Several weeks ago, Pedro’s USA sent us a couple of tools to review. The first is their “Vise Whip“, an ingenious tool that eliminates the hassle and potential breakage of using a traditional chainwhip.

Here’s a little about the tool from the Pedro’s USA website:

–Locking jaws that won’t slip
–Fits cogs from 11T to 23T*
–Compact enough for the toolbox
–Heat-treated steel tough enough for everyday use

Anyone who has used a traditional chainwhip to hold a cassette or freewheel in place while cogs or lockrings are unscrewed knows that such tools can be tough to manage. They’re fiddly and they have a tendency to snap retaining pins just when you’ve got a lot of torque on the tool. The Pedro’s Vise Whip eliminates all of this hassle…it locks solidly onto cassette or singlespeed cogs and will not move if set correctly.

Based on the toolbox staple known as Vise Grips, this Pedro’s tool adjusts with the same style of threaded screw and locking lever. Clamp it onto the cassette and apply lockring remover/wrench to unscrew the lockring. Simple as that!

The Vise Whip works wonderfully for folks who run singlespeed bikes, too. For singlespeed MTB riders who want to change up their gearing for specific conditions or people who run 3/32″ fixed cogs on the street or track, this tool makes such gearing swaps very simple.

The people who run 1/8″ track cogs are out of luck, though…the Vise Whip’s jaws are listed as not big enough to fit over the larger cog width. I haven’t tried this myself, though, as I had no 1/8″ cogs around. Perhaps if the demand is there, Pedro’s will make a version for 1/8″ cogs?

Overall, the tool is sturdy, easy to use and really ingenious…why didn’t anyone think of this before? I’ve used it about a dozen times since I got it in the mail — everything from replacing 8- and 9-speed MTB cassettes to fine-tuning the gearing on my singlespeed MTB/Road “Frankenbike” (tentatively named Craptain America).

This tool has a permanent home in my toolbox — it’s that useful.
