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

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 tool as always from Park Tools. You can always trust the quality of Park Tools from my experience.

How did I ever get by without one of these?

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.

I did what is was supposed to do.

worked perfectly for my through axle bike.

Works. Feels solid. Guide pin is nice. Works for cassette removal and direct mount Shimano rotor removal install.

Nice product

Quality seems good it worked perfect for my sram xd cassette

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