Hey folks, this is my first post. I'm a 25 year-old 300+ lb. lady who has been recently reintroduced to cycling after several years off. I just now upgraded from some Frankensteined junk hybrid to my first ever road bike (an 80s model Raleigh Triumph, nothing fancy). I've never ridden on wheels this thin (the drop handlebars are a whole 'nother thing) and I'm worried about the integrity of such a wheel under my weight. I already noticed on the way home from my LBS how much more I can feel every little bump in the road. Do I have anything to worry about? Am I likely to experience some kind of catastrophic failure? FYI I ride in the road mostly, except for when I'm on campus. I avoid jumping curbs and I think I'm pretty good at handling my bike, floating over uneven pavement, etc.
