We sold some of these Zeus P66 Cyclocross bikes in the mid 1970s. Zeus was big in CX back then and a lot of their bikes were rebadged to race under other colors.
The frames were Durifort and the brakes were probably MAFAC cantilevers with Zeus levers??? They were 5 speeds with a singe barcon on the right side. The angles were relaxed and they had long wheel bases.
We converted them to 10 speeds and sold them as touring bikes which they were ideally suited for.
Here's some pictures of a 1975 Gios CX bike:
This is a staged photo for a Gios ad. The bike Roger De Vlaeminck is carrying is a standard Gios road bike.
Here's shots of De Vlaeminck on real Gios CX bikes.

We started riding off road on road bikes in 1976. Used CX sewups whenever possible, otherwise 700x35c "Ville" urban bike clinchers that we got from France.
