Bike Fit Measurements

Bike Fit Measurements in Componentry help you record, track, and compare your bike positioning over time. Whether you've had a professional bike fit or dialed in your own setup, keeping accurate records ensures you can maintain consistency, replicate your position on new bikes, and track how your fit evolves.

What are Bike Fit Measurements?

Bike Fit Measurements are a comprehensive record of your bike's setup and your position on it. This includes everything from saddle height and handlebar reach to cleat position and frame geometry. Each measurement set captures a snapshot of your bike fit at a specific point in time.

In Componentry, measurements are organized by bike (gear) and stored as versions. This allows you to track changes over time, compare before and after adjustments, and maintain a complete history of your bike fit evolution.

Why Track Your Bike Fit?

Maintain Consistency

Once you've found a comfortable and efficient position, you want to keep it. Recording your measurements means you can:

• Restore your position after maintenance or travel
• Set up a new bike to match your existing fit
• Verify nothing has shifted after a crash or transport

Track Adjustments Over Time

Your ideal fit may evolve as your flexibility, fitness, or riding style changes. Version history lets you:

• See how your position has changed over months or years
• Compare measurements before and after adjustments
• Revert to a previous setup if a change doesn't work out

Collaborate with Bike Fitters

Professional bike fitters appreciate detailed records. With your measurement history you can:

• Share your current setup before an appointment
• Document the changes made during a fit session
• Reference specific measurements in discussions

Recover from the Unexpected

Crashes, rebuilds, and major component changes can disrupt your fit. Having records means:

• Quickly restoring your position after repairs
• Knowing exactly what changed if something feels off
• Documenting your setup for insurance or warranty purposes

Measurement Categories

Componentry organizes bike fit measurements into six categories, covering over 35 individual measurements. You don't need to record every measurement - only fill in what you have or what's relevant to your setup.

Saddle

Measurements related to your saddle position and setup:

• Saddle height (from bottom bracket to saddle top)
• Saddle setback (horizontal distance from bottom bracket)
• Saddle angle (tilt in degrees)
• Saddle fore/aft position
• Saddle width and length

Handlebar

Measurements for your handlebar setup:

• Handlebar width
• Handlebar drop (road bars)
• Handlebar reach (road bars)
• Handlebar rise (flat/MTB bars)
• Handlebar rotation angle

Stem

Stem-specific measurements:

• Stem length
• Stem angle
• Spacer stack height

Cockpit

Overall position measurements that define your riding posture:

• Stack (vertical height from bottom bracket to handlebar)
• Reach (horizontal distance from bottom bracket to handlebar)
• Saddle-to-handlebar drop
• Saddle-to-handlebar reach

Cleat

Cleat and foot positioning:

• Cleat fore/aft position
• Cleat rotation
• Cleat lateral position
• Q-factor / stance width

Frame

Reference geometry measurements (useful when comparing across bikes):

• Seat tube length
• Effective top tube length
• Head tube length
• Frame stack and reach

Key Features

Partial Measurements

You don't need to fill in every field. Record only the measurements you have - empty fields are simply omitted. Each category shows a badge indicating how many measurements are filled.

Fit Date

Each measurement set includes a fit date - the date the measurements were taken. This is separate from when the record was created, allowing you to accurately document when a fit was performed.

Names and Notes

Give each measurement set a descriptive name like "Initial Setup", "Post-Fit Session", or "Winter Position". Add notes to record context, conditions, or observations.

Version History

Every measurement set is saved as a version. You can view any previous version, compare versions side-by-side, and track how your fit has evolved.

Side-by-Side Comparison

Select two versions to compare directly. Differences are highlighted, making it easy to see exactly what changed between measurements.

Getting Started

1. Navigate to Bike Fit

From your gear list, click the Ruler icon on any bike card. Or from the gear detail page, click the Fit button in the header next to Settings.

2. Record Your First Measurement

Click "New Measurement" to open the measurement form. Select the fit date, add an optional name and notes, then expand each category and enter your measurements.

3. Save Your Measurements

Click "Save Measurements" to create your first version. You can always edit later or add more measurements as you obtain them.

4. Track Changes Over Time

After adjustments or new fit sessions, create new measurement versions to build your fit history. Use the comparison feature to see what changed.
