Favero Electronics

The Uno measures power only on the left pedal and then extrapolates the right (x2), whilst the Duo measures both sides independently. The Uno is cheaper and very reliable for cyclists with a symmetrical pedalling style. The Duo displays the left/right balance (e.g. 48%/52%), which is useful after an injury or to correct a muscular imbalance. The good news is that an Uno can be upgraded to a Duo by purchasing a second compatible pedal.

Yes: Assioma pedals transmit via ANT+ and Bluetooth, compatible with almost all GPS devices and apps on the market. Garmin Edge, Wahoo Elemnt, Polar, Hammerhead Karoo, Zwift, TrainingPeaks, Strava... all these platforms read Assioma data. Simultaneous connection to three Bluetooth devices is available on Assioma Pro models. The Favero app allows you to configure the cleats, manage the battery and perform firmware updates.

Favero claims an accuracy of ±1%, guaranteed regardless of cadence or pedalling style, including with oval chainrings. This accuracy is ensured by the IAV Power (Instantaneous Angular Velocity) system: a built-in gyroscope measures the actual instantaneous angular velocity, unlike other sensors which use an average per revolution (which introduces an additional error). Independent tests confirm the stability and repeatability of the Assioma over time.

Yes: the Assioma DUO-Shi allows the sensor to be integrated into Shimano SPD-SL pedal bodies (PD-R8000, PD-R7000, PD-6800, PD-R550, PD-R540). The advantage: you can keep the familiar Shimano platform whilst benefiting from Favero’s precision. The downside: the Q-factor (distance between foot and crank) increases from 54 to 64–65 mm, which may bother cyclists sensitive to knee spacing. For cyclists already using Look cleats (3-bolt): the standard Assioma Duo is more versatile.

The battery life is 50 hours per full charge, using a rechargeable lithium battery via a proprietary magnetic connector. Charging is quick: around 1½ hours for a full cycle. The magnetic connector attaches to the pedal without needing to fiddle with the cable. The Assioma app displays the battery level as a percentage and alerts you before it runs out.

Yes, Favero Electronics S.r.l. is an Italian company based in Arcade, in the province of Treviso (Veneto). The brand specialises in sports electronics and initially marketed the bePRO sensors before launching the Assioma. Manufacturing in Italy is a key selling point, highlighted for quality control and responsive after-sales service. Favero sells directly via its website cycling.favero.com with delivery within 3–4 working days.

The Zero Offset must be performed before every ride: with the crank vertical, stationary, and no weight on the pedals. This operation is carried out directly from the GPS bike computer (Sensors menu > Calibration) or via the Assioma app. It takes 5 seconds and ensures measurement accuracy by compensating for temperature variations. An offset too far from zero may indicate an installation issue or sensor drift.

Yes: this is one of the key advantages of pedal sensors: they can be removed and refitted using just an 8 mm Allen key. A triathlete with two bikes (road + time trial) can transfer the pedals in 2 minutes. The only precaution: reapply grease evenly to the thread and reset the Offset Zero. The crank length must also be checked and updated in the GPS device if it changes.

The Assioma Pro provides advanced metrics: power phase, time spent out of the saddle vs. in the saddle, left/right balance, and torque angle. The Power Phase indicates the angle of the pedal stroke at which you generate power (ideally between 90° and 270° of rotation). Time spent out of the saddle and the associated power output allow you to analyse specific muscle work. This data is compatible with Garmin Edge computers (Cycling Dynamics) and certain advanced analysis platforms.
