Our all time, best selling model made with WaterShed leather and Chromoly rails. The patented shape of our slot allows the saddle to move with you. We call it Flex-Fly. It reduces perineal pressure, sit bone pain, and saddle sores. This saddle has no break in period. It feels good from day one. This is the saddle for all but the most petite long distance riders, up to 250 lbs.
