I'm leaning towards a 1985 Schwinn Peloton.
Edit: It's definitely Tange built with a Columbus steerer which would be correct for a Peloton. The date code is October 1984 which would be a 1985 model and the Peloton was spec'd with Superbe Pro that year, which would explain the dropouts (the 1985 Schwinn catalogue states SunTour dropouts but not the model). The colour is correct, as is the blade end treatment, dropout chroming, fork crown style and absence of crown embossing. The only thing I'm not sure about is the heart cutout in the blade reinforcing tang.
