It's a park Tool It just works. The fit was a little loser than I was expecting. I used a 22mm socket rather than an adjustable wrench, worked perfectly.

Works great. Only used it once, and hopefully not again for years.

This tool does not accept a ratchet end so there is no way to properly torque the cassette with a torque wrench. You cannot properly torque with an adjustable wrench. Proper torqueing of the cassette is key to good shifting. Disappointing, Park Tool should know better!
