PARK TOOL Kettenreinigungsgerät CM-5.3

Now also compatible with mid-motor and backpedal. Works with all gear chains (5, 6, 7, 8, 9, 10, 11 and 12 speed) as well as some input models and e-bikes. A strong magnet on the bottom of the liquid container binds metallic particles that are washed by the chain. A special sponge sucks the cleaner off the chain while it comes out, minimising drips and dirt. The robust handle makes the CM-5.3 easy to use and control.
