WOLF TOOTH BSA Bottom Bracket Wolf Tooth BSA Bottom Brackets are engineered to be smooth, durable, lightweight, fast, and serviceable at home. Our ground-up design features custom bearings, seals, bushings, and cups, which eliminate creaking and balance best-in-class weather sealing with optimized bearing radial compression, alignment, and preload for low drag. Wolf Tooth bottom brackets are machined at Wolf Tooth HQ in Minnesota, USA. Best-In-Class Sealing, No Sacrifice In Speed Thoughtfully engineered sealing is designed to balance low drag with superior performance in all conditions. The grouping of a spindle o-ring, seals on the bearing/bushing gutter, light inner and outer bearing race seals, shell o-rings, and a labyrinth-style end cap ensure your bottom bracket will spin smoothly no matter what conditions you ride in. No Creaks Custom bushings separate the bearing inner race and crank spindle to eliminate metal-on-metal contact, the leading cause of bottom bracket creaks. This bushing also helps enhance bearing longevity with an interface to the bearing gutter seal for maximum weatherproofing. No metal-on-metal contact, no creaks. It's simple.
