Whip it real good

  • Familiarity: I've used it several times

Solid must have tool for any riders toolbox. Simple to use when removing cassettes (pair with lock ring tool found here on our site: )

I like the nice big sturdy handle and the wrench on the flip side of the tool is perfect for twisting a lockring tool. Makes removing cassettes of all kinds nice and simple to keep you riding.


  • Familiarity: I've used it several times

So after my old chain whip broke I picked up this one and have used it a handful of times. It has a great handle and is super easy to use.

But now I find I never use it b/c I picked up the Pedro's Vise Whip and that is my favorite option when needing a whip.

Can this actually be used with 11 speed? on park tools' site it says up to 10 speed, but I can't imagine what's the difference of 10 and 11 speed that would prevent this tool being used.

Hello Chi, I've personally used this plenty of times on my 11 speed bikes. It works just fine. Send any questions to and I can answer them directly. Thanks!
