Sensors
See the sensors on your rides, name them, and pair them with a bike so rides are matched automatically.
A sensor is anything your head unit records on a ride: a power meter, speed or cadence sensor, a Shimano Di2 or SRAM AXS groupset, a heart rate strap or a smart trainer. Pair a sensor with the bike it's fitted to and every ride that sensor records is matched to that bike, so wear lands on the right components without you picking a bike after each ride.
Where sensors come from
Sensors appear on their own. Each time a ride arrives as a FIT file (from Garmin, Wahoo or Hammerhead on the Apps page, or from Upload FIT files on Activities), Componentry adds any new sensor it finds. Rides that only come from Strava don't include sensor details, so they don't add sensors.
When you import bikes from Strava on the Apps page, each imported bike also gets a Virtual sensor that stands in for its Strava bike. That's what lets Strava rides land on the right bike. See Setting your bike on Strava automatically.
The Sensors page
Open Sensors in the menu. Each sensor has a card showing:
- Name and serial number
- Type: Power Meter, Speed Sensor, Cadence Sensor, Speed/Cadence Sensor, Electronic Shifting, Virtual, Heart Rate Monitor or Trainer
- Paired Gear: the bike it's paired with, or Unpaired
- Profile: the profile pinned to it, Auto when it follows the bike's usual profile rules, or a dash while it's unpaired
- Strava Bike: the Strava bike it's linked to, or Not linked
- Edit to pair it, pin a profile or link a Strava bike, and the bin button to delete it
The number next to Sensors in the menu counts sensors that could be paired with a bike but aren't yet. With the menu collapsed, a dot marks Sensors instead; on a phone, the menu button shows the dot.
Heart rate monitors and trainers
Heart rate monitors and trainers are never used to decide which bike you rode: you wear the strap on every bike, and a trainer can carry any of them. Their cards have no pairing options and they don't count towards the unpaired number. Indoor rides can still find the right bike through an Indoor profile; see Auto-matching rides to bikes.
Electronic groupsets
A Di2 or AXS groupset shows up as Electronic Shifting. It stays on one bike, so it's one of the most reliable sensors to pair: rides it records go to that bike even when you move wheels or power pedals between bikes.
Naming a sensor
Your names show on the battery badges on Home and on each activity, and in low-battery notifications, in place of "UNKNOWN" or whatever the device reports.
- Open a ride that used the sensor and click its battery badge under Reported Electronics. This copies the ID rides use to recognise that sensor.
- On the Sensors page, click Add Sensor.
- Enter a Name, pick the Type and paste the ID into Serial number.
- Click Add Sensor.
The next ride that records the sensor is matched to the one you added, so you won't see a second, unpaired copy of it. This also works for sensors you added earlier with a serial number copied from a badge.
A sensor's type can't be changed once it's added. If a sensor with that serial number already exists on the Sensors page, you'll see "A sensor with this serial number already exists".
Deleting a sensor
Click the bin button on its card and confirm. If the sensor records on a later ride, it's added again, unpaired.
In the mobile app
Sensors live under Settings → Sensors in the mobile app, where you can add, pair, pin a profile and link a Strava bike. Each bike also has a Sensors card listing what's paired with it.
