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

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.

Nice tool!

Perfect tool to install my Sram cassette. Park Tool makes quality products

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

Works great for centerlock rotors and cassettes on 12mm through axle wheels.

Whats there to say about Park Tools that hasnt already been said? Well made, good price, and did its job!

NICE PRODUCT

If you need this tool, its exactly what you want.

They just work and are solid construction.

This tool works perfectly and is just what you would expect from Park.
