Favero Assioma Pro RS-1 Power Meter Pedals

Assioma PRO RS is the lightest road bike pedal power meter available, weighing just 123.5 g per side. Compatible with Shimano® SPD-SL® cleats, it offers professional-level performance and over 60 hours of use per charge, without power dropouts.
The spindle, which houses and protects all the electronics and the battery, is fully sealed and independent of the pedal body. This separate-component approach makes the product durable and very easy to service. Its elegant design, with a Q-factor of just +53 mm and a stack height of 10.5 mm, makes it the perfect partner for improving your performance and achieving results in road training. The Assioma PRO RS power meter offers ±1% accuracy thanks to the IAV Power system, and provides the most comprehensive power readings available, with a wide range of advanced metrics. The modular design allows you to swap between road and MTB pedal bodies while retaining the same spindle.

Simplify your training
It installs in seconds, just like a traditional pedal. Assioma PRO RS offers automatic calibration and instant connectivity via Bluetooth and ANT+ for smooth, carefree rides.

An exceptional pedal
Move it easily from one bike to another and pair it with your favourite devices: bike computers, smartwatches or apps such as TrainerRoad, Zwift, Rouvy and many more. Easily monitor your power data on any paved road.

Innovation at its core
What makes it unique? It is the only power meter with electronics, strain gauges and a rechargeable battery fully protected inside a compact spindle, for unrivalled durability and long-term performance. The absence of electrical contacts, typical of replaceable batteries, eliminates the risk of power dropouts.
The absence of charging ports or battery compartments that open eliminates the risk of water ingress, allowing it to maintain its IP67 protection rating throughout the product's lifetime. Guaranteed reliability even in the most extreme conditions.

Maximum efficiency, no wasted power
Make the most of your cycling potential with the 100% SPD-SL®-compatible power meter pedal. Precise engagement and release and a wide range of release tension adjustment, all in one system without the limitations of leaf-spring pedals. With a stack height of 10.5 mm for optimal power transfer and a standard Q-factor of 53 mm for tackling the tightest corners, Assioma PRO RS is synonymous with performance.

Take every corner with confidence
Experience a complete connection with your bike. Assioma PRO RS weighs just 123.5g per pedal and uses a carbon fibre-reinforced technopolymer pedal body with a large stainless steel contact surface and high-quality needle bearings for unparalleled stability.

From road to MTB in minutes
Want to switch from your road bike to your MTB and back again? With Assioma PRO, you can use a single spindle and change the pedal body as needed. In just a few simple steps, without breaking the bank!
No adapters or special tools needed, and you are ready to go.

Every ride measured precisely
Power and cadence are essential, but why stop there? With PCO, Power Phase, seated/standing position, TE, PS, left/right balance and much more, you get detailed insights to refine every pedal stroke and push your limits.
Unlock your full potential with accurate, reliable and consistent power data in all weather conditions. No margin for error, just precise analysis to improve your performance. Pair Assioma PRO with your favourite devices and build your ideal training setup.

PCO: the metric that makes the difference
One of the few power meters on the market to offer PCO (Platform Centre Offset), Assioma PRO RS reveals hidden asymmetries in your pedalling dynamics. By analysing how force is distributed across the pedal, it helps identify inefficiencies, incorrect cleat positioning and muscle imbalances.
More than just a wattage reading: PCO allows you to refine your technique, adjust your cleat position and potentially prevent injuries.

Accuracy in every condition
Thanks to IAV Power technology, Assioma PRO RS measures actual power even during explosive sprints, high-cadence pedalling or when using oval chainrings, ensuring unprecedented accuracy for Shimano®-compatible pedals.

Technology that sets the standard
Powered by a three-axis gyroscope, the IAV Power system takes every variation in your pedal stroke into account for unrivalled accuracy. Because you deserve power readings accurate to ±1% and repeatable on every ride, in any condition.

Power always at hand
Rechargeable batteries are convenient and, above all, prevent the troublesome power dropouts typical of disposable batteries. The magnetic charging system allows you to charge both pedals simultaneously, providing over 60 hours of battery life on a single charge.
On the move? No problem. You can charge Assioma PRO RS anywhere with a standard power bank, whether you are at home or travelling.
