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, 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, you can use the pedals 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 a built-in 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. Therefore, you can see how a specific position can influence your performance. IAV Cycling Dynamics works 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. 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.


Now with Auto-Zero

With the release of firmware version 4.75, the Assioma pedals now have auto-zero built in. With this feature, the pedals will calibrate on their own – no need to manually do it on your bike computer before your ride. This saves you time and ensures your power data is always accurate!


Favero Assioma UNO Pedal Cleats

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 KEO cleats, they will also be compatible with the pedals.


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. You may also use LOOK Keo original cleats with the power meter. In addition, the LOOK Keo Grip cleat (sold by us separately), features a non-slip surface, which makes walking easier and safer.

    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!

    • Power Meter City

      Hi Travis. Thanks for the review on your UNOs! Keep up the good work and let us know if you need anything else!

  2. Jon Judge (verified owner)

    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.

    • Power Meter City

      Hi Jon. Thanks for the review and I’m glad we could get things figured out for you! Please let us know if you need anything else.

  3. Steve (verified owner)

    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.

    • Power Meter City

      Hi Steve. Thanks for the note on your Assioma UNO. It’s a great pedal and we hope you continue to enjoy it. Please let us know if you need anything else!

  4. Juan Marin (verified owner)

    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.

    • Power Meter City

      Hi Juan. Thanks for the review. We’re glad to hear you are enjoying your UNOs!

  5. David Connolly (verified owner)

    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.

    • Power Meter City

      Hi David. Thanks for a great review on your UNOs! I’m glad to hear they are working out for you. Please let us know if there is anything else we can help you with!

  6. Jessica (verified owner)

    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.

    • Power Meter City

      Hi Jessica. It was our pleasure helping you out. We hope you continue to enjoy your Assioma UNO – it’s a great pedal at a nice price!

  7. GPPassion (verified owner)

    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.

    • Power Meter City

      Hi GPPassion. Thanks for a great review. Glad to hear you’re enjoying the Assioma – truly a great pedal – both indoors and out. Let us know if there is anything else we can help you with!

  8. MarkDK (verified owner)

    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.

    • Power Meter City

      Hi Mark. Glad you are enjoying your Assioma UNO and thank you for letting us help you out!

  9. skiingsmith (verified owner)

    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.

    • Power Meter City

      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!

  10. JY4913 (verified owner)

    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.

    • Power Meter City

      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.
