The seller may well be a list member, all I know is it ain't mine (and with a 52cm frame, it never could be). And the asking price is $3200, which would rule it out for me even in an appropriate size.

Without casting too much doubt, this seller is due some pointed queries. One obvious one: where are we supposed to view the other images mentioned in the description?
