CeramicSpeed BSA MTB Bottom Bracket - BSA Thread 73mm 24mm Spindle Coated Races BLK

Engineered to slash friction and maximize power transfer, the CeramicSpeed BSA MTB Bottom Bracket keeps your pedal stroke smooth on rugged MTB trails. With longer service life than traditional steel bearings, it maintains consistent performance through muddy climbs and high-output days, so you ride farther with less maintenance. It’s compatible with English-threaded frames and 24mm spindle systems for Shimano Hollowtech II setups, making it a reliable upgrade for serious mountain bikers.

Who is this for?

Ideal for riders who demand efficient power transfer, reduced drivetrain resistance, and long-lasting performance on aggressive mountain biking routes. If you ride on steep ascents, technical descents, or all-day epics and want a ready-to-install upgrade for English-threaded 73mm shells with a 24mm spindle, this bottom bracket fits your Shimano Hollowtech II-equipped bike.
