The Shimano Bottom Bracket BSA 110mm/68mm is a reliable, threaded bottom bracket designed for smooth, efficient power transfer on a wide range of bikes. Using the classic BSA (English) thread standard and a 68 mm shell width, it is compatible with many road, urban, trekking, and older MTB frames that use this common interface. The 110 mm spindle length is suited to cranksets that require a slightly wider chainline, helping ensure precise drivetrain alignment and consistent shifting performance.
Built with Shimano’s proven bearing technology, this bottom bracket offers durable, low-friction rotation to keep your pedaling smooth in all conditions. Sealed bearings help protect against water, dirt, and road grime, extending service life and reducing maintenance needs. Whether you are refreshing a worn-out drivetrain or completing a custom build, this BSA bottom bracket provides a solid, easy-to-install foundation. Its threaded design makes servicing straightforward for home mechanics and professionals alike, delivering the dependable performance and compatibility riders expect from Shimano components.
