BB Pivot looks offset, is that right? That, and the profiled downtube suggests at least some thought has gone into the design! Any news on serial number? I assume it's not a Specialized or an Apple iBike then! =P
The closest I came to looking at the welding (not Cannondale) and the shock travel, but knowing it must be at least mid-00's given the IS disc mount was an Apollo.. The later FS26 has a similar front triangle design but with different shock/placement. That's not all bad news if it is one, they do 'make' some decent bikes even now!
