Favero Assioma Pro RL-1 Power Pedals are elite, single-sided road power meters for Look Keo cleats. Housing all electronics inside a podless spindle, they deliver ±1% accurate data, automatic calibration, and a 160-hour battery life.
The Favero Assioma Pro RL-1 Power Pedals bring Favero's legendary power-measurement precision to road cyclists who ride the Look Keo cleat ecosystem. Meticulously designed and manufactured in Italy, this single-sided power meter marks a massive leap forward by eliminating the external battery pods found on previous generations. By integrating all the sensitive strain gauges, wireless antennas, and internal electronics completely inside the high-strength steel spindle, Favero has achieved a pristine, podless form factor. This advanced design keeps the weight incredibly low while shielding the delicate internal sensors from moisture, road grit, and crash damage.
Operating as a single-sided setup, the left pedal acts as the master unit containing the force sensors, capturing your precise left-leg power output and multiplying it by two to transmit total wattage and cadence to your head unit. Weighing a mere 130 grams for the power pedal, the Pro RL-1 stands as the lightest adjustable Look-compatible power meter pedal on the market. Unlike basic fixed-blade models, it retains a fully mechanical adjustment screw, allowing you to fine-tune your entry and exit clip tension to match your exact riding preference. The pedal body is formed from a carbon-fibre-reinforced technopolymer, sporting an oversized 755 square millimetre contact surface area that maximises structural stiffness, eliminates foot hotspots, and ensures optimal power transfer.
Data accuracy is where Favero commands the market, utilizing their proprietary IAV (Instantaneous Angular Velocity) Power System to guarantee a strict ±1% accuracy tolerance. Bolstered by an integrated gyroscope, the system tracks real-time variations in your pedal stroke speed, delivering perfectly true readings even if you run oval chainrings or have an erratic pedalling style on steep climbs. Active Temperature Compensation ensures data consistency in conditions ranging from -10°C up to +55°C, while the intelligent auto-calibration system handles zero-offsetting autonomously behind the scenes. Best of all, a massive internal rechargeable lithium-ion battery provides an industry-leading 160 hours of ride time on a single charge.
Podless Spindle Integration: Completely houses the rechargeable batteries, wireless electronics, and force sensors safely inside the axle for ultimate protection and clean bike aesthetics.
IAV Power & Gyroscope Technology: Utilises an internal gyroscope to track instantaneous angular velocity, ensuring ±1% accurate readings regardless of oval chainrings or shifting cadences.
160-Hour Rechargeable Battery: Features an ultra-long-lasting internal lithium-ion battery that yields up to 160 hours of ride time per charge, topped up via a convenient magnetic cable.
Carbon-Reinforced Platform: Built with a massive 755 mm² contact surface area made of carbon-fibre technopolymer to maximise foot stability and power transfer.
Adjustable Release Tension: Retains a traditional mechanical spring screw so riders can fully customise the clip-in and clip-out tension to their liking.

Look Keo Loyalists: Perfect if you want immediate, highly accurate power data on your road bike without being forced to abandon your preferred Look cleat system.
Cost-Effective Performance: Provides a premium, European-made power meter at a fraction of the cost of dual-sided units, capturing your essential metrics without the heavy price tag.
Unmatched Battery Longevity: Ideal for endurance athletes and bikepackers who want to go weeks or months between charges thanks to the class-leading 160-hour firmware optimization.
Zero-Fuss Calibration: The smart, integrated auto-calibration algorithm continually sets itself, allowing you to just clip in and ride without doing manual zero-resets before every loop.
Modular Ecosystem: Features a smart modular spindle design that allows you to swap the internal power axle into Favero's off-road MTB (MX) or Shimano (RS) pedal bodies down the track.
❌ Left/Right Balance Seekers: Because this is a single-sided system that simply doubles your left-leg wattage, riders looking to analyze true independent leg discrepancies should buy the dual-sided Pro RL-2 instead.
❌ Shimano Road Cleat Users: These pedal bodies are strictly tailored for Look Keo cleats; if your shoes are set up for Shimano SPD-SL cleats, you will need the Favero Pro RS-1 variant.
❌ Wall Plug Charging Prep: Unlike coin-cell battery units that swap out in thirty seconds, you must remember to connect the magnetic USB-C charging cable to a power source ahead of time.
Because the Assioma Pro RL-1 utilizes standard pedal threads, it can be swapped between multiple bikes in under two minutes using a standard open-ended pedal wrench. When installing them, always make sure to place the included pedal washers between the spindle shoulder and your crank arms if your cranks feature recessed faces or protective clear frameskin wraps. These washers ensure the internal sensor assembly never binds or gets compressed against the alloy or carbon face of the crank arm, completely preventing false data spikes or reading anomalies on your head unit!
