John Landis said, referring to Zeus "Campy eventually sued the out of existence". I might be mistaken but I was under the impression that they were still in business, supplying carbon fiber rear subassemblies for frames as well as other parts.
I have memories of looking at Zeus parts and bicycles at Kissena Cycle Shop in Flushing Queens on the service road of the Long Island Expressway. I think Al Toefield, who owned the store, as well as being a NYC police officer was the US importer for Zeus.
