This is a bit of a downer but an interesting thing to keep in mind especially for you guys on vintage bikes, poor bloke lost his life due to stress fatigue in an aluminium steerer tube. You always hear horror stories about carbon failure but even in cars it does age very well, it was an initial manufacturing flaw plus years of use and time that caused the metal to fatigue and let go on him when he needed it.
Even though I'm on the upper limit, being an engineer I really do have a lot more faith in carbon parts than I ever will in a lot of alloy for just that reason.
