Possibly, but they are 15 year old frames (and equipment by the looks of things - Square Taper K-Force anyone?), so unlikely they were there to be used by pros.
A curiosity no doubt though. Wonder who's shed they've been in, and how much dust needed to be removed.
Heh. That photo is rather old, non? Looks like a CAAD7 frame, from like 2003.
When they might have been bleeding edge.
