Product Description

Favero Assioma PRO RS-1 Watt Pedals - SPD-SL

Ultralight construction
Weighing just 123.5g per pedal (left with sensor) and 122.5g (right without sensor), the RS-1 is one of the lightest watt pedals on the market. Total weight: 246g.

Single-sided wattage measurement with ±1% accuracy
IAV Power technology ensures precise power measurement independent of cadence, oval chainrings and thread variation.

Advanced metrics and data collection
Measures both power and cadence via built-in sensor and gyroscope. Supports metrics such as Platform Center Offset (PCO), Power Phase, Pedal Smoothness and Torque Effectiveness.

Bluetooth and ANT+ connectivity
Compatible with most cycling computers and training apps, including Garmin, Wahoo, Zwift, TrainerRoad and Strava.

Long battery life and magnetic charging
Up to 60+ hours of battery life per charge. Charging is done via the included magnetic USB cable, which is both convenient and safe.

Build quality and durability
The pedal body is made of carbon fiber reinforced technopolymer with stainless steel plate and needle bearings. The podless PRO spindle ensures a closed and robust construction that is also easy to clean.
Waterproof: IP67.

Q factor and stack height
Q-factor: +53 mm. Stack height: 10.5 mm – provides optimal power transfer and pedaling economy.

Modular and upgradeable design
The pedal axle can be combined with both road and MTB pedal bodies, making it easy to upgrade or adapt as needed, without special tools.

Compatibility and installation
Fits all cranksets with standard 9/16” thread.
Compatible cleats: Shimano SPD-SL (SM-SH10, SM-SH11 and SM-SH12 – 3-bolt standard).
The pedals come with Shimano SPD-SL compatible cleats.

User experiences and lessons learned

The Favero Assioma series is recognized for its reliability, precision and ease of installation.
Several users highlight the long battery life, stable data, and user-friendly setup.
However, some riders find that clipping in may take some getting used to due to the pedal's low profile and different geometry.

Compared to other power meters (e.g. in cranks or hubs), wattage data from pedals will typically be slightly higher as they measure before driveline losses.

Favero watt pedals – precise data directly under your foot

In a sport where marginal gains and training optimization are everything, power meters are no longer reserved for the elite. They have become a natural part of the equipment of many ambitious cyclists and triathletes – and Favero power pedals in particular have become popular for their precision, reliability and ease of use. With the measurement directly in the pedal, you get data from the place where the power is actually transferred – and this means more accurate and realistic measurements compared to other locations such as the hub or crankset.

Favero has managed to combine high precision with a lightweight and robust design that is perfect for both everyday and competitive use. The Watt pedals are easy to install on your own, can be moved between bikes in minutes and are compatible with most systems and platforms. For triathletes and road riders who want to closely monitor their training and optimize every step, Favero is one of the most reliable choices on the market.

UNO or DUO – single-sided or double-sided measurement

One of the big questions when looking at watt pedals from Favero is whether to choose single-sided or double-sided measurement. The single-sided solution measures the power in one pedal and doubles the data, while the double-sided solution measures each foot individually and shows the real distribution. For most exercisers, a single-sided solution is enough – you get precise numbers and the ability to control your training by watts, FTP and intensity.

However, for the more dedicated triathlete or cyclist who wants insight into asymmetries, pedaling technique and muscular balance, double-sided measurement is worth its weight in gold. It can help identify weaknesses, improve technique and prevent injuries. Favero allows you to start with one pedal and later upgrade to two – this provides flexibility and makes it easy to adapt your setup as you develop as an athlete.

The pedals communicate seamlessly with most bike computers and training apps via both ANT+ and Bluetooth, making them ideal for both outdoor training and home training on smart trainers or virtual platforms like Zwift and TrainerRoad. The data is stable, and the battery lasts for many hours of riding - with easy charging via magnetic connector.

That's why watt pedals are indispensable for triathletes and cyclists

Training with power meters is no longer just for the pros – it’s a game-changer for anyone who wants to understand their training better and get more out of every hour in the saddle. Unlike heart rate, which can fluctuate depending on sleep, stress, temperature and caffeine intake, watts are an objective measure of the exact amount of work you’re putting in. This means you can plan, structure and analyse your training much more precisely.

For triathletes, wattage is especially useful on the bike portion, where pacing is crucial. By staying within a certain wattage zone, you can avoid going too hard and ensure you still have energy left for the race. In addition, wattage allows you to track your progress over time and see if your training is actually working – something that both motivates and builds confidence in the process.

Favero makes power measurement available in a form that is easy to use, accurate and affordable. The combination of low weight, precise measurements, long battery life and simple installation has made the pedals a staple for both exercisers and competitive athletes. And with the ability to remove the pedals and move them to another bike in minutes, it is a flexible system that fits perfectly into the everyday lives of many cyclists and tri-people.
