Seeing as everyone is throwing in their 2 cents...here are mine. I love the performance I now have after installing the Freak. I am no grease monkey but enjoy tinkering on things and get satisfaction when things work out well. I am very satisfied with the outcome of the Freak installation. It took a good while for me to install, but I did it so the instructions and hardware supplied work fine. To date, I have not had any problems with my chain rubbing the tool box either. I check it now and again because I keep reading about the problems others are having with it. The thought of stainless or aluminum for the brackets would be a great improvement for longevity though. Anyway, as the commercial goes....18 Tooth Sprocket $20, Freak Kit $295, HUGE SMILE on my face riding my black beauty around town PRICELESS. Thanks Brent. My 2 cents anyway.
