Finish Line The Grunge Brush chain brush
Chain and gear cleaning has never been faster or easier. Clean the chain with the horseshoe-shaped bristles on one end of the Grunge Brush to clean all four sides of the chain. Use the long bristles on the other end of the brush to clean components such as sprockets, derailleurs, cranks, etc.
Spray the brush with cleaner, for example, run the chain through the Grunge Brush and you're done.
