Japanese cycling component manufacturer Shimano will soon be releasing the Shimano XTR M9050 Di2 gear mechanism, a contraption that permits mountain bikers to utilize electrical wiring instead of the usual derailleur cables.

The Shimano XTR M9050 Di2 electronically transmits signals from the gear shifters to the motors located in the front and rear derailleurs. This allows for extremely consistent, quick and smooth gear shifts. The use of electrical cables ensures that a lot of the issues caused by traditional cables -- such as slackening of the steel cables or build-up of contaminants -- no longer pose a problem.

This sytem is capable of shifting both the front and rear derailleurs simultaneously via a single shifter. The contraption coordinates the two derailleurs so that they shift together without getting caught up in each other's chains.
