Wolf Tooth Centerlock Rotor Lockring – Internal Spline

Wolf Tooth Centerlock Rotor Lockring – Internal Spline is a precision-machined solution for securing a centerlock rotor to your hub when clearance is tight. Designed with a slim internal spline interface, this lockring fits frames and forks that do not provide enough space for external spline tools, making it an ideal option for modern disc brake setups with limited tolerances. Machined from high-strength 7075-T6 aluminum and paired with a stainless steel shim washer, this lightweight lockring offers secure rotor retention without unnecessary bulk. At just 8.5 grams, it keeps rotational weight low while maintaining the strength required for reliable braking performance.
