Chain and gear cleaning has never been faster or easier. Scrub the chain with the horseshoe-shaped bristles at one end of The Grunge Brush™ to clean all four sides of the chain. Use the long bristles on the other end of the brush to clean components like sprockets, derailleurs, cranksets, brakes, and pedals. Regular component cleaning prevents premature wear and tear on chains and sprockets, eliminates chain skipping caused by dirt and grunge, and assures smooth operation of drivetrain and brakes.
