20 years? Wow! Didn't realize my head was that far under a rock! And I'm probably a punk kid compared to some of you. But, my newest previous bike was a 1991 model.

I guess old fangles might include cottered cranks, Ashtabula cranks, 21.1mm stem quills, and 590 and 597mm tires. And 630mm, maybe, though I know there are plenty of folks who like their tires no fatter than 32mm.
