Designed to clean every part of a bicycle drivetrain, the Finish Line® Grunge Brush™ features two unique brushes. Horseshoe shaped bristles on one end are perfect for cleaning greasy chains, crusty jockey wheels, and grimy chain rings. Long, straight bristles on the other end are designed for cleaning cassettes, and derailleurs. The Grunge Brush™ can be used with water, or for a deeper clean, combined with one of our powerful liquid Finish Line® Degreasers.
