Sound like complete and utter BS to me. We all know about fatigue failure in aluminum, but that doesn't happen if it has never been loaded. And aluminum doesn't corrode with age, at least no more than a few microns at the surface.
Not a metallurgist, just a chemical engineer, but I usually know BS when I hear it.
> In the latest Rivendell Reader, #30 (I'm sure you are all subscribers, right?), Page 14, in an interview with the President of Nitto, the question is asked about whether aluminum handlebars should be replaced every five years, even if they have not been crashed. The answer says that if you have an aluminum handlebar that is ten years old and never used, that it will be "significantly" (quotation marks added by me) weaker than when it was new. Anybody know why this would be? It doesn't make sense to me, but then, I'm no metallurgist, just a rocket scientist.......Lou Deeter, Orlando FL
