30,000 +miles on this full carbon fiber custom tandem bicycle . . . . . . including Easton c/f handlebars, front and rear; c/f cranks; c/f fork . . .
Have BROKEN 2 steel tandem frames and and one steel tandem fork . . .
So you still ride steel**********
Anything can wear or break eventually.

It swings both ways.
It ain't just the material,
but the usage & build quality.
(thank you umd for a clear response)

Oh yeah, cracked the eyelets on an aluminum rim too.
Most of my list is crash damage. Actually I guess except the spokes it's all crash damage, although it didn't all break in the crashes. Some of those items broke after the crash. Some quite some time after.

Totally.
I'd say that those who put on more miles or who race will wear something out faster.
I'd imagine that all materials have life expectancy numbers depending on their usage.
In an extreme example, a carbon bike used as a recreational rig every other weekend will more
likely than not outlast one that is raced every weekend and trained on during the week.

Next week the UCI proclaims that all riders must ride fully lugged straight gauge Rivendells in a move towards rider safety.
Carbon safety cages in F1 cars seem to hold up pretty well.

Like the rest of the car, most of the monocoque is constructed from carbon fibre. Normally it comprises high-density woven laminate exterior panels, and a strong, light 'honeycomb' structure inside. Constructing the monocoque is one of the biggest jobs faced by a team's composite technicians. It's not dissimilar to a 1:1 scale model kit, with hundreds of separate carbon fibre components being bonded together using very powerful adhesives.

Ok, edit: Same questions, but just failures from "riding" as it was designed?
In other words, who's had their bikes asplode from just normal riding (not racing, not in a crash, etc...)?

Nothing that can't probably be traced back to damage from a crash at some point. Except for my RD, which committed suicide by jumping into my spokes when an internal (metal) bolt sheared off. So there was a metal and carbon component involved, but all indications point to the failure of the metal first.

I've had bike frames break from "just" riding, but none were catastrophic.
Steel Raleigh: cracked seat stay
Ti Airborne: cracked chainstay
Cervelo R3: BB insert came unbonded
I have not had a frame break from a crash, not even the R3 which I crashed hard at speed. The BB insert became loose some three years after the crash.

Someone around here posted pics of aluminum bars that had corroded into dust under the shifter clamps. The bar tape was pretty much the only thing holding the drops to the rest of the bar. Fortunately for him, he discovered this while retaping the bars and not after a crash.

Also, after hearing so many Thomson evangelists boasting about how they never break,
I posted about 1/2 a dozen pics I came across from a simple <5 second Google Image search.
I don't have anything against Thomson (matter of fact, they are my preferred choice for MTB rigs).

More than likely, the bars showed a bit of corrosion under the clamp, but the main feature would be the unseen crack at the clamp caused by a combination of over torquing the clamping bolt and fatigue.
