I have a 1993 2.8 Series R800 in all original spec excepting the shifters which I changed to Shimano Sora after the original 105s wore out. Unfortunately, I think it's a 56cm but would have to check to be sure. Colour is Deep Indigo. Full spec is here: http://vintagecannondale.com/year/1993/1993.pdf
It's been described by the staff in my local bike shop as 'mint for it's age'. (There are a few minor scrapes to the paint finish but no dents to the frame).
I have recently upgraded and have been wondering what to do with this bike and whether its value would be maximised by breaking up or finding a buyer for the complete bike. If it's of interest I'm open to offers.
I have cannondale saeco red one frameset with a time fork If I'm correct a black fork
I think it's a 56c/c seattube
