The Favero Assioma Pro RL-2 Power Pedals are ultra-light, dual-sided road power meters for Look Keo cleats. Delivering ±1% accurate IAV data, automatic calibration, and a 160-hour rechargeable battery, they maximize your performance.
The Favero Assioma Pro RL-2 Power Pedals represent the absolute pinnacle of dual-sided power measurement for road cyclists who prefer the Look Keo cleat standard. Meticulously designed and manufactured in Italy, these cutting-edge pedals refine your training by eliminating the awkward external battery pods found on older generations. By housing all the sophisticated electronics and wireless antennas completely inside the high-strength spindle, Favero has created a sleek, podless form factor that is virtually indistinguishable from a standard, non-power road pedal. This design protects the sensitive internals from crash damage, water ingress, and road grit, ensuring pro-level data collection season after season.
Weighing an astonishing 130 grams per pedal, the Pro RL-2 stands as the lightest Look-compatible power meter pedal on the market featuring a fully adjustable release tension system. Unlike stiff blade-spring designs, this mechanical adjustment screw allows you to easily dial in your exact entry and exit preference for absolute clipping confidence. The oversized 755 square millimetre contact surface area is crafted from carbon-fibre-reinforced technopolymer, providing an incredibly stable platform that prevents hot spots and optimizes every single watt of power transfer. With a slim 10.5mm stack height and a standard +53mm Q-factor, these pedals preserve your natural, efficient biomechanical riding position.
Data accuracy is where the Pro RL-2 truly outshines the competition, leveraging Favero's proprietary IAV (Instantaneous Angular Velocity) Power System to deliver a strict ±1% accuracy tolerance. By tracking your real-time pedal stroke speed using an integrated gyroscope, the system provides flawless readings even if you ride irregular oval chainrings or experience extreme pedalling variations on steep climbs. The advanced auto-calibration system handles all zero-offset adjustments automatically behind the scenes, while Active Temperature Compensation keeps your numbers perfectly consistent from chilly winter mornings through to scorching summer afternoons. Best of all, a massive firmware upgrade stretches the internal rechargeable lithium-ion battery life up to an industry-leading 160 hours per charge.
True Dual-Sided Measurement: Captures independent left and right leg data, providing deep insights into your total power output, cadence, and left/right muscle balance.
Podless Spindle Integration: Houses all rechargeable electronics directly inside the axle, reducing aerodynamic drag and shielding components from crashes.
IAV Power & Gyroscope Tech: Tracks instantaneous angular velocity for ±1% accurate readings, remaining completely unaffected by oval chainrings or erratic pedalling.
160-Hour Rechargeable Battery: Equipped with premium lithium-ion batteries that supply up to 160 hours of ride time per charge, topped up via magnetic USB-C connectors.
Advanced Cycling Dynamics: Delivers pro-grade performance data including Platform Centre Offset (PCO), Power Phase (PP), Torque Effectiveness (TE), and Pedal Smoothness (PS).

Look Keo Loyalists: The perfect upgrade if you love the traditional feel of Look road pedals but want direct, highly accurate power data without changing your cleat setup.
Set-and-Forget Calibration: Ideal if you want a fuss-free experience, as the smart auto-calibration algorithm continually adjusts itself without requiring manual zero-resets before every ride.
Data-Driven Athletes: Perfect for riders looking to fix muscle imbalances or smooth out their pedal stroke, thanks to advanced metrics like Platform Centre Offset and Power Phase.
Multi-Device Connectivity: Excellent if you simultaneously broadcast to a bike computer, a sports watch, and a virtual indoor training platform like Zwift via the triple Bluetooth channels.
Modular Investment: The smart modular architecture allows you to easily swap the internal power spindle into Favero's off-road MTB or Shimano SPD-SL pedal bodies down the track.
❌ Shimano Cleat Users: These pedals are strictly built around the Look Keo standard; if you are fully committed to Shimano SPD-SL road cleats, you will need to look at the Favero Pro RS-2 variant instead.
❌ Wall Plug Charging Needed: Unlike battery-operated units that swap out in seconds, you must remember to connect the proprietary magnetic charging cables to a power source periodically.
❌ Strict Warranty Procedure: In the rare event of a technical issue, Favero's official warranty troubleshooting requires opening a remote diagnostic digital support ticket directly with their European factory.
To ensure flawless performance and prevent any false data spikes, always install the included pedal spindle washers if your crank arms have recessed faces or protective clear skins. These washers prevent the internal sensor housing from binding or compressing against the aluminum face of the crank arm. When it comes to charging, don't wait for the low battery warning; because lithium-ion batteries thrive when kept topped up, use the extra-long dual magnetic USB-C cable to plug them in after every few weeks of heavy riding, keeping them ready for any last-minute weekend century!
