Cycling Dynamics data lost

My Edge 1040 no longer displays Cycling Dynamics, although I can still view the Cycling Dynamics data on my Forerunner 970 watch.

I tried syncing the Edge 1040 using the Garmin Connect app, but the Cycling Dynamics data still does not appear. Other data, such as history records, sync successfully to the Edge 1040.

Could anyone, or the developers, advise how to resolve this issue?

Thank you.

  • did you try to remove the paired power sensor on the Edge, re-pair and toggle all the CD buttons on in the sensor menu?

  • Sorry, I made a typo earlier — it’s not Cycling Dynamics, it’s Cycling Ability.

    My power pedal works fine with both my FR970 watch and Edge 1040, and both devices can measure power during cycling. However, only the watch shows Cycling Ability, while the Edge 1040 does not.

    I already tried re-pairing the connection between the Edge 1040 and my phone, but the Cycling Ability data still does not appear. Other power data syncs correctly.

  • Are you sure that your heart rate strap is connected to the 1040?

    You won't get a vo2max calculation and therefore no cycling ability calculation without heart rate.

  • a bit different :D 

    so, i assume your 970 is your primary training device (and primary wearable, ofc) on Connect, so somewhy the TrueUp sync is not working? i have 965 and 840 , the 965 is the primary training device and wearable and everything is synced to the 840, the Cycling Ability also (fw25.04  and 28.33). 

  • Yes, the 970 is my primary device. Recently, after my 1040 was upgraded with the latest software, I could no longer see any Cycling Ability data on the 1040. Today, after syncing my 970 watch with Garmin Connect, the Cycling Ability data and activities in Garmin Training Coach also disappeared. I suspect there may be a bug in Garmin Connect that is preventing proper synchronization across these devices.

  • how do you try to sync, via BT, via Wifi or via USB with Garmin Express?

  • yes, I always wear my heart trap during training. Before this update, I always can see my cycling ability in my 970 and 1040.

  • I sync through the BT or wifi. And I tried to use Garmin express yesterday. The situation is still occurred.
