Auto updating a Bike on a Strava activity

Once this is set up, every new ride shows the correct bike on its Strava activity — no manual editing. Three things have to be in place: a connected head-unit app sending the FIT file to Componentry, a sensor paired on the Sensors page to both a Componentry bike and a Strava bike, and Strava itself connected.

Step 1 — Connect a FIT-file-compatible app on the Apps page

Componentry identifies which bike you rode from sensor IDs inside the FIT file. Strava strips most of that data on upload, so we need the original FIT from your head unit. Open the Apps page and connect the app that matches your head unit:

• Garmin Connect
• Wahoo
• Hammerhead

While you're on the Apps page, also connect Strava — that's the account Componentry will update with the right bike after each ride.

Step 2 — Pair a sensor on the Sensors page

Open the Sensors page. Each sensor that's appeared in a recent ride is listed here. For every bike you want updated on Strava, pick one sensor that lives on that bike (a power meter is the most reliable choice) and do two things on the same row:

1. Pair it to a Componentry bike — so Componentry knows which of your bikes the ride belongs to.
2. Link it to the matching Strava bike — so the Strava activity can be updated with the right Strava bike.

Both links are required. Pairing only the Componentry bike will match the ride internally but leave the Strava activity untouched.

Step 3 — Ride. Strava gets updated automatically

On your next ride:

1. Your head-unit app syncs the FIT file to Componentry.
2. Componentry reads the sensor IDs and matches the ride to the paired Componentry bike.
3. Componentry finds the corresponding Strava activity and sets its bike to the linked Strava bike.

No editing the activity in Strava afterwards.

Troubleshooting

The Componentry bike matched but Strava wasn't updated

• Check the sensor row on the Sensors page has a Strava bike linked, not just a Componentry bike.
• Confirm Strava is still connected on the Apps page.

The ride didn't match a Componentry bike at all

• Confirm the sensor used on that ride is paired on the Sensors page.
• Confirm the FIT file actually reached Componentry — it should appear in your activity list within a few minutes of the head-unit sync.

Wrong Strava bike showed up

• The sensor is probably linked to the wrong Strava bike, or the same sensor is being used on more than one physical bike. Re-check the link on the Sensors page.
