This is a lockring from TRP designed for center lock disc brakes. It features internal teeth, making it a great fit for hubs with 12 mm thru - axle or quick release mechanisms. The lockring is made of aluminium and is highly compatible with 9 mm quick release, 10 mm quick release, and 12 mm thru - axles. It's also suitable for all TRP center - lock brake rotors, ensuring a wide range of applications.

Using this TRP lockring is easy. First, make sure your brake rotor is properly aligned with the hub. Then, place the lockring over the rotor and turn it clockwise until it's securely tightened. When installing, be careful not to overtighten as it may damage the lockring or the rotor. As for maintenance, regularly check the tightness of the lockring. If you notice any looseness, tighten it gently. Keep it clean by wiping it with a dry cloth after each use. Avoid using harsh chemicals as they might corrode the aluminium material.
