1992 : Electronics components

Mavic developed an electrically-controlled derailleur that was tried out by the Once and RMO teams in the Tour de France. A new French revolution!

The following year Mavic launched the ZMS (Zap Mavic System), the first micro-processor driven rear derailleur. Two strategically-placed buttons on the handlebar to change gear-up or down-then with a feather-light touch the microprocessor in the handlebar sends the information to the electromagnets in the derailleur, all in real time.
