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.

    So here’s the deal… I am totally new to power meters. For that matter, I’m totally new to the triathlon sport as well. To add to my dilemma I am about as technically savvy as a rock! That being said I have found these pedals to be easy to install. And after some help from Josh over a couple of phone calls I have been able to navigate my way through the calibration process, which is very easy. I was able to check the calibration at a local shop and between their power trainer and the pedals both were nearly identical. I’d leave the difference to when I read my read out and the tech his. The last two perks are these are less expensive than others on the market and that they are easily transferred to other bikes.

      Thanks for the great review. I’m glad we could help you with your new Assioma DUOs and I’m sure you’re quickly becoming an expert. I hope you enjoy them and we are here if there is anything else we can do.

    These pedals are awesome! I bought them about 3 months ago and have put 1000+ miles on them with almost zero issues. Connected them to my Garmin and the sync has worked beautifully.

    Here are the best features about this meter in my opinion:
    -Easy installation (took me around 10 minutes and very easy to move from bike to bike)
    -Reliable ANT+ connection (have not experienced any “drop-out” yet)
    -Double sided power
    -Long lasting charge (have not even had to charge them yet)
    -Pedals light up so you know they are on

    Here is the one and only con:
    -Cleats do not buckle into the meter very well

    • Power Meter City

      Hi George. Thanks for the review on your Assioma DUO and the pros and cons list! 🙂 We’ve been using these pedals here since they came out and they are pretty much flawless. The cleat engagement and take some getting used to at first but they get a bit easier with time.

  3. Chris Van Andel (verified owner)

    I got these pedals about a month ago after doing a lot of research on powermeter pedals. They seemed to be the most convenient to set up, reasonably accurate, durable, and well designed. All of my expectations have been met. One of the best parts is that you don’t have to jump through hoops to move them from one bike to another. Unscrew them from one bike, put them on another one, tighten them up and do a quick zero calibration. No special angles or lock nuts, no external pods. No clearance issues. They paired easily with my Garmin 520, and the additional balance and efficiency data they provide has already led to an improvement in my pedaling technique after just a few weeks. I have about 200 miles on them so far, and I am still on the first charge.

    While this is not a trivial purchase, I would definitely buy them again in a second if I had a do-over. Well worth it.

    • Power Meter City

      Hi Chris. Thanks for the great review of your Assioma pedals. Sounds like they’re treating you nicely and glad to see you’re putting them to good use. Keep it up! We’re here if you need anything else.

  4. Yiannis.K (verified owner)

    Purchased the Assioma DUO pedals in the beginning of October and have done 1000km+ so far. Service from Power Meter City is top notch, responded to my queries and kept me updated with shipping dates. Had to pay import tax into the UK, but that wasn’t a showstopper (although quite a bit of money).

    Installation is very easy, as is swapping them between bikes. I have traveled with them, used them in temperatures ranging from 0 to about 30’C (UK, Greece, Majorca) with no problems so far. The battery life was one of my concerns, however I have only charged them twice so far, so the battery is definitely not an issue. Even after a flight the battery was ok (not drained, not on all the time). Also, the battery level on the Assioma DUOs can be checked via the mobile app.

    The only minor issue are the cleats. The ones that come with the powermeter are slippery. I would say it there was a place to keep costs down for Favero, that was the one. The cleats can be easily replaced with ‘Look’ branded ones. Very happy since then, no issues at all. Small bit of advice, as I am a little bit of a cleat destroyer myself, use the Look cleat covers and they will last for ages!

    I am very happy with this powermeter so far, and it has giving a great boost to my training!

    • Power Meter City

      Hi Yiannis. Thank you for the great review. We really appreciate customer feedback like as it provides additional insight for the rest of our customers. Additionally, I’m glad you are enjoying them. Favero did a great job with the Assiomas!

  5. Ivan Murdock (verified owner)

    Just a long term review – now over 2500 miles – never had an issue with them connecting, not a single spike and accurate repeatable.

    • Power Meter City

      Hi Ivan. Thanks for the updated review on your Assioma DUO. Glad they are working out! Let us know if you need anything else from us.

  6. Gina Sardi

    Ive had these pedals since Sept and they are great. I have about 900 miles on them and Ive charged them maybe twice. They’re great weight and of great quality, they preform just as well as my previous Ultegra pedal’s. The charging port is a great design thats super easy. The only down side I would say is the cleats took some getting used to, partly do to any cleat change, but they’re not as good as the Keo grip cleats. Customer service was great in helping me with pre-order and shipping. They were definitely worth the wait!

    • Power Meter City

      Hi Gina. Thank you for the review! We’re happy to hear you’re enjoying your new Assioma DUO pedals. They make training with power really easy…and who doesn’t want that! Let us know if there is anything else we can help you with!

  7. drsnuggels (verified owner)

    Finally i had the first two rides with the Assioma DUO.

    -Installation is super easy, like changing normal pedals.
    -magnetic connections for charging work very well
    -the first activation of the pedals via smartphone app is quick and easy
    -the smartphone app also shows the battery status per pedal
    -Pairing with Garmin Edge1000 works without problems

    The Assioma perform their work totally unobtrusive as it should be. Pedal works from the mechanics top and the data transfer entirely without failures.
    Better than the Vector 2 which i used before!

    • Power Meter City

      Hi Steffen. Thank you for the review. This is what we are hearing from other customers as well on the Assioma DUO. Not to mention the price is really good too! I think the folks at Favero really nailed it with this one. I hope you enjoy it and please let us know if there is anything else we can do!

  8. jameskrizan (verified owner)

    These pedals are easy to install and use. I’ve had them for over 500 miles and they work perfectly. In my opinion, these are clearly the best power pedals currently on the market.

    • Power Meter City

      Hi James. Thank you for the review. We’re getting lots of awesome feedback on the Assiomas and the price point sure makes them tough to beat 🙂 Let us know if there is anything else we can help you with!

  9. Ivan Murdock (verified owner)

    I have about 300 miles on them – accurate, repeatable, ease of installation.

    • Power Meter City
