A 1990 Kona Cinder Cone frameset won't wear out (in normal use).  Anything with suspension will, and you won't be able to get parts 30 years later.

Same goes for carbon stuff.  No-one will be collecting *and riding* it decades later, because it won't be safe, the integrated headset will have ruined the head tube or the PF30 bottom bracket will creak like a vampire's coffin lid  ;)
But presumably you'll be able to replace a worn out suspension fork with a new fork of compatible length, which will probably work better anyway. Rear suspension might be a problem. And press fit bottom brackets are an abhorrence, but I'm sure I read of some way of cutting threads in them, or maybe it was some sort of insert; probably not possible in a carbon frame though.

My 80s all terrain bike, recently out of retirement. Awaiting a rear brake. The chainset is temporary.

You normally kick along then? Chapeau!!

The chainset is a double I had knocking around.  I will see if I can get a triple.

The wear in a suspension frame should be in the bushings/bearings that form the rotating part of the linkage and the shock.
If anything else is wearing out there's a bigger problem with the design.

Whether would have performed the same had he shunted it like John Watson did at Monza is another question.

What's that supposed to show? Is that a 1990s car? Or what?  ???

Woops sorry context missing:
Worlds first fully carbon fibre monocoque  F1 car design from 1981 still being raced in 2019.

Would have been baked anytime between 1981 and 1983.

Just checked, that "car" won the US gp at detroit in 1982

Realistically it's only the tub (the monocoque) that will be original but that's the equivalent of a bike frame...

I also checked the Hull life of the carbon fibre Boeing 787, at 44k cycles its longer than a 747 at 35k but that was less interesting.

Supposedly what kills carbon fibre over time is sunlight or at least the UV in it, F1 cars and carbon bikes don't tend to stay out in the sun for most of their life.

Well I would never buy a second hand carbon fibre jumbo jet  unless I was absolutely confident it hadn’t been crashed and repaired badly.
