Editorial Review
Here's a surprise: Bicycle chains get dirty. And dirty chains are self-destructive, not only burning themselves out prematurely, but also abusing the rings and cassette, shortening their lives as well. To stop the cycle, clip the Cyclone over the chain, fill it with the solvent of your choice and backpedal: Brushes inside detox the chain, leaving it brighter than crazy Tom Cruise's smile.
