I have done many Mods to my bike. The 16t Replacment came from Dennis Kirk, very Fast and the Quality of the product was great. Highly Recomended. You can't go wrong with Dennis Kirk replacement Parts. Excellent Service and Fast Shipping. They definately have earned my repeat business, when I need something for my bike! Thank you.
