'92 22" Cannondale M2000, '92 Cannondale R1000 Tandem, another modern Canndondale tandem, Two Holy Grail '86 Cannondale ST800s 27" (68.5cm) Touring bike w/Superbe Pro components and Phil Wood hubs. A bunch of other 27" ST frames & bikes.
Is that a 1" headset? That 'dale might be older than '92 then. I think in '92 Cannondale was using 1 1/4" on some bikes.
Its a good bike with a light strong aluminum frame. As for value, its worth whatever someone would pay for it. I'd just donate it to a Goodwill/ARC. I doubt you'd get $50 for it.
Appears 90's model -- Cannondale did use 1" steerers on some models into the mid-90s. It's a good frame, very light. Group is probably junk, ask what model (e.g. SM-xxx or whatver). Looks like alum fork so it'll have a STIFF ride. Would make a good urban bike. And it is a Cannondale. I'd pay $100 for it, no prob. 200$ is high but not crazy if great condition.
It looks to be a 1990's with the decal on the top tube and rapidfire shifters. Which is good as they came w/ Crmo forks in varing degrees of quality depending on the line. Components either SunTour XCM or Shimano Deore again depending on level.
