    On lock down.

    Removing a cassette is near impossible without a proper lockring tool, which is why Park Tool hooks it up with the FR-5.2 Cassette Lock Ring Tool. Designed to make your life a little easier, this lockring tool uses a one-inch base perfect for fitting on wrenches or bench vices, and makes it easy to remove cassettes without the removal of cones and locknuts. It has a 12-spline design, and works on Shimano, SRAM, SunRace, Chris King, and other cassette lockrings, along with some Shimano disc brake lockrings.

    • Familiarity: I've put it through the wringer

    I use this to remove the cassette on my road bike, swapping it back and forth to my Wahoo Kickr Core. This is a sturdy tool that I can only imagine will last the rest of my life. This pairs well with the Park Tool Cassette Pliers and a helpful tip when using this lockring is to secure your skewer in place to keep it from jiggling around.

    Perfect tool for the job

      Removing cassettes is super easy with this Park tool. I’ve used this on SRAM force and Apex but it will work with a wide range of cassettes. Takes a few seconds to remove or reinstall with this badboy, a crescent wrench and the Park Tool cassette pliers.

      Great addition to the bike drawer

      Really helpful when trying to remove your cassette to give it a good cleaning. Everyone should have this in their tool arsenal.
