i think it's not just a weight thing - height and body type has a lot to do with it, imho. sombody 6'6" that weighs 200 lbs isn't a Clyde, they're just tall. a buddy of mine in college would have probably been a Clyde, and he didn't weigh 200 lbs - only 190 or so. but he was 5'2". wasn't fat, just built like a tank with broad shoulders and a lot of muscle - kind of square, actually. if he rode, he'd probably break "normal" parts all the time - if they were chosen for the average cyclist his height.
