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.

This tool is needed for my cassette removal and installation

easy to use. well designed. Not sure you need the blue guide rail, but it definitely is a snug and strong fit to take off the rear cassette.

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

Works

They just work and are solid construction.

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.

I wish it had proper integration with park torque wrench, I need extra socket to drive cassette tool. Otherwise perfect. Good steel, easy fit.

Great tool
