ShimanoM8010 Centerlock Lockring for 12/15/20mm Axles(Return to Product Page)

Needed these for a wheel build. So much easier than 6 bolt. Yes- you do need a special tool but it�s so easy and fast to use.

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 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!

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.

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.

Needed this to install the front wheel disc rotor on an ENVE 4.5 AR wheel. Excellent shimano quality.

Works seamlessly with Campagnolo 140 & 160 CenterLock rotors.

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.

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