Ha! I bought the frame off craigslist probably 7 years ago, it is a Cannondale silk road. The reason I grabbed it was I had a bout with nostalgia and my first real mountain bike, a Cannondale Super V 500 from the same era, and I wanted to start road biking. I provided the serial number on the bottom bracket to the guys over at vintage cannondale and they thought it was a crash replacement frame made in 1997, but with a 1999 paint job. I haven't seen the paint scheme on any other bike.

I just added a pic of the built bike at vintage cannondale, but the forum won't let me post an URL yet...

You could find it by googling "vintage cannondale 660" and it should be the first link.

About 3 years ago I finally decided to put some parts on this frame. I put a Shimano 105 (5700) groupset on it, richey pro biomax bar, thomson elite seat post, a selle italia man seat, and FSA wheels.

It is a 62cm frame, and I'm 6'. It is a bit big, as the hoods/bar angle suggests. Regardless, I haven't gotten into road biking and two kids later I'm more interested in finding a bike that is more comfortable for riding around with the family.
