According to First Flight Bikes,
http://www.firstflightbikes.com/schwinn_specs.htm
the Paramountain was made in 1987 only. For 1988, it was replaced by the Project KOM-10 Team Issue, which was made in Greenville MI. My KOM-10 uses the original Schwinn serial numbering system, such that F8xxxxx denotes June 1988 frame fabrication.
My KOM-10 has a U-brake under the chainstays and a SunTour RollerCam in front.
