If I would have been shown that "Condition 1" statement that I posted earlier in the thread at my LBS, where I should have seen it, that information would have certainly changed some of my decisions. I can only hope that passing that knowledge on to others might help them in the future.

I guess because I ride road bikes. And every time I walk into a bike shop to look at new bikes, they tell me why the latest and greatest carbon fiber race bike is exactly the bike that I need. It's important to me to stay up to speed on the current bike build trends so I will be an educated buyer when the time comes again.

I can only assume they did and were told it was fine and not covered by warranty. Which has to suck to hear.

Bike Shops tell you this because that is mostly what they carry and since they tend to be in the middle to high end pricing they make more profit than selling some "cheap" aluminum bike. They're only after your money. That sort of thing has been the history of LBS's, when aluminum was the big thing they bragged on those too, when steel was the only thing you didn't have much bragging room except for lugs vs fillet brazing, then the argument was more about components and weight...like today.

Factory car and motorcycle race teams regularly rebuild engines after every race, with mere hours on engines run for less than 1000 mi. However, the warranty on drivetrains in the vehicles they sell to the public, through dealerships, is measured in years and tens of thousands of miles.
What does manufacturer advice to racing teams have to do with product sold to the public...? Factories aren't concerned about personal injury, they're concerned about bad publicity...

With these bicycles you are in a completely different world. The C40 was EXACTLY the same as used in the Tour de France or the other grand tours. It also held the record for the number of classic wins.
The reason that the lawyer stated that these bikes were supposed to be destroyed at the end of a season was because if the teams sold these bikes they assumed personal liability. Even though in Europe this is sharply limited it can still bankrupt a team and give their sponsors a bad name.
What are the bikes that are sold? The one's I got were the team bikes that were never used. With no marks on the brake mounts or the drop-outs they're pretty easy to recognize. Sponsors will buy and entire group of framesets and at the end of a year there are leftovers that were never even painted. These are usually stolen by the mechanics who sell them for what they can get since they are paid a pittance to work for the teams. That is usually a given.
So the advice given to the teams varies from what Joe Citizen Purchaser should have ONLY in the level of riding. A one year lifespan on a bike used in the spring classics is about 10 years in normal use but that is only in general. Any particular bike could very well fall apart in the three year US warranty period if ridden as roughly as those in professional racing. And this doesn't mean fast, it means hitting road bumps hard at a high enough speed to generate the high frequency waves that will dissolve the resin that holds the carbon fiber together.
BUT, if Mike takes Colnago to court over that failure of his it wouldn't matter if that frame was 100 years old - catastrophic failures of that sort are NEVER supposed to happen on any goods sold in America. Most especially since the working life of the frame is not mentioned anywhere in the manual.

Plenty of anecdotal data all of which is meaningless in terms of determining how frequently carbon fiber fails. As to 'catastrophic failure' so many of the broken carbon fiber frame pictures have an attached story about a prior crash that the owner thought nothing of that it is hard to take anyone seriously who claims their frame failed while just riding along.

Bike manufacturers seem to accept "Grey Market" bikes not intended for importing into the USA. But, if the bike was originally a team bike, then one may argue that it was never intended to be sold to the general public, and thus limit liability. Also, no matter the skills of a home mechanic, was it "professionally built"?
So far I haven't had a critical carbon failure. My Chinese Seat failure (earlier in the thread) was more or less an incidental finding (JRA). Once I discovered it, I rode the 10 miles home and took it out of service, at least until I'm satisfied I've repaired it.
I have a Canadian CF seat that I'm still using. My only complaint is that it squeaks. And, may try to fix the squeak so it doesn't obscure some other more important noises from the frame. But, the goal is to pay attention to the bike, and hopefully discover any faults before they become critical.

Well, let's get something straight - the engines and the entire rest of the cars ARE NOT what are used in racing. And while many basic components such as the engine blocks may be the same they are never operated in even a close manner to what a race car undergoes. "Rebuilding" a race car engine usually consists of pulling the old motor and inserting a new because for one thing - these engines are hogged out to the last CC allowed for their classes so you cannot "bore" them to get a smooth surface for the new rings to run on.

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.

Their desperate grasping at any out-of-context remarks or web pages that could possibly support their illogical view on the topic gets pretty sad, honestly. I guess most of them haven't been around the industry long enough to remember that, when steel frames racing frames were common, so were broken steel frames. I know because I have broken several myself, and seen many more broken.
As for you, Jarret2, you must know that the 'racing bikes are fragile' statements does not exclusively refer to carbon... well, you should know, as long as there is no reason you have to deny this reality.
Happy riding!

Yup, the local race team gets new bikes every year and they sell the old ones. Haven't heard of any asplosions.

The pro road bikes, well at least Canyon does, but I heard others do to, are all put through a CT scanner before they are sold, so there are precautions taken so as not to sell a bike that could endanger a rider.

Have any reference? Sounds like a reasonable precaution. If the price was right I would buy an old 'pro' bike without thinking twice. If I could afford it that is, I don't see myself moving away from aluminum any time soon.

Not that part. The part that is a joke is that because not a single one of those has failed (allegedly) that somehow means that steel is excluded from 'as we make and buy lighter and lighter bikes we expose ourselves to greater and greater potential for a major problem to occur.' Curiously, you later agree that 'usually lighter stuff will fail sooner.' So, do you think that last statement, which you made, not me, applies to steel or not?

'However, Canyon still offers customers their normal six-year warranty with sales of the ex-pro team bikes, while Condor offer two.
“Every single frame and fork has to pass through our in-house CT scanner here in Koblenz so we can examine if there has been any damage to the integral carbon structure beyond what the naked eye can see,” said Leake. “If we find any evidence of damage then the parts are rejected. We want these bikes to be ridden, not placed on a pedestal just to be looked at. Anything unfit to ride is certainly unfit for us to sell.” "

What I said was that there wasn't one report that a Rodriguez bike frame ever failed, not including crashes of course. I think that a lightweight steel bike if made properly like the Rodriguez appears to be made, the failure rate will be lower than with a carbon fiber bike in the same weight range.

Ever wanted to get your hands on a pro's bike? Here's how - Cycling Weekly About 2/3rds the way down it says this:

Slipstream Sports would sell the team bikes at the end of the season when they were with Cervelo on their webstore. I remember seeing Thomas Dekker's and Andrew Talansky's bikes on there. They had frames and complete bikes with some base Mavic wheels. You can see scuffs and scratches on the components from the wear and tear.

Would a CF frame owner benefit from regular or semi regular frame inspections, say, once a month or so?
Or can CF frames break down internally and fail suddenly even when there is no sign of fatigue externally?

I honestly wouldn't know. It's actually an interesting topic: which material allows you to build the lightest with the least compromise in durability. I mean, at some point things will get too light to be workable regardless of material, I just wonder how quickly different materials reach their limit. Might look into it tomorrow. 
Sweet, cheers.

Sweet, cheers.

Also note what they say about manufactures claimed weights on their bikes and how they get those figures, I often wondered this because I ran into a guy that bought a Trek (I can't recall the model but he paid $4,500 for it) CF bike that claimed it weighed 14.7 pounds but actually weighed a pound more which is a pretty hefty jump in weight, he was actually telling me he was pissed when he found out but couldn't do anything about it because he had the bike for a year.

Canyon only continues to offer the warranty after running the frames through a ct scanner.
Not a good sign and I wonder how many get rejected?

How is NOT a good sign that Canyon checks there Used racing bikes thoroughly before selling them? That shows care for safety and attention to detail.
The point you refuse to acknowledge is that Not only do they sell their used racing bikes---They warranty them for another five years!!
The question is a totally dishonest question. You do not "wonder" how many, if any, get rejected ... you are using this question to imply that most of the frames fail because, you know, CF is deadly and only lasts two years, or not even if raced.
If this is a regular program Canyon runs, it has to be profitable, which means the CT scan and the warranty service have to be covered by the cost of the sold bike. Since these bikes are sold to be ridden they cannot cost a Lot more than a New Canyon frame, or the buyer would buy a new frame with the full six-year warranty.
If you really cared, you would call Canyon, as apparently Rekmyata did.
In case you missed it here's the facts: Canyon Sells it used racing bikes To The Public and honors the same six-year warranty all their frames get.
Right there that shoots down the notion that CF frames are only good for two years or one season of racing---because ALL Canyon frames come with SIX-year warranty.
In case math is not yuor strong suit, Six is more than Two or One.

It is quite apparent that there are two classes of posters here. Many of us are in one class that thinks CF bikes are not the ultimate bike for 98% of the riding public. The other class is the people that have drank the mfg koolaide that say CF bikes are the greatest thing since sex. They are the ones that have paid out huge bucks, and dont like anyone that says anything against there "baby".
To show you that it just comes down to money, on one of my bike forums a guy was bragging that he bought a $12,000 CF bike for $7500. It tells you that there are huge profits involved with CF bikes. You know that at $7500 the mfg and the bike shop still made money.
