frame longevity. In comparing steel,aluminum & carbon fiber which would last the longest.. I am considering purchasing a carbon fiber trek 5200 for racing & nice long training rides & I am concerned about spending that much money on a frame that might not last?? any advise or first hand experience??
not that easy....dave

You can't lump all frames of a given material into categories of longevity. Every frame is unique. Even two "identical" frames may have a significantly different time-to-failure. Manufacturing techniques vary greatly among frames of the same material. Compare Colnago, Trek, Kestrel, LOOK and Calfee carbon frames, all are constructed differently.

That said, Al frames seem to get the worst reports for failure, but it's mostly due to the obsession for light weight. As the tubes get thinner and thinner, the chances of failure, particularly at weld joints, increases.

You won't find a brand or model of frame that someone hasn't had fail prematurely for some reason.

Good old lugged steel will probably deliver the longest life, providing you don't let it rust.

If longetivity of the frame is a major concern of yours, then perhpas you should investigate the warranty of the particular fram you are purchasing.
