I'm still above 200 lbs. (dammit!
) but my reason for eschewing lycra has more to do with my own aesthetic than worrying about those of the public at large: I hate clingy clothing! Give me a roomy pair of cargo shorts (with a nice chamois undergarment, o' course) and a loud Hawaiian shirt any day. I may not impress those obnoxious 'serious' roadies, but I also don't have to peel myself like a grape after a warm-weather jaunt.
