My BiSaddle doesn’t hurt…at all. Plain and simple. I used to be in paid at about the 30 mile mark while mountain biking with other saddles. Anything over 30 miles would progressively get more painful as I added miles. I race XC MTB and my training runs normally never go over 50 miles. I recently did a 75 mile ride and when I stopped, my backside felt exactly like it did when I started. You can’t ask for any more than that.
