Assigning Components to Profiles

Once you've created profiles on a bike, you can assign individual components to them. This controls which activities contribute to each component's wear calculation.

Understanding the Two Types of Components

Default Components (No Profile)

Components without a profile assignment are default components. Their wear accumulates from every activity on the bike, regardless of which profile is active.

Assign to default when the component:

• Stays on the bike permanently (frame, handlebars, seatpost, stem)
• Is used across all setups (brake pads, cables, housing, bar tape)
• Doesn't change between configurations

Profiled Components

Components assigned to a profile only accumulate wear from activities where that profile is active.

Assign to a profile when the component:

• Gets swapped in and out (wheels, chains, cassettes, tyres)
• Is only used in a specific configuration (race-day components, indoor trainer parts)
• Should not accumulate wear from rides where it wasn't installed

Assigning a Profile When Creating a Component

When your bike has profiles, a Profile dropdown appears in the component creation form:

1. Open the Add Component sheet from your bike's detail screen.
2. Fill in the component details (name, type, manufacturer).
3. Select a profile from the Profile dropdown, or leave it as Default (all activities).
4. Complete the rest of the form and save.

The component is created with the selected profile assignment.

Changing a Component's Profile

You can change a component's profile assignment at any time:

1. Open the component's edit sheet by clicking the edit icon on your bike's detail screen.
2. Change the Profile dropdown to the desired profile, or set it to Default (all activities) to remove the profile assignment.
3. Save the changes.

What Happens When You Change a Profile

When a component's profile changes, Componentry automatically recalculates its wear based on the new set of matching activities:

• Moving to a profile: The component's wear is recalculated using only activities with that profile. Wear may decrease if the component was previously counting all activities.
• Moving to default: The component's wear is recalculated using all activities on the bike. Wear may increase as it now counts rides from every profile.
• Switching profiles: Wear is recalculated using only activities matching the new profile.

This recalculation happens automatically — you don't need to trigger it manually.

Example Setup

Here's a common setup for a road bike with training and race wheels:

Training Profile

• Front wheel: DT Swiss PRC 1400 Front
• Rear wheel: DT Swiss PRC 1400 Rear

Race Profile

• Front wheel: Zipp 404 Firecrest Front
• Rear wheel: Zipp 404 Firecrest Rear

Default (No Profile)

• Frame
• Chain
• Cassette
• Brake pads
• Bar tape
• Groupset components

In this setup, the training wheels only accumulate wear from rides using the Training profile, the race wheels only from Race profile rides, and everything else (frame, chain, cassette, etc.) accumulates wear from all rides.

Identifying Profiled Components

On your bike's detail screen, profiled components display a badge showing the profile name next to the component name. Default components have no badge.

This makes it easy to see at a glance which components belong to which setup.
