I had detailed logs of bicycles starting in 1981, but due to several moves, have lost some of them. I haven't had good luck, I've broken several bicycles for different reasons.

The two best bikes I ever had have lasted over 30,000 miles each. From what I can remember, and 15+ years of logs, I've probably ridden 200,000 miles, almost 50% of that between 1981 and 1989 and one of those old "steel" bikes was still being used until last month, but it's frame was failing. (oh and by the way - that's like 4 "groupo-s")
