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

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

Worked exactly as expected.

Works exactly as designed

I bought this cassette lock ring tool since my older tool didnt have clearance for the axle on the newer thru-axle hubs. The FR-5.2GT has plenty of clearance and fully engaged the cassette lock ring. The center pin didnt seem necessary to line up the tool, but didnt cause any problems either.

I had to remove my rear cassette to upgrade my hub on my Shimano 11-34 GRX, and no other tool would fit. Soviet-era tough, just like every other Park Tool item. Fits perfectly in the largest of their sockets, and with the torque wrench, it now has the correct tightness of fit down to the Nm rating on the gears. If you like tinkering with your bike, and saving money on maintenance, this is a great addition to your kit. Happy riding.

Tool is exactly what it is intended for. Works perfectly.
