I don't think I've tried the Specialized butt-o-meter, but with Bontrager's you are not supposed to wear bike shorts, you're supposed to wear street clothes, preferably something with thin fabric. So I'm wondering if they measured you wrong. (Also if your sit bones are that wide, you would have had different problems with the Jett 143.)
Have you tried the Lithia before? How wide is it?
