One thing that a few of respondents in this thread might be unaware of is that CF bonding techniques and technology have changed significantly in the 45-50 years that they have been developed, and will continue to. In the last 25 years it has started to become significantly more common. When a technology or material matures, it becomes more available, cheaper to utilize, more versatile, and more reliable. Do you really think that today's high quality CF composite bikes are really designed/manufactured like a Specialized Epic, Giant Cadex, Vitus Carbone, or Trek 2300? I doubt it.

Some obvious relevant developments since that time might be:

- Better resins
- Better bonding techniques
- Better molds
- Much better joining techniques
- Better resistance to ultraviolet light.
- Better understanding of where reinforcement/increased wall thickness is necessary as it applies to the physical demands of cycling
- A better understanding of what carbon fiber's limitations are; including, what shapes it can be molded into, and how distribute loads at critical stress points.

You see, we can't analyze 25 year old bikes to see how long the current bikes are going to last. The best current CF bikes are make with processes and techniques that are only about five to ten years old.
