Product description

Assioma is a pedal for racing bicycles with a quick clip system, provided with power sensor to measure the force applied to the pedal during the pedal stroke.
This pedal includes the function of cadence meter and can calculate the power of a single leg in real time, sending it to the bike computer.
It is provided with a rechargeable battery designed to guarantee an operating time of at least 50 hours during many years of use. Therefore, there are no openings with gaskets for the replacement of the battery.
Assioma is fully sealed (IP67) thanks to its case without openings and all its internal components are immersed in a special filling resin.

For radio communication, Assioma is compatible with the ANT+ standard and Bluetooth v4.0 standard, or later version. The use of Bluetooth v4.0 in smartphones started in 2011 – 2012.

Warnings

Please carefully read this manual and the safety instructions before installing the product. An incorrect installation may lead to accidents and possible damage to things and/or injury to people.

If you have any doubts about your ability to install the product, we recommend you to ask for the assistance of a specialized mechanic. An incorrect installation may cause or result in irreparable damage to the product which shall not be covered by the warranty. Before starting to ride, check that the force necessary to release your shoe from the pedal is suitable.

Switching on Assioma

Assioma will automatically switch on by turning the pedals or starting to ride and will automatically switch off after 5 minutes of inactivity.

When using Assioma for the first time, connect it to the supplied battery charger for a few seconds to switch it on. Follow the same procedure if “Travel mode” has been activated from the Favero Assioma app.

If the LEDs do not blink, charge the battery as indicated in Chap. 12. For LED behavior read Chap. 18.

Activating Assioma

Assioma must be activated to measure the power and cadence. If it is not activated, such measuring will not be performed. The activation also determines the start of the warranty period, allows updating the software and sending diagnostic reports to check the correct operation of the product.
Activation is obtained with the specific “Favero Assioma” app, available both for iOS and Android. The app can be downloaded free of charge.

Make sure that your smartphone is compatible with the Bluetooth v4.0 standard or later versions, and that your internet connections is active.

Open the app and follow the instructions to perform the search, the connection to your device and the activation. If Assioma does not appear in the search section, make sure that it is not already connected via Bluetooth to another device (e.g. bike computer). For more information, read the FAQs on the website: cycling.favero.com.

Fixing the pedals to the crank-arms

Washer use

The washers supplied are only necessary in the following cases:

• The crank-arm producer requires the use of a washer.
• The crank-arm has a recessed seat and one or two washers must be used to ensure a free space between sensor and crank-arm.

Pressing the sensor against the crank-arm when tightening the pedal may damage it. This operation would invalidate the warranty. If necessary, use 1 or 2 washers to ensure a free space of at least 1 mm between the sensor and crank- arm.

If a cadence sensor is fitted near the pedal, remove it to avoid any contact with the Assioma sensor.

Tightening the pedals

Before tightening the pedals, apply a thin layer of grease to the pedal axle thread.
Tighten the pedal to the crank-arm using the supplied 8 mm hexagonal wrench at a tightening torque of about 35-40 Nm (25-30 ft lb), a standard torque for the tightening of many pedals. If the crank-arm producer specifies a different tightening torque, apply it.

Pay attention to the rotation direction:

• Tighten the left pedal counter-clockwise (facing the pedal).
• Tighten the right pedal clockwise (facing the pedal).

Cleat fixing, shoe position check and cleat release force adjustment

Cleat fixing

Use only the supplied cleats (red cleats, float 6°) or original LOOK Kéo cleats. The use of non-original LOOK Kéo compatible cleats may be unsuitable and any damage to the product will not be covered by the warranty.

To fix the cleats, use the supplied screws and washers.
Align the cleat in the preferred position and tighten the screws with a tightening force of 4÷6 Nm (3÷4.5 ft lb), as for most of the cleats on the market.

Black cleats are also available for separate purchase (float 0°), Art. 771-40.

Shoe position check

Thanks to its reduced dimensions, the sensor never comes into contact with the shoe even when large size or flat-soled footwear is worn.

Before starting to ride, check that the distance between the shoe and the sensor is at least 2 mm. Do not use the product if the sensor is in contact with the shoe, the shoe cover or the cleat, as it can be damaged and this would invalidate the warranty.

If the distance between the sensor and the shoe is less than 2 mm, move the cleat to the most appropriate position or insert spacer Art.771-45 between the cleat and the shoe sole.

Cleat release force adjustment

Before starting to ride, try to release the shoe several times and make sure that the release force is suitable.
The correct direction to unclip is external to the bike.

The spring tension can be adjusted using the screw shown in the picture. To increase the tension turn clockwise; to decrease the tension, turn counter- clockwise.
Use a 3 mm wrench (not supplied).

Bike computer configuration

Pairing Assioma to the bike computer

The pairing procedure associates Assioma to the bike computer to start the radio communication between the two devices.

Please read the bike computer manual to learn how it performs the search and pairing of a power sensor. Make sure that Assioma is switched on before proceeding (Chap. 5).

Each Assioma has a unique 5-digit identification number (ANT+ ID) written on the packaging. This number identifies Assioma in the list of devices which can be paired with the bike computer.

Bike computers require that only the left pedal be paired. The left pedal will transmit also the data collected by the associated right pedal.

On Bluetooth bike computers and other devices with Cycling Power Profile (CPP), the left pedal can be recognized by an L that follows the identification number.

Important warnings to avoid communication problems during pairing:

• Make sure there are no other power meters switched on nearby (10 m).
• The bike computer must be within 2 m from Assioma.
• For Bluetooth devices only: make sure Assioma has not already been paired or connected via Bluetooth to another device or app.
• If you set Assioma DUO in “Dual channel L/R” mode, the right pedal sensor can be recognized by the R ID identification number written on the outside of the box. For more information, see Chap. 17.

Configuration of power fields

Once the pairing procedure has been completed (Chap. 9.1), it is possible to configure the bike computer so that it displays the power data in the preferred way: please refer to the bike computer manual.
It is recommended to at least set the following parameters: 3 second power, 30 second power, cadence, 30 second average balance.

Crank-arm length

The crank-arm length affects power calculation: Assioma must know this length. An incorrect value will lead to incorrect power values.
Please refer to the bike computer manual to learn how to set the crank-arm length.
If the crank-arm length cannot be set on the bike computer, set this parameter using the Favero Assioma App.

Do not set the crank-arm length via the Favero Assioma App if the bike computer already allows this operation; the set value would be overwritten.

Manual and automatic calibration (zero-offset)

Each Assioma sensor is factory calibrated to ensure its guaranteed precision under any operating conditions, including ambient temperature variations, for which automatic compensation from -10°C to +60°C is active. No return to the Manufacturer is therefore necessary for periodic factory calibration.

With the 4.75 firmware update, Assioma introduces the automatic calibration (zero-offset) functionality, a sophisticated algorithm considering different aspects over time.
The only suggested precaution is to store the bike upright (not tilted), with no load applied on the pedals. Automatic calibration is independent of the crank position.

Manual calibration is, therefore, not necessary, yet it is possible to keep on performing it in a few seconds via the Assioma app or bike computers/third- party-apps. By doing so, the values registered by the last automatic calibration will be overwritten by those of the manual one.

Manual calibration is required at first installation and any time Assioma is moved between bikes.

How to perform manual calibration:

• Switch on Assioma.
• Turn on the bike computer or start an app (this function is available also on the Assioma app). If Assioma is not detected, make sure it is not already connected via Bluetooth to another device.
• Release the shoes from the pedals and make sure that they are not in contact with anything.
• Place the bike upright (not tilted) keeping it as still as possible. Otherwise, it will not be possible to complete the calibration. Reposition your bike before trying again.
• Place the crank-arms in vertical position.
• Read the bike computer manual to learn how to:
• Open the power sensor menu.
• Press the “Calibration” or “Zero Offset” button.
• Make sure that manual calibration was successful; usually the display shows a confirmation message or a 0 (zero).
• Repeat the operation if an error occurs.

Sometimes manual calibration is slowed down or prevented if other ANT+ sensors (e.g. cardio band, cadence sensor) are enabled but switched off on the bike computer, as the bike computer searches them but cannot find them. In this case, it is necessary to switch them on, or disable them temporarily on the bike computer.

Using Assioma for the first time on road or rollers

On the first installation, Assioma will not send any power data to the bike computer until it has completed the internal self-calibration. Assioma self-calibrates while cycling by making a few tens of complete pedal strokes. To speed up the procedure, it is advisable to cycle seated, at a uniform pace and on a leveled road. Self-calibration can be considered completed once Assioma sends the power data to the bike computer.

Battery charge

Assioma has an internal rechargeable lithium battery with at least 50-hour life span. The capacity of each battery is tested during the manufacturing process.

The battery life is very long thanks to the low number of battery charges required.

If you use Assioma for 15 hours a week, it is sufficient to charge it once every 3 weeks.
The battery can also be charged when it is only partially discharged: this will further increase its life span.

If the product is not used for long periods of time, charge the battery anyway at least every 3 months in order to avoid the risk of irretrievably damaging the product.

When the battery of a pedal runs low, the bike computer will display a warning. The remaining battery life, after a low battery warning, will be of about 8 hours.

To charge the batteries, follow the procedure below for each sensor:

• Connect the battery charger supplied to an electrical socket.
• Connect the USB cable supplied to the battery charger.
• Insert the micro USB connector into the magnetic connector (see the picture).
• If the sensor contacts are wet or dirty, dry or clean them with a dry cloth.
• Connect the magnetic connector to the pedal as indicated in the picture: the LEDs switch on and remain switched on during the entire recharging. Once recharging has been completed, the LEDS will blink every 0.5 seconds.

Recharging a completely discharged battery takes about 6 hours.

Recharge at a temperature ranging between 5°C and 40°C. Beyond this range, recharging is blocked to protect battery functionality.

If necessary, Assioma can also be charged with a common smartphone battery charger, instead of using the one supplied.

When a socket for battery charger is not available, a common “power bank” can be used.

To charge two sensors at the same time, use a model with 2 USB ports. Some models are not able to fully charge the battery as their minimum charge current is higher than 50 mA.

Transforming Assioma UNO into Assioma DUO

Assioma UNO measures the power only on the left pedal. It is possible to buy the right pedal with the sensor (art. 772-51) at a later date and therefore pass to a system equal to Assioma DUO. The left pedal must be paired to the new right pedal using the Favero Assioma app.

Transforming Assioma UNO into Assioma DUO

Assioma UNO measures the power only on the left pedal. It is possible to buy the right pedal with the sensor (art. 772-51) at a later date and therefore pass to a system equal to Assioma DUO. The left pedal must be paired to the new right pedal using the Favero Assioma app.

Removing the pedals

To remove the pedal, use the supplied 8 mm hexagonal wrench:

• Unscrew the LEFT pedal CLOCKWISE (facing it).
• Unscrew the RIGHT pedal COUNTER-CLOCKWISE (facing it).

Reinstalling the pedals (on another bicycle)

Any time the pedals are moved from one bicycle to another, manual calibration must be performed (Chap. 10).
Once the pedals are reinstalled, the power and cadence data displayed on the bike computer are no longer reliable until Assioma performs an internal self-calibration.

Assioma self-calibrates while cycling by making a few tens of pedal turns. To speed up the procedure, it is advisable to ride seated, at a uniform pace and on a leveled road.

Compatible bike computers

Assioma is compatible with any ANT+ bike computers with Bike Power (PWR) profile.
For the complete list of the ANT+ certified products, visit the website:
http://www.thisisant.com/directory/ (select “Bike Computers” in the Categories menu).
It is advisable to install the latest firmware version available from the bike computer manufacturer.

If you buy a new bike computer, we suggest the purchase of a model having a “CT” (Crank Torque) ANT+ profile, which ensures a better stability of the power being displayed.

App compatibility

Assioma is preset in a “Unified channel L” mode that ensures the greatest possible compatibility with apps that manage data transmitted by power meters.

A small set of Bluetooth bike computers and apps might require a change in the preset “Compatibility with other apps” parameter from the Favero Assioma app.
Before changing the “Unified channel L” setting to “Dual channel L/R”, we recommend contacting your cycling app Support to find out what the best solution is.
