FAQs

You have to calibrate the pedals at first and every new installation but you don't need to calibrate them before every ride since the automatic calibration feature will take care of it for you.

Automatic calibration will happen without you even realizing: the only suggestion is to store the bike upright (not tilted), with no loads applied to the pedals. The position of the crank arms is irrelevant.

You can still perform manual calibration before your rides if you wish to, but it's not necessary at all. In this case, the values recorded by the last automatic calibration will be simply overwritten.

When it is installed for the first time (and every time it is mounted on a new bike), it is necessary for Assioma to carry out an internal self-calibration to be able to transmit the power data. Self-calibration occurs by performing a few dozen pedal strokes, while sitting and in a uniform manner. We therefore recommend pedaling on flat terrain for it to correctly happen.

You can disable the calibration option on your bike computer, as with the Assioma's auto-calibration functionality it's not necessary.

Remember, though, to perform manual calibration at first and every new installation.

Unfortunately no, you can't. Even though they might look alike, the spindle with sensor of Assioma DUO-Shi undergoes a different factory calibration and has a slightly different design with an oil retainer glued to the spindle.

Yes, you can! Both models share the same spindle, making them ideal for a pedal swap. The process is straightforward as there’s no need for special tools. This is because all critical components, such as the strain gauges, electronics, and rechargeable battery, are securely housed inside the spindle. 

For a step-by-step guide, you can follow the detailed infographic available in our app under the 'Support' section.

The pedal bodies compatible with Assioma DUO-Shi are Shimano® PD-R8000, PD-R7000, PD-6800, PD-R550, and PD-R540.

These are not sold together with the product to offer our customers the best value for money.

So far, the IAV Cycling Dynamics have only been implemented by Garmin on a limited amount of devices. Make sure yours is one of the list:

Edge Cycling Computers

• Edge 520 Plus

• Edge 530

• Edge 540 Series

• Edge 820

• Edge 830

• Edge 840 Series

• Edge 1030 Series

• Edge 1040 Series

• Edge Explore 21 (not in real time)

To enable the IAV Cycling Dynamics, pair your Assioma sensors to your Garmin device via ANT+ exclusively. Click on "sensors", "sensor details" and enable the IAV cycling dynamics option.

It's important that the connection happens via ANT+, not BLE, otherwise, IAV Cycling Dynamics won't be displayed.

Should you not be able to find them, you're most likely connected via BLE. Please follow these steps to change to the ANT+ channel:

• Unpair Assioma from any surrounding devices and delete the sensors if previously saved in your head unit
• Pair the pedals to the Favero Assioma app to keep the Bluetooth channel busy
• With the pedals connected to the app, connect now the left sensor to your head unit. It is not necessary to pair the right pedal: it will be automatically found.

Assioma uses rechargeable lithium-polymer batteries.

Our products shift from a minimum of 50 operating hours with the Assioma UNO/DUO/DUO-Shi models, to a minimum of 60 operating hours with the Assioma PRO line. 

Only after 500 complete charge-discharge cycles (that is 25.000 hrs of training!), Assioma could lose up to 20% of its initial battery life. 

A low battery warning will be displayed on your bike computer when you still have 8 operating hours.

You can charge the pedals with the included magnetic charger and, when you're not at home, with any common power bank.
 

Setting the crank arm length on the Favero Assioma app is useful only when this parameter cannot be changed directly on your bike computer.
In fact, if your bike computer already provides this option, the value set through the app would be overwritten.

Assioma PRO must not be used with pedal extenders, crank shorteners, or any accessories that alter the crank arm setup, as they may cause damage. However, crank arm protectors are an exception and can be used without issue.

For optimal radio communication, the plastic end of the spindle (threaded side), which houses the LED and antenna, must extend at least 1 mm beyond the crank arm thread, making crank arms thicker than 15 mm in the threaded area unsuitable.

This requirement cannot be met in crank arms without a pass-through hole, as obstruction would hinder signal transmission.

Assioma provides several useful training data, yet its display largely depends on the transmission channel (Bluetooth or ANT+) your bike computer/app is using.

The data you can get with Assioma UNO/DUO and DUO-Shi is the following.

Via Bluetooth:

• Cadence

• Power

• L/R Balance (double-sided version only)

Via ANT+:

• Cadence

• Power

• L/R Balance (double-sided version only)

• Power Phase (PP)

• Rider Position (RP)

• Torque Effectiveness (TE)

• Pedal Smoothness (PS)

Assioma PRO models offer power data that can be seen both on your bike computer/app and in the "LIVE" screen of the Favero Assioma app.

Via Bluetooth:

• Cadence

• Power

• L/R Balance (double-sided version only)

Via ANT+ or Favero Assioma app:

• Cadence

• Power

• L/R Balance (double-sided version only)

• PCO

• Power Phase (PP)

• Rider Position (RP) – no Favero Assioma app

• Torque Effectiveness (TE)

• Pedal Smoothness (PS)

You can calibrate the pedals directly on the Favero Assioma app or with your bike computer.
For it to be successful, place the bike upright (not tilted) with the crank arms in a vertical position and make sure the pedals are free from any loads before proceeding.

Assioma UNO/DUO weighs only 151,5 g per pedal (with sensor).

The pedal's weight is more important than that of any other bike component, as any change in the pedaling speed results in a loss of energy directly proportional to the weight of the pedal itself.

With 194 g per pedal, Assioma PRO MX stands out as one of the lightest MTB power meters on the market.

The pedal's weight is more important than that of any other bike component as any change in the pedaling speed results in a loss of energy directly proportional to the weight of the pedal itself.
 

Assioma PRO RS weighs just 123,5 g per pedal (with sensor), which makes it the lightest road pedal-based power meter on the market.

The pedal's weight is more important than that of any other bike component as any change in the pedaling speed results in a loss of energy directly proportional to the weight of the pedal itself.
 

It depends on the model.

In the Assioma PRO line, all models offer the same +53mm q-factor, despite the discipline.
When it comes to Assioma UNO/DUO's, instead, the q-factor is +54mm.
Lastly, the q-factor of Assioma DUO-Shi varies according to the type of pedal body:
•    PD-R8000/6800: +65mm
•    PD-R7000/R550/R540: +64mm

Assioma features both ANT+ (pwr profile) and Bluetooth (cpp profile) connectivity, thus being compatible with most bike computers and apps in the market.

If you need a complete list of the ANT+ certified compatible head units, please visit This is Ant - Official Directory.

Assioma is compatible with the most famous cycling apps in the market including Zwift, Strava, Bkool, The Sufferfest, TrainerRoad, Rouvy and way more, for you to have plenty of choices to have fun!

Assioma features a smart auto-off system based on on pedal movement that prevents the battery from draining unintentionally. There is no need to turn Assioma off manually when not in use.
 

However, in certain situations, such as air travel, you may need to turn off electronic devices. To do this, select "Travel Mode" in the settings of your Favero Assioma app, just like you would on your phone.
 

Remember to bring the magnetic charger with you to exit "Travel Mode" and wake up the pedals.

There is no consensus on the use of the term online and on the market. In our case, we’ve adopted the most common definition: the distance between the center of the pedal axle and the surface where the cleats make contact with the pedal.

In particular, the stack height for the following for our models is:

•    Assioma PRO RS: 10,5mm (the lowest among all pedal-based power meters currently on the market)
•    Assioma PRO MX: 11,2 mm
•    Assioma DUO/UNO: 10,5mm (the lowest among all pedal-based power meters currently on the market)
•    Assioma DUO-Shi: the stack height varies according to the Shimano® pedal body it's mounted into. 

For additional info, check out the manufacturer's manual
 

Power in cycling is the product of Torque per Cadence.

Assioma measures the force (torque) exerted on the pedals thanks to 8 strain gauges placed around the axle, as most of the most accurate power meters on the market.

As for the velocity (cadence), it uses a special technology called IAV Power System, Instant Angular Velocity-based Power Calculation, that leverages an integrated gyroscope capable of detecting the Instant Angular Velocity (IAV) during the entire pedal stroke.

That’s why it can guarantee a declared accuracy of ±1% with any pedaling style: not only in regular or lab-controlled pedaling conditions.

• Assioma PRO RS is compatible with the Favero Assioma cleats provided or the original Shimano® SM-SH10, SM-SH11 and SM-SH12
• Assioma PRO MX is compatible with the Favero Assioma cleats provided or the original Shimano® SM-SH51 and SM-SH5
• Assioma DUO/UNO is compatible with the Favero Assioma cleats provided or the original Look® Kéo

Assioma road version is compatible with the spinning bikes. Just make sure you have an Allen key at hand to tighten the pedal on the crankarm.

As for Assioma PRO, instead, it's necessary that all the conditions listed in this document take place.

The serial numbers are a numerical combination that identify and distinguish your sensors and are particularly useful for raising a ticket with the Support Dept.

They can be found on a label in the user manual or on the outside of the box. Furthermore, they are visible by connecting the sensors to the app, on the home screen.

In the case of Assioma PRO MX, they are not to be confused with the numerical indication present in the pedal body itself behind the spring.

When it is installed for the first time (and every time it is mounted on a new bike), it is necessary for Assioma to carry out an internal self-calibration to be able to transmit the power data. Self-calibration occurs by performing a few dozen pedal strokes, while sitting and in a uniform manner. We therefore recommend pedaling on flat terrain for it to correctly happen.

Te and PS are available on Garmin head units featuring the ANT + connection.
To be able to see this data, you have to click on "settings", "sensors", "sensor details", "cycling dynamics" and enable the TE/PS option.

The automatic stand-by of your power meter can be changed on the Favero Assioma app. This feature is especially useful for triathletes who want to keep the sensors active even when Assioma is parked in transition areas.

Make sure Assioma is charged and remember to reset the timeout to its default value (5 minutes) to avoid unnecessary power consumption.

All the Assioma products use the ANT+ and Bluetooth data transmission system, which makes them compatible with basically any bike computer or app on the market.

Assioma PRO can be connected to up to 3 Bluetooth devices at a time.

Assioma PRO MX was designed to be used on bikes for use in the following disciplines:

• MTB XC
• Gravel
• Cyclocross

Assioma PRO must not be used with pedal extenders, crank shorteners, or any accessories that alter the crank arm setup, as they may cause damage. However, crank arm protectors are an exception and can be used without issue.

There are many advantages when it comes to using rechargeable batteries:

• No power ports nor battery compartments that can be closed incorrectly to avoid liquid seepages due to an incorrect lid closure or the wearing of the sealing gaskets

• During a cycling session, the components of the bike are subject to continuous and inevitable vibrations, not to mention dust and moisture infiltrations. Assioma’s battery is welded directly to the circuit board and lastly resinated to avoid any risk of bad functioning of the product due to faulty electrical contacts between the battery and the rest of the circuit

• No worries to replace, buy and dispose of the batteries – for the benefit of your wallet and the environment!

It won't happen with our rechargeable battery given that:

• You can always check the battery's level on the Assioma app
• A “low battery " signal will appear on your bike computer when you still have 8 operating hours

This problem may occur instead if you use non-rechargeable batteries (disposable batteries) for the following reasons:

• It is difficult to accurately measure their charge level as their discharge profile varies depending on both the type (alkaline, lithium ions, silver oxide, etc.), the manufacturer and their shelf life
• Power supply interruptions may occur due to oxidation or movement of the battery's electrical contacts.

Yes, if you wish to, you can easily carry out ordinary maintenance on your own without the need to send the product back to the factory or ask for the help of a mechanic.

On the Support section of our Favero Assioma app, you'll find all the necessary processes accurately described.
 

There is no need to send the product back for reparation. The pedal body is completely electronic-less, for it to be more sturdy against impacts and falls.

If you need to, though, you can easily remove it and replace it: all our spare parts are available in our online shop.

You can service Assioma DUO-Shi by simply cleaning or lubricating the bearings on your own. It's also possible to completely replace them with the appropriate kit.

Here you'll find a tutorial guiding you through the replacement process.

To clean Assioma you can simply use a damp cloth. Do not use aggressive chemicals such as alcohol, industrial or universal degreasers, oil, diesel and petroleum derivatives in general.

Assioma is totally waterproof (IP67 certified) so you can wash it with water, however, we advise you not to use high-pressure jets (pressure cleaner) as they could compromise the mechanical parts of the pedal body.

The recommended grease is lithium grease.

It is used to grease the thread when installing the pedal on the crank.
An occasional revision of the grease around the power spindle also favors the performance of the product over time.
It is recommended to use the specific kit provided in the package or available in the online shop.

Setting the crank arm length on the Favero Assioma app is useful only when this parameter cannot be changed directly on your bike computer.
In fact, if your bike computer already provides this option, the value set through the app would be overwritten.

The connection should happen smoothly with most training apps via the preset Bluetooth transmission mode.

If you're using Assioma DUO/DUO-Shi, in the very rare case that your app requires your pedals to communicate independently, simply go to the "compatibility with other apps" tab of the Favero Assioma app and choose the "dual-channel L/R" option.

Changing the "compatibility with other apps" setting will restart Assioma automatically: you'll have to pair Assioma via BLE again.

This feature applies only to our single-sided power meter pedals when connected via Bluetooth (not ANT+). Since the power sensor is on the left pedal only, the system is designed to automatically double the left-side power to display total power.
Therefore, the "Power halving" option is disabled by default in the Favero Assioma app.

You may encounter two scenarios depending on your training device:

• Scenario 1: If your training device does not double the power, you're all set—no changes needed. If you accidentally enable “Power halving”, your readings will be too low. Just turn it off again.
• Scenario 2: If your training device does double the power, you’ll see inflated values. In this case, enable “Power halving” in the Favero Assioma app to correct it.

Most training devices, unfortunately, don’t show whether they double left-side power. If you’re in doubt, check your power readings:

• If they look accurate, no change is needed
• If they seem too high, enable “Power halving”

For further support, feel free to get in touch with our Support Dept.

The upgrade from our single-sided versions to the dual-sided ones is possible with the upgrade kits available on our online shop.

 
On the Favero Assioma app you can associate the new right pedal to the left pedal by clicking on “from single-to-dual sided”.

This procedure allows for the static verification of the force measured by Assioma and it is useful if you suspect a constant under- or over-estimation of the power values by Assioma when compared with another power meter with an accuracy of at least ±1%.

Incorrect performance of the test may lead to a deterioration in the measuring performance. For any doubt, please contact our Technical Support.

Being the Assioma power pedals factory calibrated, there is no need to change this parameter.

Adjusting power may be useful in these cases only:

• Your bike computer does not allow you to set a specific crank-arm length (e.g. a pair of crank arms with different lengths)

• You want to align Assioma's power data with that of an indoor trainer so that you can train indoors and on the road with the same power reference.

Yes, it is. Pairing Assioma with the Favero Assioma app is necessary to enable data transmission and it also determines the start of the warranty period.

Make sure that Assioma is switched on and not connected via Bluetooth to any other devices otherwise your phone won't be able to find it.
Android users might be required to enable geolocation even though the app itself does not use it.

Open the Favero Assioma app. At first, you'll be asked to pair your left sensor (master) only. 

If you have a dual-sided version, once paired the left sensor, the right one will appear on the results screen and you'll have to pair it as well.

Since the app might as well detect other surrounding sensors (e.g. nearby riders also using Assioma), make sure to select your serial numbers number correctly.
If you don't remember your serial numbers, you can check them on the outside of the Assioma box or on the manual.

You can install any firmware updates directly on the Favero Assioma app available for free for both Android and iOS.
Before updating, make sure that the battery is sufficiently charged (about 75%). The operation usually takes a few minutes.
