Wow, that is surprising on the $655 deal, given the mishmash of parts on that thing. The one at $405 has some Record and Super Record at least. The other one currently at $81 also has some slightly more upscale parts, but it's still a mongrel.
I've got an '85 560 with full Suntour Cyclone I'll sell you for half the price, and the Cyclone will far outperform that Campy stuff! Problem is, it's a lot taller than that $655 660.
