What Our Gearhead(R) Experts Are Saying:"I clamp this onto the chain, back pedal for thirty seconds, and the grime that usually takes me twenty minutes with a rag is gone. The rotating brushes actually get into the side plates, not just the outer links."A grimy drivetrain shouldn't eat up a Saturday afternoon, and the Chain Cleaner Tool Kit makes sure it doesn't. Clamp it onto the chain, back pedal for thirty seconds, and the rotating brush design works dirt out of every link and side plate without ever pulling the chain off the bike, leaving more time for the ride and less for the cleanup.
