Finish Line Grunge Brush: Hi I'm David with Finish Line, and I want to talk to you about our Grunge Brush for a moment. A lot of times people ask me, “how durable or sturdy is that?” I just wanted to take a minute to show you, this is very very durable. You can jump up and down on it, it will last a long time. The bristles are very stiff for cleaning the chain and the chain ring and the rear cog, these last a long time and people get years in years of use out of this brush. It is a very durable product. I just wanted to share that with you. I'm David, Finish Line and this is our Grunge Brush.
