Park Tool Sprocket Remover/Chain Whip (3/32)
Park's Sprocket Remover/Chain Whip is a shop-quality chainwhip providing excellent leverage and a grip that won’t slip. It features a heavy-duty, heat-treated head, a tough chain held on with hardened bolts and a comfortable, round, vinyl-coated handle that's easy on the hands. This fine tool is compatible with all cassettes and freewheels.
The Sprocket Remover is a chainwhip. Place it on the cassette as shown and hold the handle to keep the cassette from turning while you remove the cassette lockring with a remover and adjustable wrench (remover and adjustable sold separately). The SR-2 can also be used with another chainwhip to separate freewheel cogs.
