Pedro's Vise Whip
Face it. Chain whips are a pain to use--that's why Pedros created the Vise Whip. Now you can remove cassettes quickly and easily without the juggling act. Clamp the Pedros Vice Whip on cogs from 11 to 23 teeth to hold it in place, then just use a cassette socket to unscrew the keeper. Wasn't that easy?
