I am happy to announce a new sponsor for 2013. Dualratiosprocket.com is a new product available for most common bikes used for stunt riding. It is a product made to be able to use two different gear ratios all by switching a few bolts, It is like having a stunt gearing and street gearing on your bike at all times! This product saves you from having two sprockets, chains, cush drives and the time to swap it out! The craftsmanship on this product amazing! Take a moment and check out www.dualratiosprocket.com
