Park Tool FR-5.2GT Cassette Lockring with Tool 12mm Pin

Does as its supposed to and the color is very nice.

Worked exactly as expected.

Works

I used this to install an 11-speed cassette on a boost size hub with a Shimano HG driver. The hub uses a thru-axle. Nice tool.

Who can torque to 40Nm with a 1 box wrench? And who can be bothered to use a chain whip when an impact driver will take a cassette lockring off in half a second without even needing to hold the cassette? This tool would be great if it directly supported 1/2 drive, but requiring a 1 socket to adapt this to anything makes it way less useful.

Nice lock ring tool for 12mm thru axles. Highly recommended for those with disc brakes. Holds tight and steady.

it works, but for the price I think they couldve figured out by now to make it more handy... like idk, not needing an onch socket or an awkward big ass crescent wrench. would be really nice if this could just be direct onto a socket wrench.

These are great tools. If you want the Best Buy his for thru axles

Works great for centerlock rotors and cassettes on 12mm through axle wheels.

So this is the 4th version of this tool that I have purchased and like all of the others, it is an improvement over my prior ones. Well, to be clear, it works well for wheels with thru-axle hubs only - I will definitely keep my other tools for my bikes with conventional axles and skewers. It also works well for removing centerlock disc rotor lockrings. Considering what I paid for my new bike with all the new tech, I figure an additional $14 for this modified tool is a reasonable investment.
