Shimano Advances Wireless Di2 Functionality

New Di2 components, app and Bluetooth® wireless Di2 control create on-the-fly customization
Shimano today announced new, advanced wireless functionality for all of its E-Tube Di2 electronic bicycle component systems that allows instantaneous, handheld customization and control of Di2 drivetrains. Working in concert with Shimano’s new wireless-enabled and compatible Di2 components, the new Shimano E-Tube Project iOS and Android compatible app allows riders to customize and infinitely fine-tune their shifting on the tarmac or trail. These new Di2 components and app, working in concert, join Shimano D-Fly Data Management ANT wireless technology that riders have already employed with Di2 component systems.

In 2015, Shimano expanded the capabilities of its E-Tube enabled Di2 components with the Shimano D-Fly Data Management system that transmits Di2 and rider performance data as well as integrating with Shimano Sport Camera footage. Shimano Wireless Units with D-Fly added another dimension to the Di2 experience by wirelessly connecting riders to their Di2 data through compatible cycling computers through a proprietary private ANT wireless protocol.

New wireless capabilities and Di2 components
Shimano E-tube Di2 component systems now allow four points of control for riders and retail service staff, including three wireless connections and one wired connection. Wireless connectivity is the simplest Di2 / rider interface where retail service staff can now perform system checks and firmware updates wirelessly where the wired PC connection is mostly reserved for retailers servicing non-wireless Di2 bikes and OEMs performing initial set up on Di2 and STEPS equipped bikes.
