Shimano’s Di2 becomes wireless: D-Fly

Traian Goga February 3, 2014 Industry, News No Comments

What’s a modern-day electronical system if it isn’t wireless? Shimano was thinking the same thing, and announced yesterday the launch of the long speculated-on and expected wireless upgrade for its Di2 electronical gear shifting system.

The Di2 wireless unit is a compact wireless data transmitter compatible with Dura-Ace 9070, Ultegra 6870 Di2 and Ultegra 6770 E-tube road shifting systems. Coded SM-EWW01, it can be pluged into the E-tube wiring system and connects Di2 equipped bikes to the current sole compatible wireless cycle computer, the PRO SCIO ANT+. However, future compatible units will be offered by MIO, which are planned for the 1st quarter of 2014.

Shimano D-Fly transmits data through a proprietary private ANT wireless protocol and allows riders to monitor Di2 gear position, battery life, as well as some other common rider data functions, basicly being a sort of updated Flight-Deck.

The new Di2 Wireless Unit is powered by the same Di2 battery that powers the Di2 shifting system, and it also features a piece of software, the D-Fly Data Management system. The SM-EWW01 maintains a size of 38mm in length, 25mm in width, and 12.5mm in height, weighing less than 5 grams.
