Favero Assioma DUO Power Meter Pedals

Favero introduced their first power meter, the bePRO, in 2015. It was a hit among cyclists of all levels due to its accuracy, reliability and low price point. Favero is at it again, this time with the Favero Assioma DUO Power Meter Pedals. Like the previous version, the Favero Assioma power meter pedals are a dual-sided power meter with a power sensor located on each pedal. This means the power meter can show both left and right power, in addition to total power and cadence.

However, Favero made several big changes with the Assioma. To begin with, it now installs like a normal pedal. No special tools or set-up steps needed. Just use the supplied Allen key and screw them on. In addition, the Favero Assioma pedals now have both ANT+ and Bluetooth SMART. The power meter kept its rechargeable battery, but now has 50 hours of battery life.

Accuracy was also improved. The Assioma uses Favero’s IAV Power Technology. IAV takes into account the precise pedaling speed within each pedal stroke, resulting in accuracy of +/- 1.0%.


Favero Assioma DUO Highlights

Dual-Sided Power

With a power sensor on each pedal, the Assioma can measure true left and right power. While some power meters provide an estimated left/right power figure, only a few can provide true left/right data.

Easy to Install & Transfer

Installing a power meter doesn’t get any easier. Grab the Allen key, screw on the pedals and you’re ready to go. This means you can also move them from bike to bike in seconds!

ANT+ & Bluetooth SMART

With both ANT+ and Bluetooth SMART, the pedals will work with your favorite cycling computer, GPS watch, smart phone or tablet. The choice is yours!

Accurate with IAV Power

The Assioma uses Favero’s IAV Power Technology. IAV results in accuracy of +/- 1.0%. It also allows the Assioma pedals to be used with oval chainrings without any impact to the accuracy of your data!

IAV Cycling Dynamics

Favero’s built-in gyroscope also allows you to measure cycling dynamics data such as IAV Power Phase and IAV Rider Position. With these advanced metrics, you can become a faster, stronger rider!


Using cutting-edge materials, the weight of each pedal is only 149.5 grams. This makes it the lightest power meter pedal available.


The Favero Assioma uses a rechargeable lithium-ion battery which offers a 50-hour life. When the battery gets low, simply plug them in using the included charger, and you’re good to go again.

User Friendly App

The Assioma app allows you to update firmware, perform zero-offsets, check battery levels and more. Also, the “Compatibility with other apps” function ensures it works with other apps and training software.

Proved and Guaranteed

Each Assioma undergoes strict control tests (load, shock, fatigue, wear, water resistance, etc.) in order to ensure performance. It also comes with a full two-year warranty.

Favero IAV Power TechnologyFavero Assioma IAV Power Graph

The Assioma uses Favero’s IAV (Instantaneous Angular Velocity) Power. Using special software and a built-in three-axis gyroscope, IAV takes into account the precise pedaling speed within each pedal stroke. This results in the Favero Assioma DUO having accuracy of +/- 1.0%. In addition, IAV allows you to use the Assioma pedals with oval chainrings without any impact to the accuracy of your data!


Favero IAV Cycling DynamicsFavero Assioma IAV Cycling Dynamics

Favero’s gyroscope also allows you to measure cycling dynamics data. IAV Power Phase displays the portion of your pedaling stroke in which torque is produced. In addition, your Power Phase Peak, in which maximum torque is produced, is also indicated. IAV Rider Position displays the portion of time you are in a seated vs. standing position. This allows you to analyze how a specific position can influence your performance. This data works with most Garmin bike computers including the Edge 1030, 830, 820, 530 and 520 Plus.


Now with Auto-Zero!

The pedals now have auto-zero. With this feature, the power meter will perform an automatic zero-offset (calibration) every time you ride, which helps ensure the power meter stays accurate!


Updated Spring Tension

Favero changed the spring in order to have a wider release torque tension and these pedals come with the new spring. The new spring’s release torque tension has been lowered from 11Nm to 8Nm. Therefore, the pedals are now easier to clip in and out of.


Favero Assioma DUO Pedal Cleats

The Favero Assioma DUO Power Meter Pedals come supplied with red, 6-degree float cleats. You also have the option to purchase black, 0-degree (fixed) float cleats.


Bike: The Favero Assioma power meter pedal is compatible with any road or indoor bike.

Cleats: The power meter uses a LOOK Keo style 3-bolt road cleat. One set (red 6-degree float) comes supplied with the power meter.

We also offer LOOK Keo Road Cleats as well as LOOK Keo Grip Road Cleats which may be used with the power meter. The Grip version costs slightly more, but includes a non-slip surface, which makes walking easier and safer. Please note, the Grip version isn’t officially recommended by Favero and some customers report they change the feel of the pedals slightly. Please take this into account if you opt for the Grip version of the cleats.

    I’m just beginning to use the pedals, they’re easy to install, easy to configure and connect with the cycling computer… I’m a beginner in power meter using and its data, but I felt they work well and I will keep working out with then and analyzing the data in order to achieve my goals as much as possible this gadget.

    • Power Meter City

      Let’s go get that power, Federico! Thank you for leaving us a great review. We hope you will continue to enjoy your DUO’s and if there is anything else we can help you with, please let us know!

  2. Pablo (verified owner)

    Great product. Works perfectly and definitely the best option if you ride different bikes. Power Meter City is a great place to shop.

    • Power Meter City

      Thank you, Pablo – we really appreciate this! If there is anything else we can do, please let us know! Ride safe!

  3. John (verified owner)

    Great purchase and extremely fast delivery…from California to Georgia in three days. The entire experience has been flawless. The pedals were easy to install and I’m looking forward to learning what the data tells me regarding my training.

    • Power Meter City

      Good luck on your future rides, John! Glad you liked your new DUO’s. Please let us know if there is anything else we can help you with!

  4. Alan Delaney (verified owner)

    I waited until I logged several hundred miles on the pedals before writing a review.
    Setup is super easy using the app and the supplied Allen Key, charge them up and off you go.
    As a PM the data seems as accurate as my DZero’s (looking at similar rides in TP), the pedals connect instantly to my computer and I have had no drops or issues during any of my rides.
    They are also a great pedal platform which was the aspect of the pedal that I was most concerned about but it was a seamless transition to the Favero Duo’s from my Shimano SPD-SLs.
    Excellent pedals and a shout out to Power Meter City for the super fast shipping.

    • Power Meter City

      Hi Alan, thank you for this amazing review! Looks like you are enjoying your new pedals! If there is anything else we can do, please let us know!

  5. Leslie Bristol (verified owner)

    Bought these after buying the Duo-Shi and these were closer to my fit. Either or they were both great products as seen by all the reviews. I purchased from Power Meter City and received both pedal sets on the same week to Hawaii. Fastest shipping ever!! Loved both products and will definitely buy all my power meter products from PMC. Thank you!

    • Power Meter City

      Looks like you are enjoying them, Leslie! Thank you for this kind review! We are here if there is anything else we can do! Thank you!

  6. ho (verified owner)

    just got these for my new bike. they are the best around!! i will consider getting another set.

    • Power Meter City

      Awesome! Thank you for this – we really appreciate it! Let us know if there is anything else we can do! Ride safe!

  7. David Conover (verified owner)

    I purchased and installed DUOs on my QR PRfive and have raced and trained with them for over a year (triathlon). The DUOs are fantastic. Great data and responsiveness – surely power and the other data provided are much more important to training and improving performance than average speed and cycling time. I am constantly improving my cycling (with the help of a great tri coach) thanks to the DUOs. Easy to install, connect to my Garmin Forerunner, check out on the app, calibrate, etc. etc. Wonderful product BUT equally if not more important is customer service. If a product is rated as ‘infinity’ and customer service as ‘zero’ then P x CS = 0. Customer service is top notch as well. Could not be happier even at 72 years of age and still doing tris.

    • Power Meter City

      Good job, David – keep it up! We hope you will continue to enjoy your new DUO’s. Please let us know if there is anything else we can do! Ride safe!

  8. Steve T (verified owner)

    I researched power meters for a few years after using a one sided crank based unit for several years and wondering if it was accurate. Assioma seems to get the best reviews. Now using duos and enjoying the accuracy and peace of mind. I went with pedal based because they are accurate, easy to install and I can take them with me on vacations and use with rental bikes. Very satisfied. Planning to buy a spider pm for my gravel bike and will buy from PMC again. Great purchase experience!

    • Power Meter City

      Agreed! You found the right one, Steve! Thank you so much for this amazing review! We hope you will continue to enjoy them and if there is anything else we can do, please let us know! Ride safe!

  9. Steve Martino (verified owner)

    Great pedals, easy set-up and reasonable price for dual power meters and I get lots of great data from them. The data is changing my training and improving my conditioning. I’ve had them for over a year and they’ve preformed great. Charge lasts a long time, easy to charge when needed — never worry when I go on a trip. Overall very satisfied.

    • Power Meter City

      Thank you so much, Steve! These pedals are really amazing! If there is anything else we can do, please let us know!

  10. Travis

    The Assioma’s just work. That’s the most important aspect about them. No complicated setup, no issues in connection drops, reliability, battery life, funny numbers. No batteries to buy and install since they are rechargeable. I have had them for about four years, and until now each charge gives around 50-60 hours of riding time.

    Anyone who has multiple bikes or travels often, including without a bike, should be considering a pedal based option like these. I had crank based power before the Assiomas, and talking to TSA about the 7 inch piece of metal in your carry on can take time! With these, I travel with pedals and shoes and can easily install them on any rental bike or gym bike and get the same power data I’m used to training with. At home, switching between bikes takes less than a minute, though I have considered getting multiple sets.

      Wow! Thank you for this amazing review on your DUO’s! Looks like you are enjoying them! Please let us know if there is anything else we can do! Ride safe!
