The Grunge Brush
The Grunge Brush enables you to clean your chain with ease. The three side bristles allow you to clean all four sides of your chain and the long bristle side lets you clean other parts of your bike like sprockets and wheels. Regular component cleaning prevents premature wear and tear on chain and sprockets and assures smooth operation of the drive train. The bristle blocks are adjustable to accommodate all sizes of chain.
