I haven't tried bibs yet, but I don't have to adjust my new Cannondale's. With my old shorts, I had to keep on adjusting them and stuff because the legs and waist weren't that tight, and the chamoix was a thin as a cigarette paper, but now that I got some high end shorts, I haven't had to touch them yet, except for when I pulled my cellphone out of the ass pocket to call for a ride after I got my 2nd puncture of the day. I'm NEVER going to buy Continental tires again.
