Favero Assioma Uno Power Meter Pedals

Item number: 73511

The Favero Assioma Uno power meter pedals - it's the facts that count

The Assioma Uno power meter pedals by Favero, unlike the Assioma Duo, perform a one-sided power measurement on the left leg. Torque efficiency and pedal stroke are only determined on the left side and you do not get any information about the right-left balance. The pedal's ground-breaking technology provides ultra-precise and reliable wattage readings, allowing you to redefine your goals. Based on hard facts, not just estimates, you'll get more out of your pedal strokes and make your training more efficient than ever.
The Assioma Uno can be installed as easily as normal pedals and quickly transferred from one bike to another. Communication with your smartphone or bike computer is wireless via Bluetooth or ANT+. As an additional feature, which previous versions did not have, is the continuous release hardness adjustment from 8 to 20 Nm.
Favero Electronics has over 30 years of experience in the field of electronic sports equipment and works closely with athletes. The Assioma Uno pedals, for example, have been extensively tested by the UCI Team Bardiani-CSF and successfully tried out in tough racing conditions.
And if a one-sided measurement one day should not be enough for you: Upgrading from Uno to Duo is possible at any time.

Assioma Uno Functionality
Power is measured in cycling by relating the force acting on the pedals to the pedalling speed (frequency): power = torque x cadence. Assioma is a pedal for Road cyclists, equipped with a sensor to measure the force applied to the pedal while pedalling. Assioma Uno integrates the cadence function and calculates the power of the left leg in real time. The left pedal sends its data to the bike computer. Favero power meter pedals provide an objective value which, unlike heart rate, cannot be influenced by external factors such as high temperatures, psychological stress, caffeine consumption, etc.

Ich habe schon seit über einem Jahr die Assioma Duo an meinem Rennrad und habe mir die Uno für mein Gravelbike (Schlechtwetterrad) gekauft, weil mir das Umschrauben dann doch zu lästig war. Hat man sich erst einmal an die Leistungswerte gewöhnt, fühlt man sich plötzlich nackig so ganz ohne ;) Gefühlt und gemessen sind das deutliche Unterschiede, auch ist die Herzfrequenz nicht immer so passen. Ich möchte nie wieder ohne fahren.

Die Favero Assioma sind sehr zuverlässig, in all der Zeit mit der Duo und den zwei Monaten Uno habe ich (wie auch Vereinskollegen) nie irgendwelche Zicken gehabt (was man von einem Wettbewerbsprodukt mit G wohl nicht sagen kann).
Der "Knubbel" mit dem Akku fällt überhaupt nicht auf und stört auch nicht. Die Akkulaufzeit ist gewaltig lang und wenn sie zur Neige geht, meldet sich mein Wahoo Radcomputer rechtzeitig das die Pedale mal wieder Saft brauchen. Das Ladekabel ist sehr lang und mit der Magnetfunktion ganz einfach angestöpselt.
Die Duo (beidseitige Messung) brauche ich eigentlich doch nicht bzw. ist Luxus. Die Auswertungen "links/rechts Unterschied", "runder Tritt" etc. werte ich nicht aus und bei einem minimalen links/rechts Verteilungsunterschied spielt das auch keine Rolle. Da würde ich eher die Uno Pedale kaufen als gar keine Leistungsmessung (für den Fall das die jemand zu teuer wird).
An die Look Kéo Cleats habe ich mich schnell gewöhnt, mittlerweile würde ich auch nicht mehr zurück wollen.
