OP bike sure looks like a '78 though that may depend on market of country. I acquired a US market 1978 Moto'bacon' barn find that transformed into a tribute Ocana / BiC. Excellent rider and absolute super fun budget project. Positively id having Vitus 888 tubing. Good enough for a smaller size frame of which I could just fit with a longer post.

Retained the stock handlebar, Motobecane marked (Weinmann 500) brakes, crank (Sugino). Replaced everything else with leftover Campy N. Record, hubs, pedals too. B17 narrow saddle. 700c tubulars. The project was embarrassing cheap. Super fun and attention grabber. I wouldn't mind doing another and exact build.

Originally marketed for junior class racer with regulation gearing.
