Why is everyone talking about the Favero Assioma PRO MX: the most technical and advanced pedal power meter for MTB, gravel, and CX?

Favero Electronics is the Italian manufacturer that has revolutionized the market for cycling power meters and in its catalog you will find the range "Assioma PRO MX" with which the brand identifies all the Favero power meters available for off-road use. Without a doubt this is one of the components that has been generating the most buzz in recent months and here we bring you the keys to its success.

Favero Assioma PRO MX: resistant, lightweight, precise and with the "Made in Italy" seal

With the word "PRO" Favero identifies the changes applied to the power axis structure (sensor), while "MX" refers to the disciplines for which the product can be used: MTB XC, gravel, and CX.

Designed and manufactured entirely in Italy, the Assioma PRO MX opts for an extremely advanced technical approach, both in its internal architecture and in the details of the pedal body. It is available in three versions and below we give you the most outstanding keys of this device.

The Assioma PRO MX comes in three variants to adapt to the different needs of cyclists:

• Assioma PRO MX-2: with sensors on both pedals - €614 + VAT
• Assioma PRO MX-1 with sensor only on the left pedal - €368 + VAT
• Assioma PRO MX-UP: MX-1 to MX-2 upgrade kit - €352 + VAT

Everything goes inside the axis: Favero's technical key

Favero has achieved what many consider a milestone in pedal power meter design: housing absolutely all electronic components, strain gauges (the sensor that measures deformation and extracts the power we are applying) and battery inside a pedal axis made of stainless steel. This solution, while complex in terms of engineering due to the very limited space, offers significant advantages:

What it offers:

• Greater reliability. Connection failures typical of replaceable batteries with pressure contacts are avoided.
• Rechargeable battery soldered to the circuit, less exposed to vibrations, water, or mud.
• Removable pedal body without risks: the electronic system remains protected inside the axis.
• Replaceable external parts at low cost, like a conventional pedal without electronics.

For example, the Rally models from Garmin house the strain gauges and electronics inside the axis, but their replaceable battery is located outside the axis, and in the SRM X-Power, it is the strain gauges that are located on the outside. This means that to communicate both modules you need several contact points from the outside to the inside of the axis that can lead to loss of precision and resistance.

In that sense, Favero has chosen to prioritize excellence with a non-replaceable battery that offers an autonomy of 60 hours, slightly lower than some models with disposable batteries, but undoubtedly sufficient for the majority of users.

A pedal body created from scratch to last

Continuing with the protection of the electronic heart and prioritizing resistance, Favero has completely designed the pedal body:

• 6061-T6 aluminum (no plastics): maximum impact resistance.
• High dynamic load needle bearings (400 kg per roller).
• Stack height of only 11.2?mm: improves biomechanics and reduces impact risks.
• Clipless treated for improved wear resistance.
• Design without protruding parts, including the cap, to withstand falls.

Superior precision with the IAV Power system

Another of the great differences of the Assioma compared to the competition is how it calculates power. Most power meters only estimate the average angular speed of each pedal stroke, assuming it is constant, which is not true, especially in accelerations, sprints, or with oval chainrings.

Favero uses an integrated gyroscope that measures instantaneous angular speed (IAV) throughout the pedaling cycle, ensuring:

• Real precision of ±1?%, even in variable conditions
• Total compatibility with oval chainrings
• Reliability in any type of terrain and effort

Advanced analysis: IAV Cycling Dynamics

The Assioma PRO MX also records and transmits three key metrics called IAV Cycling Dynamics for performance analysis:

• PCO (Platform Center Offset): measures how force is distributed on the pedal platform
• Power Phase (PP): identifies the effective segment of the pedal stroke and the power peak
• Cyclist's position: shows time spent sitting or standing and its influence on performance

These metrics are compatible with ANT+ and can be viewed on advanced cycle computers like Garmin or Wahoo, and are also available in the Favero mobile app.

Made in Italy

Favero has decisively opted for an approach that combines design, local manufacturing, and sustainability. The Assioma PRO MX is entirely manufactured in its own facilities in Italy, ensuring total control over the quality of the product.

Furthermore, attention has been paid to every detail of the packaging: the packaging is completely recyclable and the inner tray is made of biodegradable paper. To reduce paper usage, the documentation has been digitized, and in order to avoid unnecessary electronic waste generation, the device does not include a charger, allowing the user to reuse those they already have at home.

The most common doubts about Favero Assioma PRO MX pedals

Some cyclists ask the same questions when choosing pedals with a power meter or directly choosing one of these Favero Assioma PRO MX, so here are some answers to the most common ones.

Is a pedal power meter more fragile?

Not in this case. Favero's design protects the electronics inside the axis and leaves the exterior as easily replaceable mechanical part. In addition, it uses aluminum, robust bearings, and special treatment in the engagement areas.

What about the rechargeable battery in the long term?

Favero states that its battery can last more than 30,000 hours of use, with a loss of only 20% of capacity after 500 full cycles. In other words, it will last many years without worries.

Is it compatible with my cycle computer or app?

Yes. The Assioma PRO MX is compatible with all ANT+ and Bluetooth cycle computers, including Garmin, Wahoo, Bryton, Apple Watch, and mobile apps. It can connect to up to 3 Bluetooth devices at the same time.

Do I need to calibrate it before each ride?

It is not necessary. The automatic calibration system does it for you every time you store the bike without load on the pedals. Manual calibration is only necessary when installing or changing it from one bike to another.

Favero Assioma PRO MX pedals are very easy to recommend

The Assioma PRO MX is probably the most advanced pedal power meter for MTB, gravel, and CX on the market. Favero has opted for a technical architecture that prioritizes reliability, real precision, and durability, without compromising weight or compatibility.

And after testing them for quite some time, here you can read our test, we can say that those looking for an uncompromising power meter with a long-term vision will find in the Assioma PRO MX a reliable, complete tool designed for maximum performance.
