The early 70's Grand Jubile was I think a somewhat underrated bike. In '74 and '75 it was equipped with a Stonglight 49 crankset and Huret Jubilee derailleurs/shifters, Pivo bar and stem, Weinmann centerpulls, Normandy hubs with Weinmann clinchers...certainly not top of the line componentry. Nevertheless, it is a very quick, agile bike and I find it compares nicely with my Le Champion and PX-10. I've substituted Normandy Competition hubs with Superchampion rims and sewups.
