This is the Shimano SM-EWW01 D-Fly Wireless Di2 Unit. Further expanding the capabilities of its E-tube wiring and electronics found in its latest Di2 electronic road bicycle shifting systems, Shimano introduced the Di2 Wireless Unit (SM-EWW01) featuring the Shimano D-Fly Data Management system. This 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.

Needed to install: IEWSD50L15 or any length e-tube wire.  150mm is shortest available and is recommended.
