"Also, I read some somewhere(maybe a Riv Reader) that metals, and aluminum in particular, weaken significantly with age."
I'd like to see the article and review the evidence. I myself have heard nothing said about age as such making metals generally, or aluminum in particular, less strong. Repeated bending, corrosion, yes, but not age alone. Anyone? Come to think of it, Jan in all his riding of vintage machines from 40s and 50s has said nothing about their period cranks being dangerous. Patrick Moore, who rides old aluminum cranks (and very old aluminum cranks! 8 sp Logic, 5 sp Pro 5 Vis, Viscount/Lambert -- the one with the tapered socket) and doesn't want to switch. -- You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.
