Favero Assioma UNO Power Meter Pedals

The Favero Assioma UNO are road pedals with a power meter integrated into the left pedal. Compatible with LOOK Kéo® cleats, they precisely measure power and cadence without modifying the bike's crankset.

The power developed by the left leg is measured with an accuracy of ± 1%, then multiplied by two to estimate total power. Rechargeable, waterproof, and easy to transfer from one bike to another, the Assioma UNO are a reliable and accessible solution for starting power-based training.

• Quick installation and transfer
• Upgradeable to the Assioma DUO system
• Italian design and manufacturing

Unilateral Power Measurement

The sensor is integrated into the left pedal. It measures the power developed by the left leg, then doubles this value to estimate total power.

This unilateral solution effectively tracks:

• Instantaneous power
• Average power
• Cadence
• Left leg power phase
• Seated or standing position
• Torque effectiveness
• Pedaling smoothness

The Assioma UNO is perfectly suited for cyclists who want to structure their training based on power zones without needing an independent analysis of both legs.

± 1% Accuracy

The IAV Power System technology calculates power from instantaneous angular velocity. An integrated gyroscope precisely analyzes variations in motion throughout the pedal stroke.

The system thus maintains an accuracy of ± 1% during accelerations, cadence changes, or standing out of the saddle. It is also compatible with the use of an oval chainring.

LOOK Kéo® Compatibility

Assioma UNO pedals are compatible with:

• Favero LOOK Kéo compatible cleats
• LOOK Kéo® cleats
• Three-hole road cycling shoes

A pair of Favero LOOK Kéo cleats with 5° of angular float is included. This mobility offers a good compromise between foot retention, joint comfort, and pedaling efficiency.

Simple Installation

The pedals install directly onto the crank arms like a standard pair of pedals. No changes to the crankset, crank arm, or bottom bracket are necessary.

They can also be quickly transferred between multiple bikes, making them particularly convenient for cyclists using a training bike and a race bike.

Automatic Temperature Compensation

The ATC – Active Temperature Compensation system automatically corrects the influence of temperature variations on recorded data.

This ensures the measurement remains stable and consistent as climatic conditions change during the ride.

Over 50 Hours of Battery Life

The integrated lithium battery provides over 50 hours of use per charge.

Recharging is done directly on the pedal using the included magnetic connector. This design avoids the use of replaceable batteries and limits openings that could lead to water infiltration.

ANT+ and Bluetooth Connectivity

Assioma UNO pedals transmit data via ANT+ and Bluetooth. They can be paired with major:

• GPS bike computers
• Multisport watches
• Smartphones and tablets
• Training applications
• Virtual cycling platforms

They are particularly suitable for use with Zwift, TrainerRoad, Rouvy, and other compatible applications.

An Upgradeable Solution

The Assioma UNO can later be converted into a dual-sided system with the Assioma UNO Upgrade kit.

Adding a right pedal with a sensor then provides independent measurement of both legs, as well as true left/right balance, just like with the Assioma DUO.

Who are the Favero Assioma UNO for?

These pedals are recommended for:

• Cyclists looking to start power-based training
• Triathletes wanting to better manage their effort
• Users of LOOK Kéo cleats
• Athletes seeking an accurate and easy-to-install power meter
• Cyclists using multiple bikes
• Riders who want the option to upgrade to dual-sided measurement later

Triathlon Store Advice

The Assioma UNO represents an excellent entry point into power-based training. Its unilateral measurement is sufficient for managing zones, calibrating sessions, and better controlling effort in triathlon.

For athletes with known asymmetry or those wishing to analyze each leg separately, we recommend the Assioma DUO instead. However, the UNO remains upgradeable thanks to the dedicated upgrade kit.

After installation, remember to accurately enter your crank arm length into your head unit or watch to ensure data reliability.

In Summary

The Favero Assioma UNO offers precise power measurement in a simple, rechargeable, and easy-to-install format. Their LOOK Kéo compatibility, ± 1% accuracy, and upgradeability to the DUO system make them a particularly relevant solution for starting power meter training.
