Best Head Unit Settings for Assioma Pedals (2025 Guide)

Favero Assioma pedals are famous for their accuracy, stability, and simplicity. They pair effortlessly with most bike computers — Garmin, Wahoo, Hammerhead Karoo, Bryton, Lezyne, and even indoor apps like Zwift, Rouvy, and TrainerRoad.

But to get the most accurate power, cleanest cadence, and meaningful training data, your head unit needs to be set up properly. The right settings can dramatically improve your experience — especially during intervals, FTP testing, or long outdoor rides.

This guide walks you through the best cyclometer/head unit settings for Assioma pedals in 2025, whether you're using UNO or DUO.

1. Start With the Essentials: Required Settings for Assioma Accuracy

Before adjusting data screens, make sure the foundational settings are correct.
Correct Crank Length: Assioma accuracy depends on the correct crank arm length being entered (e.g., 165mm, 170mm, 172.5mm, 175mm).
You can set this:

• In the Assioma app, or
• Directly in Garmin/Wahoo settings if supported

Mismatched crank length = incorrect torque readings.

Calibration / Zero Offset Before Every Ride: Always perform a manual zero offset after mounting your bike and before rolling out.

How:

• Pedals vertical
• No weight on pedals
• Bike upright

This stabilizes temperature drift and ensures true baseline readings.

Use ANT+ for Head Units (When Available): Assioma supports Bluetooth & ANT+.
But for bike computers:
ANT+ is the most stable and reliable

• Faster response
• Fewer dropouts
• Cleaner power & cadence transmission

Use Bluetooth for phones/tablets only.

Disable External Cadence Sensors: Assioma provides cadence internally via gyroscopic measurement. If your head unit tries to read cadence from another sensor (e.g., magnet or crank-based sensor), your readings may jump around.

Remove or unpair any extra cadence sensors.

2. Best Head Unit Data Screens for Assioma Pedals

Now let’s build the perfect data pages based on training purpose. The key is reducing clutter while maximizing useful real-time feedback.

Primary Ride Page (For Most Riders): This should be your “always visible” screen. Recommended fields:

• 3-second power (smooths noise, still reactive)
• Cadence (from Assioma)
• Speed
• Heart Rate
• Distance / Duration

Why 3-second power?
Instant power jumps too much to be useful; 3s is the sweet spot for road & indoor training.

Advanced Training Page (Intervals / FTP Work)

Use this page during structured training:

• Instantaneous Power
• 3-second Power
• Lap Power
• Normalized Power (NP)
• Intensity Factor (IF)
• Heart Rate Zone

These values help you pace intervals perfectly.

Climbing Page (Hill Training)

When climbing, focus shifts to rhythm and pacing:

• 10-second Power (smoothed for long, steady efforts)
• Power-to-Weight (W/kg)
• Gradient
• Cadence
• Elapsed Climb Time

Assioma shines on climbs because IAV Power stabilizes readings at low cadence.

Indoor Training Page (Zwift / TrainerRoad)

Indoor riding needs different metrics:

• Cadence
• 3-second Power
• ERG-mode Target Power
• Heart Rate
• Left/Right Balance (DUO)
• Pedal Smoothness (if supported)

You don’t need:

• Speed
• GPS
• Elevation

Disable them indoors to simplify screens.

Sprint Page (Explosive Efforts / Testing)

For max power efforts:

• Instant Power
• Max Power (lap or session)
• Cadence
• Heart Rate (post-sprint recovery)
• Lap Time

Assioma performs exceptionally well in sprints due to IAV angular velocity measurement.

3. Advanced Assioma Settings to Enable

Left/Right Balance (DUO only): Ideal for:

• Strength imbalance detection
• Injury recovery
• Pedal technique refinement

Most Garmin & Wahoo head units support:

• L/R balance
• Pedal smoothness
• Torque efficiency

Auto Zero / Temperature Compensation: Enable auto-zero when pausing or unclipping.

Assioma adjusts for temperature throughout the ride, but a starting zero-offset makes it even more stable.

4. Tips to Avoid Data Problems

Make sure pedals are installed at 35–40 Nm: Loose pedals = incorrect torque.
Keep firmware updated via Assioma app: Favero frequently refines stability & accuracy.
Charge regularly: Battery lasts long (50+ hours), but don’t risk mid-ride drops.
Use 3s or 10s power, NOT instantaneous, for pacing: Your pacing will improve immediately.

5. Example Setup (Garmin, Wahoo, Karoo)

Garmin Edge

• Pair as Power Sensor + Cadence Sensor
• Enable Cycling Dynamics fields
• Turn on Auto-Zero
• Configure Power Phase, Torque Efficiency if desired

Wahoo ELEMNT/Bolt/Roam

• Auto-detect Assioma
• Disable external cadence
• Place 3s Power and Cadence prominently
• Enable Left/Right Balance on DUO

Hammerhead Karoo 2

• Choose ANT+
• Add custom power pages with 3s, NP, IF
• Add battery indicator widget

6. Why Proper Head-Unit Setup Matters

A poorly configured head unit can make an accurate power meter seem inconsistent.
A well-configured head unit makes your Assioma data:

• Smooth
• Stable
• Easy to pace with
• Perfect for training progressions
• Ideal for indoor/outdoor consistency

Correct screens = better workout quality = better training outcomes.

Conclusion

The Favero Assioma is one of the most accurate and consistent pedal power meters available — but your head unit setup determines how useful that accuracy becomes. With the right screens (3-second power, cadence, NP, IF, balance), correct pairing, and proper crank length and calibration settings, you can unlock the full potential of your Assioma pedals on every ride.
