I have a 98 CAAD3 that is still going strong. I'm 220-245 and still use it as my organized ride bike on centuries. Some with 10,-12,000 ft of climbing. That's plenty of stress from a big body and it's still great!

Some buds have told me years ago to watch it as it may burst into flames. Hasn't yet but plenty of their bikes have. Ti, carbon, steel
