RDL saddles are a truly custom made saddle, no two are alike, they are made to fit you and your anatomical requirements and can set you back as much as you want or at lest until you run out of seat pan to build on and as far up... well the sky is the limit, on one of my Runes the RDL on it is over 8" high from stock. The RDL on my F6B is 4" up and 3" back, a perfect fit for my 6'5" 400 lb., 36" inseam frame.
