## Description

Review: Does the job! - Fits my bike perfectly, great tool!
Review: Well built and works perfectly - This worked perfect for removing the rear cassette from my bike. I did not get the tool that wraps around the cassette but I was still able to remove the cassette using a technique I found on the web (e.g. "what to do if you our out in the field and need to replace it".). Park tool seems to make some of the best tools for bikes and is a good value based on the quality of the product.

### ⭐⭐⭐⭐⭐ Good tool to have in your kit.
*by R***Y on September 20, 2025*

The usual excellent Park Tool quality. This is one to have in your tool kit, as it works with 80% of the freehubs you're likely to encounter. You pay a little more for Park tools, but if "Made in the USA" means anything to you, and you want your tools to last, it's worth the extra cost. Well packaged
