French Patent 2,506,251 - MAVIC main image

This patent looks as though it covers a proposed development of MAVIC's signature 800/850 design. It includes a couple of interesting features:

  • The parallelogram plates have a distinctive 'V' shape that is very reminiscent of designs that Shimano used on its ATB derailleurs many decades later.
  • The b-pivot has an offset mounting bolt which, this time, is remiscent of a Gian Robert derailleur.

If this design had ever been manufactured, it would have been a natty looking piece of kit.
