The Shimano Freehub 12s 148/32 Thru Black is designed for riders who demand smooth, reliable power transfer from their drivetrain to the rear wheel. Built to work with modern 12-speed drivetrains, this freehub body is a key component in ensuring crisp shifting and consistent engagement under load. The 148 mm spacing and thru-axle compatibility make it ideal for Boost-standard mountain bike frames, offering increased wheel stiffness and better handling on rough terrain. Its durable construction and proven Shimano freehub mechanism are engineered to withstand hard riding, frequent climbs, and aggressive descents.
Finished in a sleek black, this freehub integrates seamlessly with a wide range of Shimano-compatible rear hubs and wheel builds using 32 spokes. It is a smart choice whether you are upgrading an existing wheel, replacing a worn freehub body, or building a new Boost wheel from scratch. With Shimano’s reputation for long-lasting performance and easy serviceability, this freehub helps keep your bike running quietly and efficiently, so you can focus on the trail ahead rather than worrying about your drivetrain.
