Favero Assioma UNO Power Meter Pedals

The Favero Assioma UNO Power Meter Pedals are the single-sided version of the Assioma DUO power meter with a power sensor located in the left pedal. The Assioma UNO works by doubling your left leg power in order to derive your total power. It is every bit as reliable and consistent as the DUO, and because it contains just the left pedal sensor, it is priced at only $459, making it the most affordable power meter pedal you can buy!

In addition, the UNO Power Meter Pedals have all of the features found in the DUO. You get ANT+ and Bluetooth SMART compatibility, a rechargeable battery with 50-hour life and of course Assioma’s +/- 1.0% accuracy levels. Yes, that’s right. Using Favero’s IAV Power Technology, the Assioma UNO is accurate to +/- 1.0%.

The new Assioma is also easy to install. In fact, it installs just like a normal pedal. Just grab an Allen key and screw it on. Easy as that!


Favero Assioma UNO Highlights

Accurate with IAV Power

The Assioma uses Favero’s IAV Power Technology. IAV results in accuracy of +/- 1.0% and allows the Assioma pedals to be used with oval chainrings without any impact to the accuracy of your 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 are compatible with your favorite cycling computer, GPS watch, smart phone or tablet. The choice is yours!


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

IAV Cycling Dynamics

Favero’s integrated 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!

Proved and Guaranteed

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

Favero IAV Power Technology

The Favero Assioma UNO uses Favero’s IAV (Instantaneous Angular Velocity) Power. Using special software and an integrated three-axis gyroscope, IAV takes into account the precise pedaling speed within each pedal stroke. This results in the Favero Assioma UNO 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. IAV Cycling Dynamics is compatible with the Garmin Edge 1030, 830, 820, 530 and 520 Plus.


Updated Spring Tension

Favero recently changed the spring in order to have a wider release torque tension and these pedals come with the new spring pre-installed. 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.



The Favero Assioma UNO comes supplied with red, 6-degree float cleats. You also have the option to purchase black, 0-degree (fixed) float cleats. If you have LOOK Kèo cleats, they will also be compatible with the pedals.

    I’ve put about 350 miles on this power meter. Installation was a breeze, Installation is super easy, like changing normal pedals. Using the app to connect the pedals to my phone was really easy and updating the firmware was simple. The charging cable was also easy to use. Paired up easy with my Garmin 510. I would recommend for the price.

      Hi. Thanks for the review. We are absolutely loving both the Assioma UNO and DUO and are glad you are too. It’s an amazing bit of technology for the price – accurate and really reliable. Favero did an amazing job with it.

    The Assioma UNO is a good power meter pedal. Easy to install including the app. Paired right up no problem with my Garmin 735 watch. Great readings for power and speed. The charge lasted about 5 rides and was easy to charge. The problem I had was unclipping. I’m a small, old female and could not clip out. PMC was supportive in helping resolve my issue. Kind and supportive.

      Hi Skiingsmith. Thank you for leaving us a review on your Assioma UNO. Both the DUO and UNO are quickly becoming two of our best-selling power meters – so I am glad you like it. However cleat engagement is indeed firm on them when compared to some other pedals, and we’re sorry if that was an issue. Please let us know if there is anything else we can do!

    I’ve had the Uno for almost a year and a half now. I use them for Zwift virtual racing and also outdoors on my road bike. I agree that cleat engagement is firm but otherwise these are a great product and I received excellent service from the folks at Power Meter City.

    I purchased the Assioma UNO. I’ve ridden about 500 miles with it. Zero problems. It was easy to get up an running with all my apps and bike computers. Zwift absolutely loves this power meter with my iPad. Just remember to put the pedal into single pedal mode (for the Uno or the Duo). One charge last weeks. The pedals will start flashing when they need a charge. Training with power is the final frontier. If you’re serious about getting better or just a stats nerd you must have power (or if want to use Zwift, Sufferfest. etc.) Takes all the guess work out of riding and training.

    Wonderful customer service. I called to ask questions and got more help on the phone than I expected. They were thorough and detail-oriented in explaining all my options and gave me good recommendations for what would work best for me.
    So far I’m really happy with the product, too. This is the first power meter I’ve owned so I can’t compare it to anything else (other than what I’ve used on a spin bike), but so far so good. It’s working well and it was easy to setup and install.

    Arrived in Dubai very quickly – impressive. Installation, both physical an electronic (with Garmin 820), was very simple. I love the magnetic charging adapter. I find too many things with micro-USB sockets don’t last very long because the socket loosens over time and then charging becomes difficult or impossible – a real issue with with PowerPod in my experience. Unlike a couple of other comments, I have not found the cleat/pedal engagement to be an issue, even straight out of the box with no adjustment. I feel them to be similar to the SPDL pedals and cleats I was using previously. It is also great, with cadence being measured by the pedal, to be able to dispense with my separate cadence device.

    Very happy with these pedals so far. Installation was very easy, and paired with my iphona and trainer (Wahoo kickr core) seamlessly. I highly recommend these pedals.

    So far so good. Install was easy and the pedal paired right up with my Garmin 520. I was previously using the 4iiii 105 Crank meter (which I also loved) but didn’t want to replace the crank and wanted something more portable for my new ride. As usual, the folks at PMC were very helpful.

    Easy to install. I could not get the meter to send data to my Garmin so I chatted online and got a fast and simple solution. Great product and great company.

    I’ve used these for about a month now and they are great! They work well, I don’t have any problem clipping in or out and they are super easy to calibrate. They give great feedback for training or race. Excellent price and shipping time as well, had them in my hands in 48 hours!

    These pedals are super accurate and amazingly easy to use. They’re very top notch and at a good price. The only thing I don’t like is that they spin so easily and sometimes that makes it a little harder to clip in at a traffic light, but once you get used to them, it’s not really a big deal. I wouldn’t let that stop anyone from grabbing these steals right away.

    A great deal for a solid power option. These were easy to install and calibrate. I agree with those who say they are tight when you get them but just adjust the tension and you are good. I also made the mistake of not changing the setting to read one pedal versus two so I thought I hadn’t calibrated them correctly. I went to my local shop and compared the pedals to a trainer and accuracy was right on. I love having such a simple and affordable option for power.

    I’ve only had the pedals for a week but excellent so far. Installation was quick and easy. Customer service was terrific from start to finish, even calling me personally to help ensure I could get the package through Canadian customs without paying any duties. Delivery was very fast considering the international shipping in this instance. The pedals feel firm (in a good way) and very secure. The various features (travel mode, performing a zero offset, pairing to Zwift and/or my watch, etc) are all functioning well. They read about 10 watts higher than my TACX smart trainer – I suspect this is a combination of small inaccuracies in both (1% on the pedals and 2% on the trainer), as well as the pedals accurately reading slightly higher power since they are the point of force application on the bike. Will re-review after 6 months to report in on how well they hold up over time. So far, very happy with my purchase.

    My first ever power meter, and I spent a ton of time researching–Power Meter City’s website/info/reviews were most helpful in narrowing down my decision. Thank you for laying out everything so clearly! Pedals were really very easy to install, and so far, they’re great! Grateful for an entry-level power meter that delivers the goods but doesn’t break the bank (as much). And thank you, Power Meter City, for making this a less-daunting process.
