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

Awesome product from an even better company!

Exactly what I need for cassettes and brake disks on my Shimano group set.

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

Parktool is always a good buy!

Great!

Tool worked great for my my new bike rotor installation

This tool rocks! I had a really tight cassette lockring. I put this lockring tool in the bench vise and cranked it down tight, set the wheel on top, then used a chain whip with a breaker bar to finally break it loose. I think a lesser lockring tool would have stripped/failed so Im glad I spent a few extra dollars on quality.

How did I ever get by without one of these?

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