Shimano launch Di2 Wireless D-Fly

Shimano has launched it’s first wireless Di2 computer to tell users real time gear and ride data.

A retro fit wireless unit, the catchily named SM-EWW01, plugs into the existing E-tubing and via a ‘private’ ANT+ wireless connection, uses the D-Fly data management system to allow riders to monitor Di2 gear position, battery life, along with a few other ride data functions.

The £69.99 unit will be compatible at first with the £99.99 PRO SCIO ANT+ and £119.99 SCIO Alit ANT+ , new 80gram computers from Shimano’s house brand PRO compatible with other ANT+ sensors, such as Power, heart rate, cadence etc. Shimano state future compatibility is expected with other ANT+ computer manufacturers due to launch in the coming weeks, as long as they have asked Shimano for permission to use the ANT+ code.

Before you get excited about remote gear shifting – this is a one-way communication street, so only data telling you what’s going on will be transferred. But it’s definitely a step in the right direction towards wire free electronic shifting.

According to Shimano the wireless unit, SM-EWW01, will weigh less than a 5grams and isn’t far off the size of the existing control box, while the PRO SCIO ANT+ computer weighs 80grams. Available in the UK from March onwards.
