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

Takes cassettes off and puts them on. Buy it

Nice quality part. Can’t go wrong with this. Definitely recommend.

Nice Item!!!

worked as expected, great tool. I will get many years of use from it.

The way my through axle wheel interfaces with the cassette my old cassette removal tool with only go in about 1 mm and was hard to tighten enough. This thing with the guide pin made a huge difference.

Just that I want, Thanks!!!

Quality seems good it worked perfect for my sram xd cassette

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.

These are great tools. If you want the Best Buy his for thru axles

Nice lock ring tool for 12mm thru axles. Highly recommended for those with disc brakes. Holds tight and steady.
