Carbon durability according to Canyon?

Another thread on here gives a link to Canyon bikes where it states that carbon frames and other components should only be used for 15000 km or three years. Its easy to say 'well they would say that wouldnt they' but what is the science behind this? Its actually not necessarily in their interest to say this as it could put people off buying their frames at all. There must be a reason.

They dissolve after 15,000km. Imagine if you hit the 15k mark on the road???0

Doesn't bear thinking about
What they are saying seems very strange. There are plenty of horror stories around about carbon but balanced by destruction testing which shows it to be every bit as strong as aluminium and then some. They seem to be suggesting there is a fatigue process but I don't know where the evidence for this comes from. I've just googled but can't find anything indicating that carbon suffers like this. It is degraded by ultra violet but I wouldn't have thought this would be a problem with a painted frame.

Speaking from the perspective of a tennis player carbon does degrade over time with use. The constant flexing of the fibres changes it over time but I would have thought 3 years was a short life span. The bike would still be rideable, just feel a little different.0

i see this as either a bit of arse covering by the manufacturer or a damn good reason not to by a canyon.0

Love these quotes from Canyon
Canyon gives no guarantee or accepts no liability for the any of the information contained in this Technical Support Center.
Never leave carbon in your car on hot days.0 -
I know with carbon fishing rods, their action gets softer over a long period of time. Dont know whether the same applies to bikes in a similar manner ????Canyon Ultimate CF SLX 7.0

there're some wildly divergent manufacturer statements about cf durability here...

Well, I'm relieved I bought a Look - that can be used for 100s of years whereas Canyon only lasts for three. In your face, CanyonFaster than a tent.......0 -

Maybe this is more geared to their MTBs? My 2006 Giant TCR still rides close enough to how it was when new for me not to notice any difference. Could be I don't ride it hard enough to degrade it.
I know guys who ride 10 year old OCLV hardtail MTBs and they've not delamed spectacularly. Don't understand the hype.The titifers have sung their song.
Now it's time for sleep.0 -
I'm riding a Trek OCLV bought in 1999.
Trek also do a lifetime warranty which covers frame and forks, and they honour it.0 -
It's liability concerns gone a bit mad. Ultimately carbon is still quite new and its make up has also been evolving slightly in terms of lay ups, fibres, etc. Given no-one has 30 year old examples in the wide some of the manufacturers are being cautions. Canyon overly so.
Given they are making Boeing aircraft out of carbon now (and I suspect the airlines are anticipating more than 3 years use out of their shiny new 787's) then I suspect we don't have much to worry about.0 -
Bit odd as they give a 5 yr warranty on their frames do they not?0
-
Actually, its 6 years0
-
given the recent delivery delays I would suggest ordering your relacement Canyon today - should be delivered just as the old one disintegrates in 3 years time0

As a keen tennis player myself, I'd also say that carbon composites can subtly change in their feel with rackets generally feeling a little less 'crisp' after a certain amout of time in play. Some people actually prefer the feel compared to new rackets of the same model. I would say though, that a tennis racket receives a hell of a lot more abuse than any road bike frame in normal use, but I still use tennis rackets which are well over 10 years old and they play fine.
I do wonder at Canyon's claims about a 3 year life for their cf frames. If carbon really has such a short useable life, then nobody would buy a Bugatti Veyron, Mclaren 12C, etc. Some Ferrari F40s and Mclaren F1s are over 25 years old and 20 years old respectively and they are as good as the day thet rolled out if the factory. Theoretically, as long as a carbon fibre structure isn't subjected to loads which exceed it's design spec. then it should last indefinitely. This is assuming of course, that it's been designed and manufactured correctly in the first place.
All of which leads one to conclude, that Canyons cf frames must be terribly built if they feel the need to say they need replacing after three years. I'm not saying this of course, as they have a great reputation.0 -
Given they offer a 6 year warranty I will happily have Canyon replace mine after 3 years, gratis of course0

They say aluminium frames should be changed every five years.0
