Finish Line Grunge Brush Bike Chain & Gear Cleaner – Dual-Sided Bristles for Chains, Cassettes & Hard-to-Reach Areas

Cleans the Entire Drivetrain: Designed to scrub chains, chainrings, cassettes, jockey wheels, and derailleurs for a more thorough clean. Two Brushes in One Tool: Horseshoe-shaped bristles wrap around chains and gears, while long straight bristles reach tight spots like cassettes and derailleurs. Cuts Through Grease & Grime: Stiff nylon bristles easily break up built-up dirt and oily residue for faster, more effective cleaning. Works With or Without Degreaser: Use with water for light cleaning or pair with Finish Line degreasers for deeper drivetrain maintenance. Simple Maintenance, Better Performance: Regular cleaning helps keep shifting smooth and extends the life of drivetrain components.
