Identify Cannondale frame size

There's a Cannondale frame for sale on Ebay ( CANNONDALE FRAME AND FORK ) but the owner doesn't know what size it is. I asked the owner to provide the serial number ( 66011A80369 ) but the serial number doesn't match any of the formats that I found on vintagecannondale.com. Anyone have a idea on determining the actual frame size? He thinks it's a 56 or 58.

I'd say it's a 60cm and that the owner may have mis-read some of the digits after the first three or five of them. Note that it's probably 58cm or so CTC.

Color scheme and Tange unicrown fork mark it as an '89 SR400 3.0 Criterium frame, originally came with RX100 7 speed & DT shifters.

Cannondale frames look smaller than equivalent seat tube length steel frames due to the diameter of the down tubes. I'd say 58-60cm, looks more like a craigslist sale than an ebay sale too.

I'm pretty sure the S/N was misread. 6 60 1188 0369 is more likely:
6=126 mm drop out spacing
60=size
1188=manufacture date
0369=sequence number

The frame set was originally a SR600 w/aluminum fork.

Thanks, you're right about the Craigslist. I guess I had Ebay on my brain.
