I hate being serious, but.......

One of the best things I did was put together an alu "training" bike with some
of my older parts -- perfect for days like today. It ain't gunna rust, so I don't have to clean
it if I don't want to, and the parts are kinda old..so.......

Good excuse to get another bike. Your other bike is steel, right?

Perhaps you could get an alu frame and switch the stuff over.
