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

Is the best, worked perfectly! Used on Sram cassettes.

Works great

This tool did its job in installing a cassette on a bike wheel. The 12mm pin keeps it stable.

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.

Works good no issues

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.

Quality seems good it worked perfect for my sram xd cassette

Nice quality part. Can’t go wrong with this. Definitely recommend.

This tool rocks! I had a really tight cassette lockring. I put this lockring tool in the bench vise and cranked it down tight, set the wheel on top, then used a chain whip with a breaker bar to finally break it loose. I think a lesser lockring tool would have stripped/failed so Im glad I spent a few extra dollars on quality.
