3. Setup
3.1. Pedal Installation
The Assioma PRO MX-2 pedals are designed for easy installation, similar to standard bicycle pedals. No special tools are required beyond a pedal wrench.
- Ensure your crank arms are clean and free of debris.
- Apply a small amount of grease to the pedal threads.
- Identify the left (L) and right (R) pedals. The right pedal threads clockwise, and the left pedal threads counter-clockwise.
- Carefully thread each pedal into its respective crank arm by hand to avoid cross-threading.
- Use a pedal wrench to tighten the pedals securely. Refer to your crank manufacturer's specifications for torque values, typically around 35-40 Nm.
- If your crank arm requires washers to prevent contact with the pedal body, install them as needed. Four washers are included in the package.

3.2. Cleat Installation
The Assioma PRO MX-2 pedals are 100% SPD compatible. You can use the included 4-degree float cleats or original Shimano SM-SH51 cleats.
- Attach the cleats to your MTB shoes according to the cleat manufacturer's instructions.
- Adjust the cleat position for optimal comfort and pedaling efficiency.
3.3. Pairing with Devices
The Assioma PRO MX-2 pedals transmit data via Bluetooth and ANT+ connectivity, allowing pairing with various cycling GPS computers, smartphones, and other compatible devices.
- Ensure your cycling computer or smartphone is powered on and Bluetooth/ANT+ is enabled.
- Rotate the pedals a few times to wake them up.
- On your device, navigate to the sensor pairing menu.
- Select the Assioma PRO MX-2 from the list of available sensors.
- Follow any on-screen prompts to complete the pairing process.
4. Operating
4.1. Power Measurement and Accuracy
The Assioma PRO MX-2 utilizes a dual-sensing system, measuring power independently from both pedals. Its IAV Power System, incorporating a three-axis gyroscope, accounts for variations in pedaling dynamics, ensuring a high degree of accuracy (±1%) in real-world conditions. Automatic Temperature Compensation (ATC) maintains consistent measurements across temperatures from -10°C to 55°C.

4.2. Advanced Cycling Metrics
Beyond basic power and cadence, the Assioma PRO MX-2 provides a suite of advanced cycling metrics for detailed analysis:
- Power (W): Total power output.
- Cadence (RPM): Pedaling revolutions per minute.
- L/R Balance (%): Percentage of power generated by the left and right legs.
- Platform Center Offset (PCO): Indicates where force is applied on the pedal platform.
- Power Phase (PP): Shows the angle at which power is applied during the pedal stroke.
- Pedal Smoothness (PS): Measures the uniformity of power application throughout the pedal stroke.
- Torque Effectiveness (TE): Quantifies the percentage of positive torque applied to the pedal.
- Rider Position: Detects if the rider is seated or standing.

5. Maintenance
5.1. Charging
The Assioma PRO MX-2 pedals feature integrated rechargeable batteries. A single charge provides over 60 hours of operational use. Charging is performed via a magnetic system to ensure a secure connection and prevent damage from accidental tugging.
- Connect the magnetic charging connectors to the charging ports on each pedal.
- Connect the USB Type-C 2-way Charging Cable to the magnetic connectors and a suitable USB power source.
- The LED indicator on the pedals will show the charging status. Refer to the Favero Assioma app for detailed battery levels.
5.2. Cleaning
Regular cleaning helps maintain the performance and longevity of your pedals.
- Wipe the pedal bodies with a damp cloth after each ride, especially after riding in wet or muddy conditions.
- Avoid using high-pressure washers directly on the pedals, as this can force water into the sealed components.
- Use the provided RiseUP Cleaning Cloth for gentle cleaning.
5.3. Durability
The pedals are constructed with an aluminum 6061-T6 pedal body, designed for robustness and light weight. The clipless system features a surface hardness of up to 800 HV, providing resistance to impacts. All electronic components and the integrated rechargeable battery are safely sealed within a compact and resistant spindle, minimizing the risk of damage from external elements.
6. Troubleshooting
If you encounter issues with your Assioma PRO MX-2 pedals, consider the following common solutions:
- No Power Reading:
- Ensure pedals are awake by rotating them a few times.
- Check battery level via the Favero Assioma app and recharge if necessary.
- Verify that the pedals are correctly paired with your cycling computer or smartphone.
- Inconsistent Readings:
- Perform a zero-offset calibration (also known as manual calibration) through your cycling computer or the Favero Assioma app before each ride or when changing environmental conditions.
- Ensure pedals are clean and free from obstructions.
- Check for any physical damage to the pedals.
- Connectivity Issues:
- Ensure Bluetooth/ANT+ is enabled on your receiving device.
- Move closer to the pedals if experiencing signal drops.
- Try unpairing and re-pairing the pedals with your device.
- Check for firmware updates for both the pedals and your cycling computer.
- Pedal Body Swapping:
- The modular design allows swapping pedal bodies between PRO MX (MTB) and PRO RS (Road) setups. Ensure the power sensor is correctly transferred and secured when swapping.
