Bonafide players in the world of cycling for many years. The company succumbed to market forces in the early 1980's but produced,  especially toward the end of their business life, some of the most exotic components of the era.

      "Zeus was founded by Luis Arregui in Eibar, Spain in 1926. That makes the company about 10 years older than Campagnolo. Arregui held over 105 patents, and the great catalog was published in commemoration of him after his death. Luis Ocana was able to win the Tour de France for Zeus against the practically unbeatable Eddy Merckx in 1971. Zeus was the only company in modern times to build a complete professional bicycle (frame and components)."   Richard Hallett
