My '83 le tour luxe doesn't quite qualify for the 30-year club (yet), but I have wondered about the prospect of "classic and vintage" bikes once the huge numbers of aluminum framed bikes that have been produced in the last dozen years or so are considered "classic and vintage." Aluminum just doesn't lend itself to the timelessness that a well cared for steel bike does, particularly because of the properties of the material. And they're still making more aluminum frames than anything else, with no end in sight. Carbon fiber? I have no idea, although theoretically it should hold up well, but since the whole idea is saving weight, I have a feeling these super-lightweight carbon bikes won't be "timeless" either. One more reason to keep these old steel bikes on the road..............
