Profiles and Activities

Profiles connect to activities to determine which components accumulate wear from each ride. This page explains how profiles are assigned to activities and what happens when you change them.

Automatic Profile Assignment

When a new activity is matched to a bike, Componentry checks if the bike has a default profile set. If it does, the activity is automatically assigned that profile.

This works across all activity sources:

• Device matching — When a FIT file contains a device linked to a bike, the activity gets the bike's default profile.
• Strava sync — When a Strava activity is matched to a bike via the Strava gear mapping, the default profile is applied.
• Strava import — Bulk-imported Strava activities also receive the default profile.

If the bike has no default profile, the activity is assigned to the bike with no profile. In this case, only default components (those without a profile) accumulate wear.

Viewing the Profile on an Activity

When you open an activity's detail sheet from the Activities page, you'll see the assigned bike and — if the bike has profiles — the currently selected profile.

The profile appears as a dropdown below the bike selector.

Changing the Profile on an Activity

You can change the profile on any activity, including past activities:

1. Open the activity's detail sheet from the Activities page.
2. In the Bike section, select the bike (if not already assigned).
3. A Profile dropdown appears below the bike selector showing the available profiles.
4. Select the correct profile for this activity.
5. Click Save Bike to apply.

What Happens When You Change a Profile

Changing the profile on an activity triggers a wear recalculation for the bike's components:

• Profiled components matching the old profile lose the wear contribution from this activity.
• Profiled components matching the new profile gain the wear contribution.
• Default components are unaffected — they always count all activities regardless of profile.

The recalculation happens automatically after saving.

When No Profile is Selected

If an activity has no profile (profile set to "None" or "No profile"):

• Default components accumulate wear from this activity as normal.
• Profiled components do not accumulate wear from this activity, regardless of which profile they belong to.

This is the correct behavior — if you didn't specify a profile, the system assumes only the permanent (default) components were in use.

Common Workflows

Swapping Setups Between Rides

The typical workflow when you change your physical bike setup:

1. Swap your components (e.g. put on race wheels).
2. Go to your bike's detail screen and change the default profile to match (e.g. "Race").
3. Ride as normal — new activities automatically get the "Race" profile.
4. When you swap back, change the default profile again.

Correcting a Past Activity

If you forgot to switch the default profile before a ride:

1. Open the activity from the Activities page.
2. Change the profile to the one that matches the setup you actually used.
3. Save — wear is recalculated automatically.

Bulk Changes

If you need to correct the profile on many activities (for example, after forgetting to switch the default for a week), you can update each activity individually from the Activities page. Each change triggers an automatic wear recalculation.

Tips

• Set the default profile to match your current physical setup. This is the single most important step for accurate tracking.
• Change the default when you swap — do it right when you change your setup so you don't forget.
• Don't worry about mistakes — you can always go back and correct the profile on past activities. Wear recalculates automatically.
• Leave permanent components as default — only assign profiles to components you actually swap between setups.
