Shimano M8010 Centerlock Lockring

CenterLock rotor mounts are our preferred method for attaching rotors to our hubs. It provides even pressure across the disc rotor, so it's less likely to warp due to uneven torque and it's simply faster and easier to install and remove. The XT M8010 Centerlock Rotor Lockring is perfect to keep in the toolbox just in case you might need it on a trip. The lockring is compatible with 12, 15, and 20mm axles and Centerlock rotors and requires an external BB tool to torque the lockring to the hub.


  • Lockring for Centerlock rotors and hubs.
  • Compatible with Centerlock thru-axle hubs and rotors

    Great with King hubs

    Had some Enve wheels with Chris King hubs, and the hub has a large bearing load ring on it that prevents using the standard centerlock ring that comes with a Shimano disc rotor. This solved the problem for cheap.

    Used for SRAM centerlock 160mm Rotors on Easton EA 70 650b rim - great fit and secure

    Used these to secure SRAM 160mm Centerlock rotors on a new set of Easton EA 70 650b rims. This was after calling extremely helpful customer service to inquire. They recommended these lock rings as the only ones that would fit on the Easton hubs. They were spot on, simple to install, have the rotors secure, no issues and excellent support from biketiresdirect customer service!

    Needed for my road bike.

    I bought new wheels for my gravel bike this year. My wheels came with lock rings that use Shimano's cassette tool for installation. These didn't work with my bike's 15mm front axle since the tool didn't fit. I purchased this lock ring as it uses Shimano's bottom bracket tool for installation. This worked great with the bigger wheel axle. Installation was a breeze when paired with a torque wrench and the Shimano BB tool.

    It works of there's enough space.

    This is exactly what you need to lock a disc rotor on your hub. You need to make sure that there's enough room between the lock ring and the fork. Often you need the thinner version for the fork.

    This thing is Thick!

    I wish I had read the previous review about needing space on your fork. Indeed I tried this on two separate road bikes and it does not fit either forks. It feels like this will be a super common problem as one of the bikes was a gravel bike with all kinds of clearance for a 2.1 inch tire, but close to the hub there was not enough clearance for this lockring.

    You know you need one of these if you're installing rotors to your new wheels.

    Does exactly what it should as a well made high quality component.
