The Cosmos, By Zeus

Last year, "The Retrogrouch" wrote an excellent article about the Basque component (and bicycle) maker Zeus, which was based in Spain.  They began manufacturing in 1926--a decade before Campagnolo--and seem to have continued until the late 1980s, or possibly the early 1990s.

Zeus is interesting for a number of reasons. One is they made almost everything on their bicycles:  Apparently, only the tires, tubes and spokes were not made by them, or one of their subsidiaries.  Perhaps only Raleigh, at least before the Bike Boom and on their three-speed models, manufactured as much as, or more of, their bikes than Zeus did. ("Schwinn-Approved" components were made by other manufacturers, e.g., Weinmann and Dia-Compe brakes, and Huret and Shimano derailleurs.)

Another reason why Zeus is worth looking at is that, while they developed a reputation for copying the designs of other manufacturers, they added their own touches and enhancements.  For example, their centerpull brakes were patterned after Weinmanns but were made with tighter clearances, tire guides (like the ones found on high-end sidepull brakes of the time), recessed allen bolts in the pivots--and a nicer finish.  And other components, such as the cranksets and derailleurs, used their Campagnolo counterparts as their starting points but departed in some details that didn't change their function but gave them character--and, often, made them lighter.  And perhaps no components more conspicuously exemplified the "drillium" trend of the 1970s than the "2000" line of components.

The funny thing is that the more Zeus came up with their own designs --they accumulated over 100 patents in their history-- the more they were criticized as "Campy copies".  Or so it seemed.

Even more ironically, those who made such criticisms probably never saw the Zeus part that was, perhaps, the nearest clone of the Campagnolo part that inspired it.  Actually, most of those critics didn't even realize the part in question--and others of the "gruppo" of which it was a part-- were made by Zeus because they were sold under the name "Alfa".

(The Spanish language doesn't have "ph" and "gh" diagraphs, as we have in English.  That is why it's spelled "Alfa", not "Alpha".)

Now tell me this "Alfa" derailleur doesn't look like the first version of the Campagnolo Valentino Extra:

Zeus Alfa

Campagnolo Valentino extra, first version

About the only visible differences between the two are the toothed pulleys on the Alfa, and the finish on the pivot bolts and adjustment screws of each one (black on the Alfa, chrome on the Valentino).  I never tried the Alfa, but I imagine that it doesn't shift much, if at all, differently from the Valentino--which was unexceptional, even for its time.

At the end of my first paragraph, I said that Zeus seemed to have continued until the late '80's or early '90's.  I could not find any information on when they succumbed (If Nietzsche were Greek, would he have declared that Zeus is dead?), but I had long thought that it was in the early or mid-80s, not long after they produced the 2000 series, their most renowned components.  Yet, while trolling eBay, I came across this:

European derailleur makers began to copy Shimano and SunTour designs during the early and mid-1980s, when those Japanese companies' patents started to expire.  Now, for all I know, Zeus may have made the "Cosmos" derailleur before that, as Spain was notorious for its lax patent laws.  Then again, it may have been made for them by someone else, although Zeus wasn't known for contracting other manufacturers.

Whatever the case, I never saw a "Cosmos" derailleur before.  Perhaps they were not produced for very long, or were not exported to the US.  If nothing else, it--ironically enough--belies the stereotype of Zeus as a "Campy copier".
