Intuitive and easy to use, the new Grip Whip cassette removal tool makes any cog removal project fast. Designed for one-handed, ambidextrous operation, with an ergonomic, textured rubber grip for comfortable handling, this tool is compatible with all 5-13 speed cassettes from SRAM, Shimano, and Campagnolo, including SRAM Transmission. Simply press the thumb lever to open it, then let the tool's spring-loaded clamp closure grip any 10-24T cog with 6 secure, non-slip contact points. And if higher-than-usual lockring nut tightening torque is required, extend the handle and increase leverage using an 8mm L-wrench in the handle's 8mm socket.
