Bottom Bracket - English (BSA), 68/73mm, For 24mm Spindle

Wolf Tooth English (BSA) Bottom Bracket is precision-engineered for riders who demand durability, reliability, and ultra-smooth performance from their drivetrain. Designed and machined in Minnesota, USA, this bottom bracket is built with best-in-class sealing and innovative details that eliminate creaks and boost longevity - no matter the conditions.

PREMIUM SEALING, INSIDE AND OUT
O-ring seals on the spindle and inner shell, a wiper seal between bearing and end cap, and a labyrinth-style end cap design all work together to keep water and trail debris out, so your ride stays quiet and your crankset spins smoothly.

NO CREAKING, JUST POWER
Custom polymer spindle bushings prevent metal-on-metal contact between the bearing and crank spindle, eliminating creaking and extending the life of your crankset.

CUSTOM BEARINGS FOR MAX PERFORMANCE
Built from hardened AlSl 52100 chrome steel and treated with a ZNA corrosion-resistant coating, the bearings are specifically designed for reduced friction and long-term durability. Ball size, width, and count are all fine-tuned for each spindle diameter.

FITS 68MM OR 73MM SHELLS With an adjustable-width shell design, this English-threaded BSA bottom bracket is compatible with both 68mm and 73mm frames.
