting power transfer to the drivetrain. The oversized DUB spindle is a remarkable innovation as it works across all bottom bracket standards, making crankarm compatibility a breeze. Gutter Seal Technology™ significantly enhances protection against the elements, and the sealed cartridge bearings ensure durability. Technical specs include a 41mm bottom bracket shell ID, BB89.5/BB92 frame interfaces, 89.5mm or 92mm BB shell widths, an SRAM DUB spindle interface, and a sleek black color.

Using your SRAM DUB PressFit Bottom Bracket is straightforward. First, make sure your bike frame has the right bottom bracket shell width (either 89.5mm or 92mm) and interface (BB89.5 or BB92). Then, install the bottom bracket into the shell carefully. Attach the SRAM Boost crankset with a 55mm chainline to the spindle. When riding, you'll notice smooth power transfer. As for maintenance, check the seals regularly. If you ride in wet or dirty conditions, clean the bottom bracket after each ride. Use a mild cleaner and a soft cloth. Don't use harsh chemicals as they may damage the bearings. Also, avoid over - tightening the crankarms as it can affect the performance and lifespan of the bottom bracket.
