Wolf Tooth BSA bottom bracket, Shimano 24 mm, orange
The Wolf Tooth BSA bottom bracket for Shimano 24 mm axles is designed for smooth operation, high durability and easy service. It uses its own bearings, seals, bushings and cups, which eliminate unpleasant squeaking and reduce rolling resistance. Specially treated bearings made of hardened chrome bearing steel with ACOSUR ZNA surface coating offer long service life, low noise and corrosion resistance proven by demanding testing. Thanks to sophisticated sealing and precise preload, the bottom bracket delivers top performance in demanding conditions and is suitable for riders who demand reliable and quiet crank operation.
The package includes a complete set of spacers for precise alignment according to frame type and axle diameter, which makes assembly and adjustment easier. The bottom bracket is compatible with standard tools and is designed, machined, and assembled in the USA, with the manufacturer providing a lifetime warranty on the bearings.
