Assioma DUO Power Meter

The Favero Assioma DUO power meter is a double-sided pedal powermeter. The left and right leg are measured completely independently of each other. The left-right distribution and other parameters of the pedaling motion can be displayed directly on the bike computer. The Assioma DUO powermeter is based on the Look Keo system. It is also available in a single leg version, the Assioma UNO.

We are often asked about the version of the Assioma Duo Powermeter: We exclusively sell the updated 2022 version with black springs!

Highlights and Downsides

  • dual-sided power measurement with high accuracy (± 1%)
  • rechargeable battery (50h operating time)
  • integrated cadence measurement
  • IAV Cycling Dynamics
  • low weight (300g for both pedals)
  • excellent durability (low complaint rate)
  • spare parts available (easy replacement of bearings or pedal body)
  • plug 'n play and easy to switch between bikes
  • works with many bike computers and smartphones (ANT+ & Bluetooth)
  • can only be used with Look Keo compatible cleats (but there is also a version for SPD-SL)
  • in a crash, the bike usually lands on the pedal
  • with large cycling shoes shoe can touch the sensor (shims might help)

Dual-sided measurement

With the Assioma Duo, both pedals are equipped with measurement electronics. Therefore, power and force distribution can be measured individually for each leg. Especially in the case of muscular imbalances, you have a clear advantage with the dual-sided Assioma Duo. This makes the Duo particularly suitable for ambitious riders who want exact power readings and want to learn more about their pedaling technique.
For beginners and riders with a tight budget who can live without the last few percentages of accuracy, the single-sided Assioma Uno is a good alternative.

Compatible bike computers and smartphones

ANT+ capable bike computers (Garmin, Wahoo, O-Synce, Sigma, SRM, etc.) work without problems with the Assioma. Since the data transmission of the Assioma also takes place via Bluetooth Smart, the power meter can also be paired with smartphones.

Compatible bikes

The Assioma Duo power meter can generally be used with any bike (road bike, gravel bike, trekking bike, etc.). However, you should refrain from hard off-road use. You also need cycling shoes with a 3-hole standard in order to mount the Assioma cleats.


The cleats are based on the Look Keo standard. To be able to mount the cleats on the shoes, road shoes with 3-hole standard are required. Original Look Keo cleats can be used with the Assioma. However, we recommend the original Assioma cleats. In our experience, they last much longer and walking is more stable and comfortable with the Assioma cleats.

Rechargeable battery

The battery life of the Assioma Duo has been increased from 30 hours of it's predecessor bePRO up to 50 hours. To charge the batteries, the pedals remain mounted on the bike. The included charging cable is simply clicked on the pedal with a magnetic connector.

Construction and design

The profile of the power meter housing has been flattened to minimize the likelihood of the shoe coming into contact with the sensor. The goal in developing the Assioma was also to make it even more rugged and durable than the previous model. The powermeter is waterproof and dustproof.


The weight of the complete Assioma Duo power meter pedals is lower than many other pedals without a power meter - the set of Assioma pedals weighs less than 300g including the batteries!


We were able to confirm the excellent measurement accuracy of +-1% several times on our calibrated Cyclus II ergometer in the laboratory and in comparison with other power meters on the road.

Oval chainrings

The Assioma Duo can be used with oval chainrings without restriction. The measurement is not affected by errors caused by very irregular pedaling (e.g. uphill sprints) or oval chainrings. This is because Assioma can determine the actual instantaneous angular velocity throughout the pedal stroke, providing high accuracy under all conditions.

IAV Cycling Dynamics

With Cycling Dynamics you get an in-depth look at your pedaling technique. In addition to the obligatory power readings, the following data is also transmitted:

- Power Balance (left/right distribution)
- Cadence
- Torque Effectiveness (percentage of force on the pedal that is effective for propulsion)
- Pedal Smoothness (uniformity of force distribution during pedal stroke)
- Power Phase (part of the pedal stroke in which the most power is applied to the pedal)
- Rider Position (time spent sitting or standing)

Setup and firmware updates

A smartphone and the Assiom app (Android, IOS) are required for the initial setup and registration. The Assioma app is also required to install firmware updates. The settings of the powermeter (e.g. the crank length) can be conveniently made via a smartphone.


The installation is very simple - the Assioma pedals are simply screwed to the bike like normal pedals. A real plug 'n play power meter! The required tool (8mm Allen key) is included in the package. This also allows easy swapping between different bikes. In addition, the Assioma pedals can be taken on vacation or to a training camp and mounted on a rental bike.


The Assioma are rugged and sustainably constructed. They have the lowest complaint rate with our shop. The powermeters are modular and worn parts such as bearings or pedal bodies are easy to replace. In our experience, the Assioma are currently the best power meter pedals on the market.

Warranty and support

The Assioma Duo comes with a 2 year warranty. The pedals are produced by Favero in Italy. The Assioma are very reliable power meters. However, if there is ever a problem, Favero offers good and customer-oriented support. If the pedals are connected to the Assioma app, it is possible to start a remote fault diagnosis via the Internet and thus identify the problem. Often, a quick solution can be found without having to send in the pedals.

Assiomas in a crash

I had my pedals for 3 months and everything was great. Functionality is perfect. But 10 days ago I was hit by a car. I am relatively ok but I got some damages on my bike. Regarding Assiomas my right pedal is still functional but is severely scratched. The power meter part of the pedal is untouched and it’s a good thing the power meter is not in the axis. But the pedal is damaged. Even the metal plate which is the base for the cleat. The plastic of which the pedal is made is relatively soft. If I compare it with the Look Keo carbon blade pedals which I used before, Assiomas are much softer. Even my left pedal, where I can sometimes put my foot on the bottom part of the pedal while clipping, has marks. If Favero would reinforce the pedal with carbon and make it as strong as Look, it would be perfect. My Look pedals after 4 years look almost like new. Favero needs to improve the composition of the material to make them perfect.

Great service, and communication via email, which I really very much appreciated. Product worked straight out of the box - and this is why I went Favero instead of Garmin. Very happy with it. Five stars all around.

Review after 6 months and 8300~km

This is my opinion, drafted as a review, for the Favero Assioma Duo Power Meter pedal, which will include experience with post-sale support with the online shop, powermetershop, and with Favero.

First I'd like to point out that I am an amateur cyclist without any attachments to the aforementioned companies. I've paid and installed all equipment myself, for the full price retails.

TL, DR: I strongly recommend buying the Favero Assioma Duo power meter. Also, I strongly recommend buying them from the online shop powermetershop, especially due to their post-sale support. Moreover, I have to acknowledge the explendid support from Favero themselves in providing the necessary replacements for my particular problem, free of charge (inside warranty period).

I bought the Assioma Duo because I wanted to up my training, in the sense that I was hitting a plateau and needed further data to better structure more interesting training sessions. I saw this after using a Smar Trainer during winter, and missing the power readings once I got back on the road at Spring.

I have ridden about 8300km or so for the last 6 months with the Assiomas. They have never failed me, never have had output issues or low/up readings of power. Moreover, the battery on them is amazing! I had to charge once every 3-4 weeks, given that averaged about 13h/15h per week of training. It is easy and really intuitive to charge and to update the firmware through Favero's app.

About two weeks ago, I had an issue with my right pedal. The cleaping mechanism, which is made out of plastic, broke when I was unclipping on a stop sign during a ride. At first I thought it to be something related to my shoe, maybe some dirt stuck on the sole, but once I inspected the pedal I realized what had happened.

My first action was to contact with the online shop that I had bought the Assiomas, powermetershop
Their support team promptly replied to my request. I had enclosed pictures showing the damaged, in order to make my request more valid (obviously I did not want them to think I was scamming them).
They quickly forwarded my request directly to Favero's support, whom also responded quite rapidly (the back and forth took a single day).
Favero inquired for the situation in which the pedal had given in, not because they did not trust my problrm, but because they wanted a feedback on their product's reliability. I answered with similiar manner as to what I just described here, and they only requested the Pedal's IP number for their database. I should clarify thst each sensor (right and left) has an unique IP, therefore they could see all the data from that pedal once I gave the IP number.

Once they confirmed the IP, promptly send me a replacing pedal body for my right pedal, and also clearly gave me instructions as to the required tools and the steps to replace the body. It was really easy, and with some help from my Dad I could change them in about 10 minutes.
I have just tested the pedal, and it is working flawless.

All in all, I am extremely happy with Favero Assioma Duo's performance, measurement and realibility. I also highly recommend Favero as a brand, their support was incredible! And I strongly recommend shopping through powermetershop, which is a completely honourable shop and has fadt delivery/nk hassle.return (replacement) of orders as their priority.

Thank you powermetershop and Favero for all your support and attention on this matter. Here are the photos of the new right pedal body as proof of change.
