I wonder with those Audi drivers, will they keep their vehicles indefinitely, or is it they purchase them for a time and then move onto something else.
Cracks in aluminum body skins on vehicles, yes, I have seen that on a vehicle I once had, an at that time a 37 year old Land-Rover in a place known for 'drumming', something that happens when the panel gets dented as most of them were if they did not have a check strap on the doors, as the door rebound buffer was on the front wings.
Now back to cycles, I am the kind of person that likes things to last and with that last as long as possible, as I get used to things and comfortable with them and with that comfort I don't tend to let things go very easily which can be a problem sometimes, but still my mind is from a pre throw away society, even make-do-and-mend where I purchase fit for purpose and maintain, what drawbacks there are I just live with, because nothing is perfect. Now fine if others like aluminium and trust it, good for them, but myself with an interest in metallurgy I question the use of some metals and with aluminium, some alloys in some specific applications, although I know where aluminium alloy is used, the oversize thing comes into play often for safety, perhaps there indicating something and I know from the aerospace, industry, the ''made from aerospace materials'', doesn't mean a great deal and only would mean a great deal if that object was made by an aviation manufacturer to aviation specification and there carry the aviation specific certification and price tag to match. But if aviation alloys were to be used, what would be the point bearing in mind those alloys were developed for a specific use; aviation of which cycling is not, but could in cycling fail through not being used for it's intended application.
Oh yes, steel does fail, but usually steel gives some indication something is amiss before it does fail aside from just plain overloading which might or might not create a crack or complete failure, but if one has overloaded steel, one has to question the use they are putting that steel to, which usually amounts to abuse, abuse anything and it stands a likelihood of failing and so on your head be it.
But the trouble with purchasing pre owned, if one does not know what that thing has been subject to before a kinder person lavished care and respect on that item, but one thing with ATB's, chances are they have been abused at some point in their life and in the case of race specific objects, hammered to within an inch of their life as is particular to those that compete, where that object to them is a tool, an aid which fulfils a requirement until it fails or is replaced by something better. And there aluminium, race specific aluminium what stresses has that aluminium accumulated over it's life time, and how much more stress can it take before one day it just cracks. Now fine for the posers that bought race specific machines bitd and just pootled around as is usual with leisure cycling, maybe an aluminium race object may last and last a good long time too there giving the impression aluminium or expensive aluminium will always be good to go, but maybe the reality is the past life of that aluminium.
