I replaced the very comfy for short rides Serfas saddle with the stock one yesterday, it is narrow and has very little padding and I was better off after the ride, 2 hours and 15 minutes at a leisurely pace. Looking forward to trying out the B17 when it gets here.
Berner had the same sort of issue that I am experiencing I think.
I am mostly a skinny guy with a big gut. Have always worn low rise pants, have a skinny butt and my belly will hang over my belt. I weighed 130 pounds when I was in my early 20's, ate like a horse and never really gained any weight until I was pushing 40. I would like to get down to 180 this year. Those shorts that canklecat mentioned look intersting but the waist might be too high on them for me. I will think about it a bit before I order them.
I've read many claims of leather saddle owners that they no longer need to wear padded shorts, that would be incredibly nice if it prooved true for me one day.
