Use electronic drivetrains with ELEMNT ACE, BOLT 3, or ROAM 3

Third generation ELEMNT GPS bike computers (ELEMNT ACE, BOLT 3, and ROAM 3) support some ELEMNT button control, current gear and battery level data in sensor details and data fields, and some historical gear selection data in activity history when paired with with Shimano Di2 , SRAM eTap/AXS, Campagnolo EPS, and FSA K-Force WE drivetrains. Some sub-features will vary by computer or electronic drivetrain.

Features

ELEMNT computer button control

Shimano Di2 and some SRAM AXS drivetrains allow for pre-mapped button control of ELEMNT computers.  The button mappings are hard-coded and not customizable.

Shimano Di2 -  ELEMNT computer control 

Shimano Di2 drivetrains with additional buttons located on top of the hoods and wireless connectivity integrate with all ELEMNT computers to allow most remote button controls from the hoods. 

  • Quick press left hood button to simulate pressing the left front computer button.
  • Quick press right hood button to simulate pressing the right front computer button.
  • Long press left hood button to simulate the up (left)  right side computer button.
  • Long press right hood button to simulate the  down (right) right side computer button.

 

Setup

ELEMNT computers are designed to work with the default settings for the shifter hood buttons.  

  1. Ensure that the shifter hood buttons do not already have a function designated to them in the E-Tube Project app, leaving them open. 
  2. The left hood button should be configured for ch. 1 and the right hood button should be configured to ch. 2.

SRAM AXS -  ELEMNT computer control 

SRAM Red shifters (2024+) with additional 'Bonus' buttons located on top of the hoods and/or AXS Wireless blips integrate with ELEMNT computers to allow for button control from the bars.

Red shifter Bonus buttons can be mapped to simulate all button controls, except the left side Power / Menu button..

A pair of AXS Wireless Blips can be mapped to simulate ELEMNT front button controls.

RED AXS Bonus Buttons

  • Quick press left hood Bonus button to simulate pressing the left front computer button.
  • Quick press right hood Bonus button to simulate pressing the right front computer button.
  • Quick press both hood Bonus buttons simultaneously to simulate pressing the middle front computer button
  • Long press left hood Bonus button to simulate the up (left)  right side computer button.
  • Long press right hood Bonus button to simulate the  down (right) right side computer button

Setup

In the SRAM AXS app, map:

  • Left Bonus button short/long press to ANT+ Function 1.
  • Right Bonus button short/long press to ANT+ Function 2.
  • Simultaneous short press to ANT+ Function 3

For more details on this process, see SRAM's article on configuring AXS buttons.

AXS Wireless Blips

  • Quick press left Blip to simulate pressing the left front computer button.
  • Quick press right Blip to simulate pressing the right front computer button.
  • Quick press both Blips simultaneously to simulate pressing the middle front computer button

Setup

In the SRAM AXS app, map:

  • Left Blip Short Press to ANT+ Function 1.
  • Right Blip Short Press to ANT+ Function 2.
  • Simultaneous Short Press to ANT+ Function 3.

For more details on this process, see SRAM's article on configuring AXS buttons.

View current gear and battery levels in sensor details

Shimano Di2 SRAM eTap + other  

The current gear selection and battery status of the electronic drivetrain will be visible on the drivetrain's sensor detail page in the ELEMNT computer's sensor menu.  Specifically, the following will be visible on the sensor details page:

  • Numerical indication of current front and rear gear position
  • Shifter battery levels (if shifters are powered by individual batteries)
  • Derailleur battery level(s)
    • Listed as a percentage if powered by main Shimano Di2 battery
    • Presented separately with battery icons if powered by individual batteries

Setup

  1. Once the electronic drivetrain is paired, navigate to the Device Settings page (tap left side button)
  2. Navigate to the My Sensors page (tap the bottom right button)
  3. Select the Shimano Di2 or Gear Selection line item using the touchscreen or right side buttons to scroll and middle button to select Select.

    • Current Gear ("Gear Num")

View historical gear selection in ride history

Gear selection data for individual rides are visible in the activity details of rides found in the History tab. Specifically the following details are available for review:

  • Favorite gear combination (dependent upon gear configuration in the WAHOO app)
  • Time spent in each gear

In order to correctly model your bike's gearing, you can set the tooth counts of both chainrings and cassette cogs.

Setup

To configure the drivetrain's tooth counts, once it has been paired to your ELEMNT computer

  1. Open the Wahoo app.
  2. Navigate to the Devices tab.
  3. Select the ELEMNT computer.
  4. Select the drivetrain from under the Paired sensors menu. 
  5. Use the drop down menus to configure the tooth counts of chainrings and select a pre-configured cassette or Custom to manually set the tooth count for each cassette cog.

You can modify the tooth counts of both chainrings and cassette cogs, as well as cassette cog count. Your drivetrain's chainring count, however, will be mirrored from your drivetrain and cannot be overwritten.  In the case that you have manually converted a 2x crankset into a 1x setup, set the default chainring as 

Also, please note that configuration of your gears in the Wahoo app has no impact on your drivetrain's actually configuration. To modify your drivetrain's configuration, use the manufacturer's proprietary app.

Troubleshooting

ELEMNT computer control with Di2

Most issues are due to button customization in the Shimano E-Tube Project app.  ELEMNT computers are designed to work with the default settings.

  1. Ensure that the shifter hood buttons do not already have a function designated to them in the E-Tube Project app, leaving them open. 
  2. Reset Di2 settings to default configuration in the app to restore functionality.  The left hood button should be configured for ch. 1 and the right hood button should be configured to ch. 2.

ELEMNT computer control with SRAM AXS

  1. The AXS rear derailleur must be paired to the ELEMNT computer as a Gear Selection sensor.
  2. In the SRAM AXS app, the buttons should be mapped as follows:
    1. Left Blip Short/Long Press to ANT+ Function 1.
    2. Right Blip Short/Press Press to ANT+ Function 2.
    3. Simultaneous Short Press to ANT+ Function 3
  3. Forget and re-pair the rear derailleur as a sensor.

Sensor details battery level or data-field battery or gear selection data

  1. Ensure that your computer is up to date on current firmware.
  2. Forget/re-pair the drivetrain as a sensor.

Gear selection/configuration data

In order to ensure future ride summaries reflect the correct gear configurations,

  1. Ensure your computer firmware and WAHOO app are up to date.
  2. Follow the steps above to confirm/change the gear configuration of your SRAM eTap/AXS drivetrain.  
  3. Forget/re-pair the rear derailleur as a sensor.
