This is the European patent application for the design that became the MAVIC ZMS 800. It also relates to French Patent # 2,687,977 and European Patent # 0 528 425 B1.
This European patent application, lodged a year after the French original, shows:
- The inventors, Jean-Pierre Corbier Lacombe and Jean-Pierre Mercat, were based in Chavanod and Can-Gevrier, both of which are suburbs of Annecy, France (see scan 1)
- The applicant was B. G. Innovation (S.A.R.L.) based in Annecy - not MAVIC S.A. based in Saint-Trivier-sur-Moignans, 130 km away (also see scan 1). However Chavanod, near Annecy, is also the location of the factory in which MAVIC had manufactured bottom brackets, derailleurs and other components, since 1978.
- Unlike the French patent, the drawings include images of the slanted sliding rod mechanism eventually used in the MAVIC ZMS 800. This was designed to maintain a fairly constant chain gap (see scan 22 and scan 23).
