Qoute: 2/26/10 Update- The article below was written back in 1996, 14 years ago. It's still relevant, but since then we've seen the super-light ultra-performance carbon frame move into moderate price levels. It no longer defines the extreme high end. That's good news, but carries a warning. You cannot build a 2.5 pound carbon frame as strong as a 3.5 pound frame. The tube walls are thinner, and when even the highest-quality-possible construction (as found on Trek's OCLV product), the can still easily damaged by forces not normally encountered when riding. Blows to the side of a tube, for example, will likely cause them to crack.
Normal riding isn't an issue; the modern Trek OCLV will likely outlast frames made of any other material. But making them so light, so comfortable, so efficient... there is a trade-off in durability when abused or crashed. We recommend a very thorough inspection of crashed frames of any material, but carbon even more so, because it's difficult finding under-the-surface damage. Riding a frame that has been crashed could cause unexpected failure down the road. Please, if you have any doubts, bring such a bike in for inspection. We cannot guarantee that it's perfect, but we may be able to find an indication of trouble that others missed. --Mike--
