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.

Install tips and tricks

Total :


Physically, this is super easy to install (providing you manage to find the correct length of cable in stock somewhere). Electronically, however, there are some tricks. Firstly, you'll most likely need to upgrade all your di2 components to the same firmware version using the USB PC interface. Once you've done that, ignore the Shimano pairing instructions. Once you get your computer in search mode (the Garmin 510 has a separate search for di2, you have to click on the di2 icon to enable it first). Then you'll need to activate both dérailleurs before the D-Fly will be detected. I spent ages unplugging and plugging the battery, like the Shimano instructions suggested, and flicking the front dérailleur. It wasn't until I happened to move the rear shifter that suddenly it was detected! Now it's all working great!

Di2 D-fly ANT + unit

Total :


An excellent piece of kit! When used in conjunction with the Garmin Edge 520, the Di2 D-fly + ANT allows recording of gear changes and battery status through out the ride. I find the gear changing information the most useful (I chase cadence) as it allows me to concentrate on riding instead of constantly looking down to see which gear I'm in. The unit is small and unobtrusive and easy to install. One downside- Shimano do not include a cable, this has to be purchased seperately. Thumbs up!
