Intuitive and easy to use, the Grip Whip cassette removal tool makes quick work of any cog removal project. Designed for ambidextrous one-handed operation with an ergonomic, textured rubber handle for comfortable grip, this tool is compatible with all 5-13 speed cogsets from SRAM, Shimano and Campagnolo, including SRAM Transmission. Simply depress the thumb lever to open, then let the tool's spring-assist jaw closure latch onto any cog from 10-24T with 6 points of secure, slip-free contact. And if more lockring torque than usual is required, extend the handle and add leverage by using an 8mm L-handle hex wrench in the handle's 8mm receiver.
