Archer Components is already offering what others are still working on or are about to launch: Electronic shifting that transmits shifting commands wirelessly from the shift lever to the rear derailleur. The Archer "D1x" system solves this problem with a servo motor that is attached to the frame near the rear derailleur. This motor then pragmatically pulls on a shift cable to change gears with the activated rear derailleur. This gear change servo is operated by means of a shift lever, which enables downshifting and upshifting with two buttons and can be attached to the handlebars with a Sram clamp.

The switch and servo are powered by AA and AAA batteries; once these are fully charged, around 1000 gear changes should be possible, which is enough for around 30 to 50 hours of operation. The system works with single-chainring systems from Shimano and Sram, and an app makes it possible to adjust the shifting. This is also where the "D1x" reveals its potential, as it can be adapted to all rear derailleurs and cassettes; systems with up to 20 (potential) gears can be adjusted.

And for whom does such a wireless system make sense? It is conceivable for mountain bikers who simply fancy something new and for whom shifting with a cable or Di2 has long been old hat. This wireless transmission of shifting commands could also be a nice problem solver: On bikes with cables routed in the frame, changing the outer casing or the shift cable can turn into a veritable orgy of screwing and fiddling. In this case, the Archer "D1x" system can save a lot of time and nerves. Speaking of saving: At 235 grams, the "D1x" is also on the economical side when it comes to weight.

If you want to buy the "D1x" right now, you will need to perform a few logistical feats: The California-based manufacturer charges 389 US dollars for the "D1x", but currently only delivers to the USA, Canada and Mexico.
