This saga (auction) has ended; the bike eventually went for ten times the original asking price. Despite a sale having been agreed (three times), he reneged on the deal - not a great display of integrity. Sadly, I've experienced this kind of thing before.
In one of his last messages, he told me that the bike was mine . . . . . . . but only if I also included a 22" MTB - I think he's rather confused with frame sizes. I don't have a spare MTB, so that was me out of the equation.
It seems faintly ironic, that he mentioned a specific frame size for a MTB, when he couldn't even give the size of the Galibier.
I'd still love to know how he actually acquired the bike.
