Favero Assioma Pro RS-1 Pedals with Power Meter

Assioma PRO RS is the lightest pedal power meter available for road bikes, weighing only 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 interruptions (power dropouts).
The spindle, which contains and protects all electronic components and the battery, is completely sealed and independent from the pedal body. This “separate elements” approach makes the product durable and very easy to maintain. Its sleek design, with a q-factor of only +53 mm and a stack height of 10.5 mm, makes it the perfect ally to improve your performance and achieve 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 reading available, with a rich range of advanced metrics. The modular design allows swapping pedal bodies between road and MTB while keeping the same spindle.

Simplify your training
It installs in seconds, just like a traditional pedal. Assioma PRO RS offers auto-calibration functionality and immediate connectivity via Bluetooth and ANT+ for smooth, worry-free rides.

An extraordinary pedal
Easily move it from one bike to another and pair it with your favorite devices: bike computers, smartwatches, or apps like TrainerRoad, Zwift, Rouvy, and many more. Monitor your power data simply on any paved road.

Innovation at the 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 unmatched durability and long-term performance. The absence of electrical contacts, typical of replaceable batteries, eliminates the risk of power dropouts.
The absence of power ports or openable battery compartments eliminates the risk of water infiltration, allowing the product to offer IP67 protection rating throughout its lifespan. Reliability guaranteed even in the most extreme conditions.

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

Take every corner with confidence
Experience a total connection with your bike. Assioma PRO RS weighs only 123.5g per pedal, uses a pedal body made of carbon fiber reinforced technopolymer with a large stainless steel contact surface and high-quality roller bearings for unparalleled stability.

From road to MTB in minutes
Want to switch from road bike to MTB and vice versa? With Assioma PRO you can use a single axle and change the pedal body as needed. In just a few simple steps and without emptying your wallet!
No adapters or special tools needed, and you’re ready to go.

Every single ride measured with precision
Power and cadence are fundamental, but why stop there? Thanks to PCO, Power Phase, Seated/Standing Position, TE, PS, Left/Right balance, and much more, you get an in-depth reading to perfect every pedal stroke and surpass your limits.
Unlock your full potential with accurate, reliable, and consistent power data in any weather condition. No margin of error, just precise analysis to boost your performance. Pair Assioma PRO with your favorite 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 pedaling dynamics. By analyzing force distribution on the pedal, it helps identify inefficiencies, incorrect cleat positioning, and muscle imbalances.
More than just a watt reading: PCO allows you to refine technique, adjust cleat position, and potentially prevent injuries.

Precision in every condition
Thanks to IAV Power technology, Assioma PRO RS measures real power even during explosive sprints, high-cadence pedaling, or with the use of oval chainrings, ensuring unprecedented accuracy on Shimano® compatible pedals.

A technology that sets the standard
Powered by a three-axis gyroscope, the IAV Power system accounts for any pedal stroke variation for unmatched accuracy. Because you deserve a power data reading precise to ±1% and repeatable on every ride and in any condition.

Power always at hand
Rechargeable batteries are not only convenient but especially avoid those problematic power drops typical of disposable batteries. The magnetic charging system allows charging both pedals simultaneously, offering over 60 hours of autonomy with a single charge.
On the move? No problem. You can recharge Assioma PRO RS anywhere with a regular power bank, whether at home or on the road.
