SRAM DUB English Bottom Bracket - English/BSA, 68/73mm, MTB Boost 55mm CL, Black

The SRAM DUB English Bottom Bracket is a threaded bottom bracket for 68 or 73mm English (BSA) shells on mountain bikes using a Boost 55mm chainline. It accepts SRAM DUB cranks and uses larger bearings and improved sealing for longer life in wet and muddy conditions. Threaded cups install easily with a standard bottom bracket tool and resist creaking better than many press-fit designs. It is one of the most common mountain bike bottom brackets and a direct replacement for worn DUB units. It suits most trail bikes.
