FAVERO ASSIOMA PRO RL-1 – Look® Keo Compatible Power Meter Pedals
Product Description
The Favero Assioma PRO RL-1 is a next-generation pedal-based power meter system designed for road cyclists who demand accurate power measurement, advanced cycling dynamics and exceptional reliability. Fully compatible with the Look® Keo® cleat standard, it combines Italian engineering precision with cutting-edge technology to help riders train smarter and perform at their best.
The Assioma PRO RL is one of the lightest Look® Keo-compatible power meter pedals on the market and features a fully adjustable release tension system, allowing riders to customize the clipping-in and clipping-out feel according to their personal preferences.
Built to deliver reliable and accurate data not only in laboratory conditions but also in real-world riding situations, the Assioma PRO RL provides the consistency required for serious training and performance analysis.
With an impressive battery life of up to 160 hours, riders can focus on training and racing instead of charging. Thanks to the advanced auto-calibration system, no regular manual calibration is required, ensuring a true plug-and-play experience.
A New Standard in Power Measurement
At the heart of the Assioma PRO RL is Favero's proprietary IAV Power System (Instantaneous Angular Velocity) technology, which guarantees ±1% accuracy, even when using oval chainrings.
Unlike conventional power meters that can be affected by variations in pedaling cadence and chainring shape, the IAV system continuously calculates power using real-time angular velocity measurements, ensuring consistent and highly accurate data under all riding conditions.
To further improve measurement reliability, the system incorporates ATC (Automatic Temperature Compensation) technology, which automatically compensates for temperature fluctuations and maintains stable power readings in both hot and cold environments.
Advanced Cycling Metrics for Smarter Training
The Assioma PRO RL delivers far more than basic wattage data. It provides a complete suite of advanced cycling dynamics metrics designed to help riders analyze and improve pedaling efficiency and technique.
Available metrics include:
• Power
• Cadence
• Left/Right Balance
• Platform Centre Offset (PCO)
• Power Phase (PP)
• Rider Position (RP)
• Pedal Smoothness (PS)
• Torque Effectiveness (TE)
These advanced metrics provide valuable insights into rider biomechanics and can help optimize performance, efficiency and comfort.
PCO – Platform Centre Offset
One of the most innovative features of the Assioma PRO RL is Platform Centre Offset (PCO), a metric available on only a limited number of power meters on the market.
PCO measures how force is distributed across the pedal platform, helping riders identify:
• Pedaling asymmetries
• Cleat positioning issues
• Muscle imbalances
• Pedaling inefficiencies
• Potential injury risks
By revealing how force is applied during each pedal stroke, PCO can help riders refine both pedaling technique and bike fit for improved performance and comfort.
Protected Sensors Inside the Spindle
Favero's patented design places the strain gauges, battery and electronics entirely inside the spindle.
This innovative solution offers several important advantages:
• Maximum measurement consistency
• Protection from water, dust and humidity
• Increased long-term reliability
• Improved durability
• Reduced risk of sensor contamination
The entire system is protected to an IP67 waterproof rating, ensuring reliable performance in all weather conditions.
Look® Keo Compatibility Without Compromise
The Assioma PRO RL is fully compatible with the Look® Keo® cleat system and delivers exceptional power transfer thanks to its large 755 mm² contact surface.
Compatible cleats include:
• Included Favero cleats
• Favero Look®-compatible cleats
• Look® Keo cleats
• Look® Keo Grip cleats
The adjustable release tension allows riders to fine-tune engagement and disengagement force according to their riding style and preferences.
Lightweight Performance
At just:
• 130 g for the left pedal with power sensor
• 129 g for the right pedal
the Assioma PRO RL is among the lightest Look®-compatible power meter pedals available with adjustable release tension.
This low weight is achieved through a pedal body manufactured from carbon-fibre reinforced technopolymer, combined with extensive engineering and development work.
Optimized Ergonomics
The Assioma PRO RL is designed to promote a natural and efficient riding position.
Key dimensions include:
• Stack Height: 10.5 mm
• Q-Factor: +53 mm
• Contact Surface: 755 mm²
The low stack height improves power transfer efficiency and creates a direct connection between rider and bicycle.
Connectivity and Compatibility
The Assioma PRO RL offers universal compatibility with modern cycling computers, indoor training platforms and smartphone applications.
Connectivity options include:
• ANT+
• Bluetooth Low Energy (BLE)
• Up to 3 simultaneous Bluetooth connections
Compatible with:
• Garmin
• Wahoo
• Hammerhead
• Zwift
• TrainerRoad
• Other ANT+ and Bluetooth-enabled devices and applications
The Favero Assioma App provides easy access to pedal activation, firmware updates, performance monitoring and advanced configuration settings.
Battery and Charging
The Assioma PRO series offers one of the longest battery lives available among pedal-based power meters.
Features include:
• Rechargeable lithium-ion battery
• Up to 160 hours of battery life
• Magnetic charging system
• Simultaneous charging of both pedals
• Fast charging capability
• 15 minutes of charging provides up to 15 hours of riding
The magnetic charging system makes recharging quick, simple and convenient.
Easy Installation and Automatic Calibration
The Assioma PRO RL can be installed on virtually any compatible bicycle in just a few seconds, without requiring special tools or complicated procedures.
Thanks to the advanced automatic calibration system:
• No periodic manual calibration is required
• Continuous measurement optimization
• Ready-to-ride operation at all times
Simply install the pedals and start riding.
Modular Design – Road and MTB Compatibility
Favero's unique split-approach design separates the spindle from the pedal body, allowing the latter to be replaced independently.
Benefits include:
• Interchangeable pedal bodies
• Easy transition between road and MTB setups
• Reduced maintenance costs
• Extended product lifespan
• Full serviceability
Replacement parts are available, allowing riders to maintain, repair or customize their pedals over time.
