Further expanding the capabilities of its E-tube wiring and electronics found in its latest Di2 electronic road bicycle shifting systems, Shimano today introduced the Di2 Wireless Unit (SM-EWW01)featuring the new Shimano D-Fly Data Management system. This new wireless component adds another dimension to the Di2 experience by wirelessly connecting riders to their Di2 data through a cycling computer.
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.
Upon its introduction, SM-EWW01 will be compatible with the PRO SCIO ANT+ cycling computer, a new 2014 introduction in the PRO line. Future compatibility with others cycling computers are planned for the 1st quarter of 2014.
Di2 Wireless Unit SM-EWW01 maintains a svelte size at only 38mm long, 25mm wide, 12.5mm in height, and weighs less than 5 grams.

Works nicely, finally setup to garmin edge 1000.
If you have di2, then this really is the icing on the cake. Feeds back to your compatible device (Edge 1000 for me). Small and easily installed. Mine is neatly tucked into the seat tube. Oh, don't forget the necessary (but expensive) connection wire - it's not included.
Really good works really well on my bike. Let's you know a bit more about the di2 system on your bike. Excellent
Clever add-on for di2 allows you to monitor battery life and gear ratio's - I find this handy on the trainer as I can be more consistent with previous workouts. Doesn't tell you on official info but I fitted mine in the seat post inline with battery so no sign it is there and works fine. Worth noting you will need to buy an additional wire to connect it as doesn't come with one.
