Ya gotta wonder about some ebay sellers...
This guy has been re-listing this 1984 Trek 970 frame and fork for at least a couple of months, starting bid at $899 (a bit optimistic, if you ask me). Surprise, surprise, hasn't sold yet. I even contacted him about a month ago to tell him exactly what he had (year and size) based on the serial number, but he hasn't updated the ad at all, based on that info.
He also lists the vintage-trek.com website as "trekvintage.com," which of course leads nowhere.
