I've been out of the C&V world for a while, but I just picked this up for my wife to replace her Cannondale. I'm not sure what I have or if it's worth anything... I don't even know what decade it was built.
Here are a few pics in as purchased condition. Mix of Ultegra/600 and Dura Ace parts with 9s drivetrain. Parts are all functional but will likely get swapped out for a mostly alloy Campy 10 group with alloy stem and seatpost.
Columbus SL sticker. Lots of nicks and scratches, but no dent and everything looks straight. Appears to be full chrome underneath the paint.
