Alternatively, through the app, users can swap the functions of the buttons, so, for example, either left hand button can control up shifts and either right hand button can control down shifts in a 1×11 set-up. Mountain bikers also get the option through the app or the software to tell their Di2 buttons to operate their Di2-compatible suspension platforms.
Furthermore, through the app, users can change system settings such as shift speed, multi-shift options and Synchro Shift mapping out on the trail.
What you need to take advantage of these functions:
To connect your groupset to the app or to third party devices you need:
- the new internal battery (BT-DN110) and
- on the road, Shimano’s new EW-WU111 wireless unit
- for mountain bikes the SC-M9051 or SC-MT800 display unit
The new E-TUBE app is available from Shimano’s website here.
