I too, had the Softride stem mounted to a mountain bike. It worked very well and did what it was intended to do, take the edge off the bumps. I only ride road now and no longer use a sus stem. Have arthritis in the wrists and elbows so I run 28mm Conti at 90psi along with Serfas gel pads under the bar tape. Must point out the frame is custom built for my body and this resolved a lot of the issues I was having in the wrists and back.
