Shimano first unveiled its Di2 (Digital Integrated Intelligence) trekking components back in 2001. However, it wasn’t until the 2009 product year that Shimano integrated electronic shifting into its dedicated road bike lineup, marking a significant milestone in cycling technology. Today, Shimano continues to expand its offerings, providing Di2 electronic components down to the third-tier 105 model, with expectations of more advancements on the horizon.
Pics from Mavic
During the 1990s, the landscape of cycling groupsets looked remarkably different from what it is today. In a surprising turn of events, France’s Mavic, a brand primarily known for its high-quality wheels, emerged as a pioneer in electronic shifting technology. In 1992, Mavic innovated an electrically controlled derailleur, which was tested in the prestigious Tour de France by the Once and RMO teams.
The subsequent year saw the launch of Mavic’s ZMS – Zap Mavic System, which was revolutionary as the first microprocessor-driven rear derailleur (the front derailleur, however, still relied on traditional cable mechanics). Although this system was a precursor to modern electronic shifting, it allowed riders to change gears using two buttons situated on the handlebar. A microprocessor located in the handlebars transmitted the command to a solenoid in the rear derailleur, which, upon activation, released a ratcheting bar to facilitate gear changes. Notably, this bar would only move while the rider was pedaling, adding a layer of complexity to the design.
One of the key advantages of electronic shifting lies in its flexibility to install multiple switches performing the same function. For example, Shimano has created sprint and climbing shifters, while SRAM offers customizable Blips that can be positioned in various locations for effortless gear changes, particularly advantageous in time trials where access to traditional shifters may be limited.
Chris Boardman famously utilized Mavic’s electronic shifting system to secure the yellow jersey by winning the prologues (short time trials) of the Tour de France in both 1994 and 1997 while riding for the GAN team. Ultimately, Mavic recognized that the Zap system fell short of the industry’s standards, leading to a suspension of production. Nonetheless, this initial foray into electronic components paved the way for continued research and development in derailleur technology.
In 1999, Mavic advanced its electronic shifting efforts with the introduction of the Mektronic system, which marked a departure from traditional wiring by employing digitally-coded radio waves to transmit signals between components. This cutting-edge system featured controls integrated into the hand grips, along with a multifunction onboard computer mounted on the handlebar that displayed various metrics like speed, distance, elapsed time, and the current gear sprocket.
While the control power was sourced from a battery, the shifting mechanism drew energy from the chain itself. Despite gaining a following among enthusiasts, the Mektronic system ultimately succumbed to reliability issues, with shifts often being unacceptably slow, leading to its discontinuation. Today, Mavic no longer manufactures shifters or derailleurs, but its pioneering efforts in wireless electronic shifting during the last century stand as a significant historical milestone that inspired competitors to advance the technology further.
