After pairing a Shimano Di2 to your Karoo, you will be able to see your current gear data on the screen while also allowing you to control the Karoo without taking your hands off the shifters.
You can pair the Di2 to your Karoo as you would pair any other sensor.(However, try to pair other sensors after you pair your Di2 and not at the same time as this will take precedence). See: Adding ANT+ / BLE sensors
How to control your Karoo via Di2 Hood Buttons during a ride:
- New Data fields added under "Shifting":
- Graphical Data Field: Current Gears Selected
- Numeric Data Fields: Battery Status, Electronic Shifting Mode, Front Gear, Rear Gear, Number of Shifts.
- Settings Available:
- Riders are now able to change the Di2 shift mode between Manual, S1, and S2 modes in the detail page for the sensor.
