This is a part of bike fit that I find frustrating. Saddle makers typically give you only the width and length of the saddle. But those two dimensions tell you almost nothing about how the saddle will work for you, except for comparing two widths of the same brand/model of saddle. The most important dimensions, in terms of fore/aft fit, are 1) where is the point of butt contact with the saddle relative to the center of the clamp area of the rails, and 2) what is the length of the clamp area of the rails. I measured these on the small collection of saddles I have and they vary widely - we're talking centimeters, not millimeters. If you have a saddle with a 35mm clamp area and a seatpost with a 25mm clamp, you have +/- 5mm of latitude in fore/aft placement. You can change your fore/aft placement by 20mm, easily, swapping to a different saddle. Good luck finding that out without first laying out the cash for that saddle! And, on the post topic, I second the vote that saddle position relative to BB has made a fair amount of difference for me in finding long-distance comfort. Also, I have found that fascial counterstrain PT has made an enormous difference for my comfort on the bike, correcting a long-term hip tilt and associated issues, as well as helping recover from a couple of compression fractures in my vertebrae. After a couple of treatments I felt symmetrical on a bike for the first time ever. In my experience, pain issues have developed over time without me really recognizing them until they get to the point where I can't ignore them. So, I've gone for extended periods with bike fit issues that took a while to manifest into real discomfort.
