Spain experienced hard financial times after WW2. Because Spain had been aligned with Nazi Germany and Fascist Italy plus they were not one of the occupied nations, Spain did not receive the post war benefits of the Marshal Plan which helped much of western Europe recover from the devastation of the war.

The lack of capitol investment resources hindered Spanish industries until the late 1950's when a growing middle class began to develop.

By the late 1960's Zeus was producing sporting bikes and components for the domestic and export market. Zeus components were popular in the UK and Benelux countries because of their competitive pricing against Campagnolo.

Zeus bikes started appearing in the US just before the 1970-1974 Bike Boom. They were never imported in any volume. I think that Zeus Cyclery Corporation of New York City was the primary importer. Most sales were limited to a number of larger US cities.

We sold some Zeus bikes in Albuquerque, NM from about 1973-1977 when the supply dried up. They offer4ed a lot of bang for the buck but were a hard sell because the components were viewed as cheap knock off Campy (far from reality: the headsets and rear axles were superior, the hubs, pedals and seatpost were equal for 1/2 the price).

In the late 1960's Zeus made some entry level sporting models with gas pipe carbon steel frames. Their better models used Reynolds A Quality tubing with butted main tubes which was a medium strength carbon steel, about 2/3rds the strength of Reynolds 531. The top models had Nervex Professional lugs.

About 1970, Zeus introduced their new top end Z-52 Competition model. The frames had pointed Cinelli style lugs with a full slopping Cinelli style fork crowns. The main tubes were butted Reynolds 531 with Durifort forks and stays. They produced some all Durifort models too. Only about a 1/3rd of the lengths of the forks and stays where chrome plated which looked a little weird.

We sold some of the Zeus P66 Cyclocross bikes ~1976-77. That's was when bicycle touring was gaining interest in the US. They had long wheel bases, relaxed angles and cantilever brakes, perfect for a touring bike. The P66 came as a 5 speed with one bar end shifter. We added down tube shifters and a front derailleur. The cranks had chain guards on both sides of the chain ring so they were easy to convert to a triple.

About 1975 Zeus brought out their all Reynolds 531 framed bikes with long point cut out lugs, Zeus 2000 investment cast crown and dropouts.

After that we had very little contact with Zeus.
