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

Did the job

Worked as intended

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

Fits really good into the axel.

Its PARK TOOL...nuff said

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

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

Worked like it should.

for removing a cassette on a through axle. The stabilization pin does its job

I bought this specifically to work with the 12mm thru axle on my Surly ECR that came installed with the NX Eagle cog set. Its the best way for me to use a torque wrench and snug the cassette to 40NM. Works perfectly!
