Many bikes on the market suffer from harsh bottoming and a general lack of support deep in the travel while using a coil shock. Most manufacturers will remedy this by using an air shock for ease of set up and the inherent progressive nature of an air spring to counter act the linear rear suspension action of particular bikes.
Race Only Springs have finally produced a progressive shock spring to give every performance benefit with zero drawbacks. These springs have all the same pedigree as their fork springs, produced to the absolute highest industry standards. With a spread of 7 rates in 25lb increments, and a progression at 70% travel, these will transform how your bike handles.
