Specifications

Experience unparalleled durability and smooth performance with the Wolf Tooth Bottom Bracket - English (BSA), designed for 24mm spindle cranksets in 68/73mm shells. Crafted in Minnesota, USA, this high-performance bottom bracket is engineered for mountain biking, gravel riding, and XC racing, delivering reliable power transfer and seamless pedaling.

Materials & Construction

Built with precision machined aluminum (AlSi 52100 chrome bearing steel hardened to Rc 61-66), the Wolf Tooth BSA bottom bracket combines lightweight strength with outstanding wear resistance. The innovative ZNA corrosion-resistant coating ensures optimal longevity, even in harsh weather conditions.

Performance & Engineering Excellence

Featuring best-in-class weather sealing, this bottom bracket incorporates o-ring seals on the spindle and inner shell, a labyrinth end cap design, and a high-quality wiper connection seal. These features protect internal bearings from water, mud, and trail debris, minimizing maintenance and preventing creaking. The separate spindle bushings prevent metal-on-metal contact, reducing noise and extending component lifespan.

Advanced Components & Technology

The custom chrome bearings with hardened race steel deliver reduced friction, ensuring a remarkably smooth pedaling experience. The adjustable-width shells accommodate 68mm and 73mm frame shells, providing versatile fitting for various bike geometries. Compatible with Shimano Hollowtech II and RaceFace EXI spindle interfaces, this bottom bracket offers excellent versatility and reliable performance.

Style & Use Case

Designed with vibrant orange aesthetics, the Wolf Tooth Bottom Bracket not only enhances your bike's visual appeal but also guarantees top-tier functionality for mountain bikers, cross-country racers, and adventure riders seeking a durable, lightweight, and maintenance-friendly solution.
