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

worked as expected, great tool. I will get many years of use from it.

Simple. This works great as it keeps the tool square with the hub and keeps full engagement of the teeth.

Worked as intended

Works great, no need to try to keep in in place w the axle when loosening.

Nice Item!!!

I have to admit I was skeptical. I had a X01 cassette that didnt want to come off my Hope cassette carrier. I bought this and put it in the vice and spun the cassette and it came off easily. Maybe it was the through axle pin, maybe it was the right depth. Either way, it works for what I needed. Park Tools comes through again.

Great too where others were popping out w/o the pin on disc hubs

Works exactly as designed

They just work and are solid construction.

Lock ring got chewed up
