Finish Line Grunge Brush

15⁹⁹

Now with an improved ergonomic design! Chain and gear cleaning has never been faster or easier. Scrub the chain with the horseshoe shaped bristles at 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 like sprockets, derailleurs, cranksets, brakes and pedals.

Regular component cleaning prevents premature wear and tear on chain and sprockets, eliminates chain skipping caused by dirt and grunge, and assures smooth operation of drivetrain and brakes.

The Grunge Brush™ can be used dry or for deep cleaning action, use it with Citrus Bike Chain Degreaser or Ecotech Degreaser, by simply spraying degreaser onto the chain or directly onto bristles. Grunge Brush™ scrubbing action, coupled with a Finish Line bike degreaser, will leave your drivetrain looking like new!
