Finish Line Grunge Brush

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