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 changed the gears—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 electronic commands were sent by wire. The shifting was powered by the movement of the the chain. Impressive.

In 1999, Mavic essentially took the Zap system and made it wireless when it came out with 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 ceased production of Mektronic system in 2002, it was another decade before Campagnolo and Shimano offered electronic shifting.

Complete Mavic Mektronic 9-speed wireless electronic shifting group. Barely used, $1,000.00

Mavic describes the system thus: Another step forward in electronic derailleurs. No more wires; transmission is now by digitally-coded radio waves. Many control points are built into the hand-grips and a multi-function onboard computer attached to the handlebar shows speed, distance covered, elapsed time, sprocket positions, etc.

Cycle historian Frank Berto believes that with the Mektronic system, Mavic was the last purely French company to produce derailleurs.


  • Left and Right Shifter/Brake Levers
  • Rear 9-Speed electronically activated derailleur.
  • Mavic Computer that shows distance, odometer, speedometer, battery life, gear selection and more
  • Housing, cables, zip ties for brakes and front derailleur along with cable ends and ferrules
  • Magnet and sensors for computer and speedometer
  • Mavic Stickers
  • Mavic Mektronic Instruction Manual and Installation guide

Note: The Mektronic system does not include a front derailleur, freewheel nor chain. The front derailleur is not wirelessly controlled. We have period-appropriate Mavic front derailleurs and brake calipers and will happily suggest the right freewheel and chain for you.

Maybe a set of Mavic Kyserium wheels to go along with this set? We have them. Give us a call or shoot us an email.
