What is the difference between the pin and no pin? I'm trying to attach a cassette to a road wheel.

Park describes the pin as helping to stabilize the tool


  • Familiarity: I've put it through the wringer

Just what I needed. My old cassette tool would not fit this bike. I found this Park tool better and cheaper here than the shop I go to.

Works as advertised

  • Familiarity: I've used it once or twice and have initial impressions

Works as I expected. A nice item to have.


  • Familiarity: I've used it several times

It was necessary to buy this to swap out my casseette and upgrade to the Eagle GX drivetrain. Worked great, can't go wrong.

Gotta Have one

Do yourself a favor and pick one up. Not worth having to go to a shop to pull your cassette. Quality tool from Park tool.

Great addition to the bike drawer

Really helpful when trying to remove your cassette to give it a good cleaning. Everyone should have this in their tool arsenal.
