I think the crux of the issue is not how long a carbon frame can
last- of course there are old carbon frames out there, being ridden
today.
I think the point is that EVERYTHING fails eventually under sufficient
stress- the million dollar question being, when something does fail,
how does it do
Many years ago when I lived in Davis, a local rider knocked his top-
tube mounted pump loose while riding along. It jammed into the front
wheel, sending him over the bars. He died on the spot. I knocked TT
mounted pumps loose a couple of times myself while reaching for a
bottle or a shifter. I

It does worry me a bit that we're starting to discuss carbon fiber on this
list. But, it has been specifically related to Riv/Grant topics, so I am
wont to say it's outside the fence. But, it's leaning against it, eh?

I don't think anybody suggests that EVERY carbon frame or fork will fail in
the next XX years. In fact, probably a TINY fraction of a percent MIGHT.
I also don't think that EVERY Toyota on the road is going to accelerate
unexpectedly and uncontrollably within the next XX years either.

Very good point. It up to each of us to evaluate the risk versus the
reward and make a decision for ourselves. If, in fact, carbon is less
forgiving than steel, which I believe, then I thank GP for making me
aware of this information. Don't shoot the messenger of bad news.

I believe the Davinci, a very nice triple, is listed at a modest 158
Q, and the design allows for a very short bb, which makes it easy to
move between a dbl triple. BTW, they are made by White right here
in the US, or at least in Ca. Not cheap, but less than TA.

That would have been nice, especially since I'm at LAX Radisson at the
moment (with a bicycle in my suitcase). When I visited Riv last year I
didn't get to meet Grant so it would have been a hoot to meet him a year
later (especially now that I own a Riv) almost exactly a year later. :-)

engineer who claims to have great familiarity with carbon materials,
