Zeus Cyclery Corp. was an importer of European cycles and components based in New York City, USA. It was possibly founded in around 1975.
I have a feeling that Zeus Cyclery Corp. disappeared some time in the late 1980s. I might guess that it was one of the many victims of that period's tectonic shift from road bikes to mountain bikes. In the bike shop that I worked in, about 80% of the bikes that we sold in 1980 had drop handlebars. By 1995 the proprtion was less than 10%.
But then, whatever goes around comes around.
