I believe it would be a simple matter to debunk these by just sending Craig Calfee an email mentioning the pics posted here. He could easily debunk them.
I agree with Umlungu that the pics do not look real. The resolution is too poor to say definitavely. What I did do is look carefully at details. I noticed the fork Calfee badge color was changed on one pic. It looks to me that the stem of the rear wheel was moved to the front in the second pic. It looks to me that the wheel logo on the rim were removed on the second pic. The seats are identical. The rear brake on the one bike looks like it's attached to a band. I don't believe a real setup would be made like that. We all know how brakes are mounted. The band is the same as the derailleur band, I believe.
Why would someone post Calfee bikes like that on the Serotta forum in the first place? And two of them? No background about the bikes, either. If they were real I would assume the poster would have talked about how they came about, where they were and when they were made.
