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

Its PARK TOOL...nuff said

Tool worked great for my my new bike rotor installation

This tool is needed for my cassette removal and installation

Works like a charm for the newer Shimano centerlock disc brakes and rear axle with thru-axle applications.

Easy to use. The delivery was quick.

Takes cassettes off and puts them on. Buy it

Quality tool works well

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

This is a solid tool. Well priced and well built. The good quality of Park Tools it’s noticeable in this part.

Works
