The Cyclone Chain Scrubber cleans bicycle chain quickly, easily, and effectively - without the hassle and mess of removing the chain from the bike. The Cyclone uses a large solvent reservoir, hundreds of rotating bristles, and a two-step cleaning process to get chains really clean. A strong magnet at the bottom of the Cyclone's fluid resevoir holds metallic particles scrubbed from the chain. To minimize drips and mess, a special wicking sponge draws solvent from the chain as it exits. A sturdy handle makes the Cyclone easy to use and control. Works on most multi-speed and single-speed bikes. Regular use of the Cyclone Chain Scrubber improves shifting performance and extends the life of the chain and other expensive drive train parts.
