Electronic transmission by bike
Bicycle with a shift on bluetooth? Soon they will. In the meantime, an overview of working solutions for expanding horizons.
Electronic transmissions are wired or wireless. The wired system assumes the presence of wires leading from the knobs to the control module and from the power module to the switches. Signals are transmitted through these wires to where the switch should move. It is this type of transmission that has been mass-produced recently by Shimano.
Wireless transmission was produced in the late 90s by the company Mavic under the name Mektronic. This type of transmission does not require the presence of wires connecting the components of the system: control signals are transmitted via digital coded radio signals, and the power elements (batteries) are located directly in the switch construction. Such a transmission, as you might guess, was distinguished by increased complexity. Maybe because of this, she didn’t really get accustomed, moreover, after the story with this transmission, Mavik stopped producing transmission components in general.
The harsh reality has made its own adjustments to the designs of designers. The main reason is the lack of reliability and complexity of maintenance and repair. Although this did not prevent at one time the leading bicycle manufacturers to produce bicycles equipped with this system. Take, at least Cannondale Stallion 2000, a photo of which is at the beginning of the article.

Who else does this? Of course, Shimano and Campagnolo. The first electronic transmission refers to the lineup in 2009 and has an index of Dura-Ace 7970 Di2. Kampa has not yet seen the serial version of these components even next year, although the working Electronic Record models have been demonstrated since 2003, and rumor has it that even tested on the Tour de France, but it was not possible to find who tested and with what result.
An attentive reader will ask: "What the hell is this for?" I answer - the weight of the switching wires, their friction in shirts, linear expansion (cable lengthening) with a temperature difference of +30 to 0, which happens in mountain races, switching fuzziness - all this can theoretically be overcome by the electronic switching system.
