...new bars are made by a different process, because they are a different, modern aluminum alloy.
I have pretty good health insurance, and it covers a lot of facial reconstructive surgery. But I'm on my own for the dentistry that accompanies it. So I toss a lot of olde aluminum bars, even when they look relatively straight. I like the idea of having that reinforcing sleeve right at the stem clamp. But I broke a bar once (half tore it, actually). It got my attention, and maybe until you do that it's hard to understand how frightening it is.
