BSA, also called English thread, is the most common threaded bottom bracket standard. Road and gravel frames use a 68 mm shell and most MTBs a 73 mm shell, both with 1.37" x 24 TPI threads (drive side left-hand). Threaded cups are easy to fit, quiet and simple to service.

Choose by crank spindle: 24 mm for Shimano Hollowtech II, SRAM DUB (28.99 mm), or 30 mm cranks. Use the filters to narrow by spindle, bearing type and brand.
