Wolf Tooth | Center Lock Disc Rotor Lock Ring

Tiny detail. Big peace of mind.

The Wolf Tooth Center Lock Disc Rotor Lock Ring secures centerlock rotors firmly to modern hubs for reliable, rattle-free braking.

Designed as a premium alternative to stock lock rings, this CNC-machined piece prioritizes precise fit, clean installation, and long-term durability. Compared to generic steel options, Wolf Tooth’s 7075‑T6 aluminum construction saves weight, adds color-matched finish options, and maintains consistent torque retention—while offering both external-spline and thinner internal-spline options to suit different frame and fork clearances.
