Shimano D-Fly Wireless Unit Di2 E-tube Electric Wire

Shimano Di2 wireless connectivity with D-FLY!
To expand the capabilities of Di2 electronic shifting Shimano introduces a wireless Di2 unit (SM EWW01) equipped with the new Shimano D-Fly Data Management system.
This wireless unit offers Di2 users a new possibility to make their data visible on a cycling computer.

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.SM-EWW01 easily plugs into the E-tube wiring system and seamlessly connects Di2 equipped bikes to a compatible wireless cycle computer. 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. The new Di2 Wireless Unit is powered by the same Di2 battery that powers the Di2 shifting system.

The new PRO SCIO ANT+ bike computer is compatible with Shimano's D-Fly system. The wireless Di2 SM-EWW01 unit is very small, 38 mm long, 25 mm wide and 12.5 mm high and weighs less than 5 grams.
