The back roads where I ride ,although paved, can be pretty rough. A few years ago, I lost alot of weight, and it makes a difference on the "cushion" it provides for our "sit bones" I had a sore butt after about a 45 minute ride, once I added the sprung seat, it made all the difference in the world. Whatever irregularities the rear shocks dont soak up, the seat takes care of. I had tried beads, a sheepskin cover, adding jell to my seat, etc. I had some sort of solo seat with a plastic pan at that time. The sprung saddle made a big difference in my case.
