This is the Finish Line Grunge Brush. The Grunge Brush makes chain and gear cleaning a breeze! Keeping your drivetrain clean helps to increase the useful life of your drivetrain and helps to prevent premature wear of critical and expensive components. Use the horseshoe shaped brush to clean all four sides of the chain, as well as the chain rings. Use the long bristles on the other end to clean the cassette, derailleurs, and pulley wheels!

Grunge Brush can be used dry in between rides, or with a cleaner for a deep cleaning. Use it with a citrus based chain degreaser or multi bike degreaser by simply spraying degreaser onto the chain or directly onto bristles. Grunge Brush scrubbing action, combined with a chain degreaser, will make it easier than ever to keep your drivetrain looking like new!

Finish Line Grunge Brush
I bought this thinking it should help keep my chain clean between rides. It has since become one of my go to tools that I use after every ride. I use it to clean the dirt off my chain, off the derailleur pulleys, and off the chain rings. The long straight bristles can also be used to clean the dirt out from between pivot bearings! I used to get 20-30 miles out of a thorough chain cleaning when its dusty and I was cleaning my chain after every two rides to keep it from squeaking. Now, I run my chain through it after every ride and have more than doubled the amount of miles between cleanings. This cheap little brush is worth its weight in gold for any cyclist, but especially for mountain bikers. It helps more than I ever imagined.
