What is now Mavic was started in the late 19th century as a maker of bicycle components. But it was in 1934 that Mavic hit its stride when they began making aluminum bicycle rims. The Tour de France initially forbade their use, Tour boss Henri Desgrange feeling that they were unsafe compared to wooden rims. Antonin Magne won his second Tour in 1934 using Mavic rims that were painted to look like ones of wood.

Mavic introduced their own component groupset in 1979. The rear derailleurs were beautifully well-made and had an interesting difference. All the derailleur pivot pins were held in place with removable circlips. The derailleurs could be completely disassembled, cleaned and rebuilt. Broken or worn parts, even of the parallelogram, could be replaced.

But Mavic was looking far ahead. In 1992 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 sent the information to the electromagnets in the derailleur, all in real time. The shifting was powered by the movement of the the chain. Impressive.

Then in 1992 Mavic essentially took the Zap system and made it wireless. Through the Mektronic system, transmission of shifting commands were now sent by digitally-coded radio waves. Many control points were built into the hand-grips and a multi-function onboard computer attached to the handlebar showed speed, distance covered, elapsed time, sprocket positions, etc.

While Mavic eventually ceased production of Mektronic system, it was another decade before Campangolo and Shimano offered electronic shifting.
