The CP-1.2 is a great alternative to a traditional chain whip for removal and installation of bicycle cassettes. Utilizing a simple-yet-effective design that allows for one-handed operation the CP-1.2 quickly grips cogs with 9 to 24 teeth to securely hold the cassette in place. The long jaws and handle provide ample leverage for the most stubborn lockrings. Forged steel construction with a spring loaded return and comfortable dual density grips for a lifetime of use.
