Bandera, I should have remembered earlier that Cannondale did make smaller framed bikes in 650C (my mind remembered them as 650B) and this may offer what you're searching for. A quick and dirty search showed that tires and rims are available, but perhaps not at the upper level you're seeking.
A nice link with some generic info:
650 versus 700c wheels - Are small wheels slow? 650 vs. 700c

PS With so much development of the tubular and clincher 700C bicycle rim, who knows if 650B will progress from the mountain bikers and those wishing to use larger tires on their 700C road frames.
