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

What the Dr ordered to remove/replace my mtb cassette

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

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

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

Worked as intended

Very sturdy, but the guide pin did not fit my cassette (my fault). I contacted Park Tool and was informed that you can just hammer out the guide pin (which I did) and it worked great.

Easy to use. The delivery was quick.

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.

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.

Fits really good into the axel.
