Chain Cleaner Set. Universal chain cleaner set consisting of: CM-5.3 chain cleaning device, GSC-1 sprocket cleaning brush, and citrus degreaser for chain cleaning, 240 ml. Insert the chain, rotate, and you're done. The CG-2.4 Chain Gang chain cleaning set includes the CM-5.3 chain cleaner, the GSC-1 sprocket cleaning brush, and 240 ml of citrus degreaser cleaning fluid. With the CM-5.3, chain cleaning becomes even easier. The cleaning device provides a multi-stage, active cleaning process. The chain is first thoroughly scrubbed with degreaser using rotating brushes and then rinsed with diluted cleaning fluid. A strong magnet (Grade 5) attracts washed-off metal particles and prevents them from re-depositing on the chain. At the exit, the chain is wiped on a durable sponge. With the double-sided handle, the CM-5.3 can be used on all bikes, including e-bikes with mid and hub motors. The handle also provides stability. Brushes and sponges are available as replacement parts.
