💡 Note: Unlike older versions, there's no need to pair sensors or record rides inside the Xert app. All rides should be recorded using Karoo's native recording.  Xert EBC will automatically configure and re-use your Karoo sensors.

Sync Hammerhead Rides to Xert

  1. Link Your Xert and Hammerhead Accounts
    • Log in to the Hammerhead Dashboard.
    • Go to Accounts, find Xert and click Connect.
    • Follow the prompts to sign into Xert and accept the permissions.
  2. Automatic Ride Sync
    • Once connected, rides recorded on your Karoo will automatically upload to Xert. Activities will appear in your Xert Activities Feed and impact your Training Status.

⚠️ Tip: If you want Xert’s training summary included in your Strava uploads, disable Hammerhead → Strava syncing and let Xert handle the sync instead. See this FAQ for details.

Troubleshooting Common Issues

  • MPA / XSS showing “No Sensor” or not Updating?
    • Restart your Karoo device, in particular if you have updated EBC.  You can conveniently do this even while a recording is in-progress without losing your activity
  • EBC App Not Launching?
    • Ensure MPA is correctly added to your profile.
    • Check for updates in the extensions menu.
  • Ride Not Syncing to Xert?
    • Confirm your Xert account is properly linked in the Hammerhead Dashboard under Connected Accounts.
    • Xert prevents duplicates — syncing can occur from either Hammerhead or Strava, not both.
  • Data Fields Not Appearing?
    • Remove and re-add the MPA data field.
    • Reinstall the EBC app from Extensions for a fresh setup.

Conclusion

The Xert EBC app on Hammerhead Karoo offers a smarter, simpler way to train. With automatic syncing, real-time training guidance, and the power of Magic Buckets, you can execute and adapt your training with confidence.
