That frame is absolutely identical to the Trek 9700 OCLV i had a few years ago, even down to the seat collar. Mine was a '97 model I think. Nice looking frame i always thought and light as a feather.
EDIT: oops just looked at how old this thread is! AND you've already sold on the bike!... was just doing a seach for 'supercaliber' and got this thread... sorry to dredge up old history!
------
I can't remember where I got this scan from - may even have been from this site... from the '95 catalogue.
A mate of mind had one of these and loved it 'til it got nicked.
very very nice frame... if a bit fragile.
Nothing wrong with Treks IMO.
Now if anyone can help me out with a catalogue scan of the Supercaliber from 1991 I'll be happy!
