I have used Progressive shocks on numerous bikes. Have them on my present one. Have always been very happy with the quality and performance. They may not be Konis or equal to some of the real high priced brands, but they do the job pretty much as well as the original stock ones or better. And the pricing is much better than OEM.
Unless you are a serious canyon carver or weekend racer, the Progressives will work fine for most bikes.
