Zero-Friction Ingestion: 90-Day Auto-Backfill for Garmin, Wahoo, Zwift & Karoo
The Hassle of Moving to a New Fitness App
Most cyclists use different devices for different rides: a Garmin Edge on the road bike, a Wahoo on the gravel bike, a Hammerhead Karoo for bikepacking trips, and Zwift on winter mornings indoors. When trying a new platform, you are usually forced to manually export and upload dozens of individual activity files just to see your past fitness.
ChainLink eliminates that headache completely with our Automated Multi-Device Sync Pipeline.
Automatic 90-Day History Sync in the Background
The moment you link your Garmin Connect, Wahoo, Zwift, or Hammerhead Karoo account, ChainLink automatically reaches back and imports your last 90 days of rides in the background:
- No Waiting in Your Browser: The import runs in the cloud on background workers, so you don't have to keep your browser open or wait for progress bars.
- Instant Fitness Baselines: Within minutes, your complete Performance Management Chart and power records are calculated and ready to view.
- Smart Duplicate Cleaning: If you record a ride on your bike computer and your trainer at the same time, ChainLink automatically merges them so your training log stays clean and accurate.
Easy Bulk Strava ZIP Archive Import
If you have years of ride history in Strava, you don't have to leave it behind. ChainLink includes a simple Bulk Archive Dropzone: just drop in your Strava data export ZIP file, and ChainLink will import your full multi-year history in one batch.
This gives you complete freedom from subscription paywalls, ensuring your lifetime training data remains yours forever.
Connecting Your Devices in Your Profile
Connecting your devices takes less than two minutes. You can link your headunits during initial onboarding or at any time by heading to your Profile (/profile).
Inside your Athlete Profile card, look for the Integrations panel on the right side. You will see one-click connect buttons for Zwift, Garmin, Wahoo, and Hammerhead. Once connected, your rides sync automatically every time you finish pedaling.
