Overview

Is the Wolf Tooth Internal Spline Lockring Right for Your Frame?

The Wolf Tooth CenterLock Rotor Lockring Internal Spline secures a centerlock rotor onto a centerlock hub. Its slim design with an internal spline lets it fit frames and forks that do not have clearance for Wolf Tooth's External Spline lockring. It is made from 7075-T6 aluminum with a stainless steel shim washer, is made in the USA, weighs 8.5g, and is sold individually.

This version works with 12mm thru axles and QR only. It does not fit Chris King and Project321 rear hubs, and Wolf Tooth says to use its External Spline lockring for those. It installs with the Wolf Tooth Pack Wrench and Cassette Lockring Insert.
