Forget the constant slipping of homemade chain whips with the solid and sturdy performance of the Park Tool Shop Sprocket Remover/Chain Whip - SR-2. 2. This sprocket remover/chain whip works with 5 through 12-speed mountain and road cassettes, meaning it's compatible with both Shimano/SRAM and Campagnolo. The heat-treated steel head with hardened bolts firmly hold the chain in place, while the rounded, vinyl-coated steel handle offers ample leverage and grip.
