Connectivity with bike computers

It is possible to pair the Classified thru axle with your bike computer. This will allow you to check your thru axle's battery level and to see the gear ratio you are riding in. In this article we explain how to pair, or connect, your Classified thru axle to your bike computer.


1. Garmin

1.1 Pairing your Garmin with the Classified thru axle

Pairing is possible with the following devices: Garmin EDGE 1000, 1030, 1040, 520, 520 PLUS, 530, 540, 820, 820 PLUS, 830, 840

  1. Make sure your Classified thru axle and your Garmin bike computer are within 3 meters (10 feet) of eachother. To avoid connecting with the wrong sensors, make sure to stay away at least 3 meters (10 feet) from other rider's sensors.
  2. Shake your thru axle or move your bike to wake up the sensor.
  3. Add the thru axle on your Garmin device by selecting menu > sensors > add sensor.
  4. Select 'shifting'.
  5. Tick the box next to the Classified sensor.
  6. When the shifting sensor (the Classified Thru axle) is found, you will be asked to: 'add custom data screen to support new sensors?'. Tick the box to add this data field to your screen to display gear info. You can also add this extra data field to your screen later on.
  7. The sensor status should be connected.

1.2 Setting up chainring sizes

  1. On your Garmin computer, go to menu > sensors
  2. Select your shifting sensor
  3. Select 'sensor details'
  4. Select 'front gears'
  5. You can now select your chainring size(s) in 'gear presets', or if you cannot find your chainring combination listed, you can manually input the sizes (Gear 1 = virtual small ring (your big ring mutiplied with 0.7), Gear 2 = big ring, your actual chainring)

NOTE: on Garmin devices you can only add one ANT+ sensor. So you can either add your rear derailleur to display your cassette sprocket, or your Classified thru axle, to display the chainring size you are riding in.


1.3 Display gearing and battery status

To display the battery status of your Classified thru axle and handlebar unit or ringshifter, you can add a data field to your screen.

  1. Select Menu > Settings > Activity Profiles.
  2. Select a profile.
  3. Select Data Screens > Add New > Data Screen.
  4. Select a category, in this case 'Gears' and select 'Front Gears' and 'Battery shifter' as data fields.
  5. Select Back arrow symbol.
  6. Select an option.
      1. Select another category to select more data fields.
      2. Select Done.
  7. Select Up arrow symbol or Down arrow symbol to change the layout.
  8. Select Enter menu symbol.
  9. Select an option.
      1. Select a data field, then select another data field to rearrange them.
      2. Select a data field twice to change it.
  10. Select Done.

2. Wahoo

2.1 Pairing your Wahoo with the Classified thru axle

Pairing is possible with the following devices: Wahoo ELEMNT and BOLT. Before you pair, make sure your Wahoo is paired to the ELEMNT app.

  1. Shake your thru axle or move your bike to wake up the sensor.
  2. Press the Power button on the left side of the Wahoo head unit to enter settings.
  3. Use the down button on the right side of the device to scroll down to ADD SENSOR.
  4. Follow instructions to hold the Wahoo head unit close to the Classified thru axle for identification.
  5. Once it is recognized, add the sensor.

2.2 Setting up chainring sizes

Now go the Wahoo ELEMNT app to complete the pairing.

  1. On the ELEMNTmobile app press SETTINGS on the lower right of the screen.
  2. Scroll down to the SENSORS section and press SET UP SENSORS.
  3. Press GEARS
  5. Select the number of chainrings you have and then enter the number of teeth for the chainring(s). Then press DONE.
  6. Under the Rear Gear Ratio section, select 12 in the cassette section.
  7. Press CUSTOM to select the gear range.
  8. Select the cassette you are using. Press BACK on the top left of the screen to complete the process.


If you have a bike computer not listed above that can receive Bluetooth or ANT+ signals, it may be compatible with your Classified thru axle.
