The Grunge Børste

The Grunge Brush has 3 bristles, which you can slide in the holder to adjust them optimally to every chain. Its stable bristles clean the chain fast and reliably when using them while you turn the crank. With the long bristles, you can even remove the coarsest dirt from the sprocket cassette. You can also remove the bristle blocks separately from the brush in order to clean them after use.
