O.K.
The thread is getting long, but, as a Zeus aficionado, I must chime in.
I don't quite understand how the idea of Zeus copying Campagnolo, let alone "using copies of Campy molds" came about. Ridiculous. Admittedly, the Zeus Criterium rear derailleur looks a lot like an old Record Campagnolo. However, a side by side comparison of hubs, brake calipers, brake levers, cranksets, etc. will show that they are not even close! As mentioned, Zeus made gorgeous center pull brakes for the early 2000 groups. The Zeus 2000 brake levers had quick releases built into the levers. Campy made nothing of the sort. Zeus 2001 side pull calipers are beautifully finished, and have basically nothing in common with Campagnolo. Cranksets are a completely different bolt center diameter, and to my eye, are very nicely finished. Zeus was an innovater in the use of Titanium. As someone mentioned, Zeus 2000 had pedal cages that were constructed of Titanium, not just the axles. Zeus 2000 groups used titinium bottom brackets, titanium pedals, and titanium material in t
he rear derailleurs. Also, as mentioned, Zeus was an innovator in the manufacture of alloy freewheels as early as 1974:
