Grunge Transmission Brush

Designed to clean every part of a bicycle's drivetrain, the Finish Line® Grunge Brush™ features two unique brushes. The horseshoe-shaped bristles on one end are perfect for cleaning greasy chains, sprockets, and dirty chainrings. The long, straight bristles on the other end are designed to clean cassettes and derailleurs. The Grunge Brush™ can be used with water, or for a deeper clean, combined with one of our powerful Finish Line® liquid degreasers.
