Wolf Tooth Bottom Bracket

It uses custom spindle bushings that act as a buffer between the crank spindle and the bearing inner race. This design prevents the metal-on-metal contact that is the primary cause of creaking in many bottom bracket systems.

This specific model is designed for frames with a BSA threaded bottom bracket shell and is compatible with 30mm spindle cranks. It fits standard 68mm and 73mm shell widths.

It is built for harsh environments. The system uses a multi-stage sealing process, including labyrinth end caps and o-ring seals on the spindle and inner shell, to keep water and grit away from the bearings.

The unit features hardened chrome steel bearings treated with a corrosion-resistant ZNA coating. This combination is chosen specifically to balance smooth rotation with long-term durability in mountain biking applications.

Yes, you will need a bottom bracket tool compatible with the specific external cup pattern used by Wolf Tooth. Because it is a BSA threaded standard, most standard external bearing bottom bracket wrenches will work.
