Shimano has added a new component to unlock wireless capability within existing Di2 groupsets – but don't get too excited, this isn't an upgrade to wireless shifting!

Instead, it's a way for Di2 owners to display gear position and battery life data from their transmission on a compatible cycle computer.

The SM-EWW01 plugs into the E-tube wiring system of current Di2 groupsets, where it then transmits gear position and battery life data wirelessly to a compatible cycle computer. It's what Shimano is calling the D-Fly Data Management system.

The component is powered via the same Di2 battery that powers the shifting system. It's compatible with Shimano's Dura-Ace 9070, Ultegra 6870 and Ultegra 6770 Di2 groupsets. Retailing at £69.99, the unit weighs just 5g and is fairly svelte – only 38mm long, 25mm wide and 12.5mm tall.

Currently the SM-EWW01 is only compatible with the PRO SCIO ANT+, a new £99.99 computer from PRO's 2014 product line. Shimano says it's currently working with MIO and other companies to increase compatibility by later this year.
