Don't waste your time on cheap lock-rings! Quality lock-rings are essential to keep your brake rotor secure when experiencing constant heat cycles.
For Rotors over 180mm, we recommend steel lock-rings.
If you're using Chris King Road hubs, the SM-RT900 is the best option to use for low clearance on the adjuster.
