hmmm, I have almost 9k miles on my Trek 5200 frame, I have weighed between 190 and 220 for all of those miles. I bunnyhop RR tracks, potholes and cattle guards. All of that without a single problem from the frame. (or the wheels btw, Mavic Heliums) As for power output, I dont know, but at times when lifting I was squating over 400 pounds so I figure I'm puttin' it to the bike during sprints.

I'm sure there are other stories out there that should work towards debunking the belief that CF is a 1 season frame material.
