So ... more BS from the "CF bikes killed my mother" crowd---the same crowd which adds bits about a two-year time frame and then passes it off like it wasn't a lie. Well, I guess I have been "educated."

Yes, it is easy to find (https://media.specialized.com/suppor...0000057489.pdf) and easy to see that it explicitly does NOT only include carbon fiber bikes:

I went out for a four hours ride on my Colnage EP ( over 2 years old ) this morning . Went up and down steep and not so steep hills , smooth and broken roads . I would like to tell everyone that I am still alive and well after the ride .

This stuff cracks me up. Pun intended.
Everyone seems to know someone with a cracked carbon frame. The manufacturers post warnings about them in the owners manuals about how fragile they are and how the owner should not expect a long product life. Right there in black and white. Then we see correspondence with the manufacturers themselves where they say they only use them one to two seasons and dispose of them or sell them with a disclaimer that the bike might be unsafe due to the unsuspecting catastrophic means of failure that routinely results when they break.
Yet, people come out in droves to defend carbon road bikes as if they are the most safe and durable options on the market for every rider. Complete cognitive dissonance or just Internet trolling. One or the other, I guess. Maybe a little of both. I guess most other rational people have given up trying to offer a differing opinion here. I should probably follow suit.

You made a good point... in the wrong direction 
Auto racing teams don't sell race cars to the public. In fact, I would be willing to bet that only a handful of car owners base their purchase decisions on the success of auto racing teams, if any. The marketing to consumers has nothing to do with race results.
The road bike industry is different. The whole carbon road bike line up is driven by racing. They build a bike for their pro racers to use, then turn around and market the same bike to the consumer saying this is a winning race bike. And people eat it up. Just look at the number of people in this thread that are non racers riding pro carbon road race bikes.
And those same companies turn around and post a blurb in subtext 39 of appendix B in the owner's manual about how carbon road bikes are built strictly for racing for in one or maybe two seasons, use light components that have a known shorter use life and weight limits that rarely see the light of day.
Most people don't read that stuff. They just want the fastest bike on the floor and expect it to be as durable as steel and last for years without issue. And they are surprised when its not that way for them.

Failure on both sides. On the part of consumers, the vast majority of whom are recreational riders, who are foolhardy enough to believe that a few ounces is an any way shape or form discernible in terms of performance gains.
And on the part of manufacturers who fail to educate consumers about the risks inherent in CF frame failure.
Bicycles are so simple: 99% of riders ride for fun and exercise. The alleged benefits of a three ounce weight savings of a carbon frame can't possibly outweigh (no pun intended) the additional risk of catastrophic frame failure once it reaches it's fatigue limits.
There is the question then of the use of ubiquitous carbon forks. There seem to be fewer threads about carbon fiber fork failure. Why is this? Are CF forks inherently safer than CF frames? If so, why?

Because even (most of) the trolls have accepted that carbon fiber forks are lighter and just as durable as metal ones while offering a better ride. Eventually they'll accept the same of carbon fiber frames. Change takes time.

The very warning you posted and keep citing distinctly does NOT say anything about how long the bikes last, and distinctly DOES list several metal frames. Yet you still claim that it states "in black and white" exactly what we can all see it does not say.
If you are a troll, I praise your subtlety. If you are serious, I seriously recommend counseling.
Oh,a nd by the way ... anything official from Colnago would be on Colnago letterhead, no the stationery of some possibly real/possibly new/probably ambulance-chaser lawyer with a home-made web page. i can guarantee you Colnago has lawyers on retainer---can't do business without them. So if some guy claiming to be associated with Colnago with a homemade website responds, he is Not speaking for Colnago. I strongly suggest the OP contact Colnago and get clarification on that if he doubts it ... but i strongly believe this whole thread is a troll.
"The damage I sustained in the accident caused the accident."
There is a thread about physics and cycling ... this needs to go there, because apparently Colnago frames can warp time.

I do wonder, however, if people watch some of the rally races... at least for inspiration, for example the Paris Dakar (oh, did they drop the Paris?). Still somewhat removed from ordinary driving, but if I was interested in serious off-road driving, that is one race I'd watch.

Most riders simply don't need the expensive bikes they ride. Racing components are not always the most suitable and durable for daily use.

I don't see many saying they are the most safe and durable option. What I do see is a lot saying that used as directed, they are a perfectly reasonable option for recreational riders. The most durable option is probably always going to be a Schwinn tank, if we want to be realistic.
Certainly the Indy 500 or Formula 1 cars are quite far removed from road cars. Even stock cars in the USA aren't so "stock".

There's something fishy about the OP's story and the Colnago lawyer's letter. But far-fetched or not, it does something that's popular in politics now- create an element of doubt, preying on fear.
Setting aside the danger, it does makes me wonder about the high cost and short lifespan of carbon bikes, particularly high end race frames. They can cost from $3-12K+, and Colnago's can be 6K just for the frameset! It may well be just fine 5 or 10 years from now, but will rapid obsolescence and questionable durability, the depreciation is terrible. If you get your bike free because you race, or have money to burn, great- but what about your average weekend warrior?
There are plenty of steel bikes from the 70's, 80's, 90's, still going strong- somehow I don't think we'll have vintage carbon 20-30 years from now

What I wanted to say was that most cylists, probably can't ride even my 400€ road bike to its limits, even if they're riding a 3000€ top tier bike.
Don't misunderstand me, I'm ok with people riding whatever they want. I also have (relatively) expensive bikes, and bought them because they make me happy, not because I'm able to ride them like a pro.

Agreed, just like the folks I know that like to toss racing parts on their daily driver cars. There is a cool factor, there is generally little useful or practical feature.

Comparing steel bikes from the 70s (as in, any steel bike) to high end race frames of today is not a very fair comparison. I'm sure plenty of bikes made these days will be around in forty years, the 14lbs superbikes probably won't. That's the beauty of having options, anyone gets whatever they want.
With all that said, suggesting that CF bikes (all CF bikes) are made to last two years is preposterous.

Of course. My own bikes have limits beyond my abilities. Even my 400€ alu with steel fork entry level road bike.
What I wanted to say was that most cylists, probably can't ride even my 400€ road bike to its limits, even if they're riding a 3000€ top tier bike.

I'd argue the point that there are very few heavily ridden steel bikes from the 70s, 80s, 90s or even 00s that are still being ridden at the same rate. Bikes last for decades hanging in a garage collecting dust. They don't last for decades of 5,000-10,000 miles a year on the open road.

You see most people here aren't defending carbon frames as much as they're defending their right to choose whatever bike they want.
