The Finish Line Grunge Brush. Chain and gear cleaning has never been faster or easier! Scrub the chain with the compact bristles of The Grunge Brush to clean all four sides of a chain. Use the long bristled end to clean other components like sprockets, derailleurs, crankset, brakes and pedals. Regular component cleaning prevents premature wear and tear on chain and sprockets, eliminates chain skipping caused by dirt and grunge, and assures smooth operation of drive train and brakes.
