Built for Cyclists Who Want Precision Without Extra Weight
One of the most impressive things about the Favero Assioma PRO RS-1 is how light it is. Favero describes it as the lightest road power meter pedal available, weighing only 123.5 g for the left pedal with power sensor and 122.5 g for the right pedal without power sensor.
That low weight matters for performance-focused cyclists who want every component on the bike to contribute to efficiency. Combined with a sleek profile, low stack height, and optimized q-factor, the RS-1 is built to feel natural underfoot while giving you the data you need to improve your training.
Single-Sided Power Measurement for Smart, Effective Training
The Assioma PRO RS-1 is a single-sided power meter pedal system, meaning the left pedal contains the power sensor while the right pedal does not. This setup offers a more accessible way to start training with power while still giving riders high-quality performance data.
For many road cyclists, single-sided measurement provides an excellent balance of performance, usability, and value. It allows riders to monitor output, cadence, and other advanced metrics while keeping the system lightweight and straightforward.
100% Shimano SPD-SL Cleat Compatibility
The RS-1 is designed for 100% Shimano SPD-SL cleat compatibility, making it easy for road cyclists to integrate into an existing setup. It is compatible with:
- Provided cleats (art. 773-20-64)
- Shimano SM-SH10
- Shimano SM-SH11
- Shimano SM-SH12
For riders already using Shimano SPD-SL style cleats, this compatibility makes transitioning to the Assioma PRO RS-1 far easier and more convenient.
Accurate Power Data with IAV Power System 📊
Precision matters when training with power, and the Favero Assioma PRO RS-1 delivers ±1% power accuracy, even with oval chainrings. That level of consistency helps riders trust the numbers they see and make better-informed training decisions.
This accuracy is powered by Favero’s IAV (Instantaneous Angular Velocity-based) Power System, which is engineered to provide reliable data in real riding conditions. For cyclists who are working on structured training, pacing, or performance improvement, accurate data can make a major difference.
Advanced Cycling Metrics for Better Performance Insights
The Assioma PRO RS-1 provides more than basic power readings. It offers a rich set of advanced cycling metrics, helping riders better understand their pedaling efficiency and overall performance.
Data visible via ANT+ or on the Favero Assioma App includes:
- Power
- Cadence
- PCO
- Power Phase (PP)
- Pedal Smoothness (PS)
- Torque Effectiveness (TE)
-
Rider Position (not available on the Favero Assioma App)
Data visible via Bluetooth includes:
The inclusion of PCO and other advanced metrics gives serious cyclists more tools to analyze their ride and identify areas for improvement.
Sealed Split Design for Durability and Easy Maintenance
A major design strength of the Assioma PRO RS-1 is its split approach. The power spindle, which houses the important electronic components and battery, is completely sealed and independent from the pedal body.
This design provides two major benefits:
- Durability
- Ease of maintenance
By separating the power sensor system from the pedal body, Favero has created a design that is both robust and easy to service over time. This is an important advantage for riders who log serious miles and want equipment they can depend on.
60+ Hours of Rechargeable Battery Life 🔋
Battery life is another strong point for the Assioma PRO RS-1. The built-in rechargeable lithium-ion battery delivers at least 60 hours of use per charge, helping riders spend more time training and less time worrying about power management.
Favero also emphasizes that the system operates with no power dropouts, helping ensure a stable training experience from start to finish.
Sleek Design for Road Performance
The Assioma PRO RS-1 is built with road riders in mind, and its dimensions reflect that focus. It features:
-
Low stack height: 10.5 mm
-
Low q-factor: +53 mm
These characteristics help create a more efficient and natural pedaling position. A lower stack height can improve pedaling feel and connection to the bike, while the low q-factor supports a road-oriented fit that many performance riders prefer.
Carbon-Fibre Tech-Polymer Pedal Body
The pedal body is made from carbon-fibre tech-polymers, giving the RS-1 a strong balance of low weight and durability. This material choice supports the pedal’s premium performance focus while helping keep total weight impressively low.
Modular Design for Added Flexibility
The modular design of the Assioma PRO RS platform gives cyclists added versatility. Riders can switch between road and MTB pedal bodies while keeping the same power sensor.
That makes the platform especially appealing to cyclists who value long-term flexibility and want a system designed with adaptability in mind.
Made in Italy 🇮🇹
The Favero Assioma PRO RS-1 is Made in Italy, which adds another level of appeal for riders who value thoughtful engineering and premium manufacturing standards.
