Single-sided or dual-sided: the same Assioma pedal design with one sensor or two.
Verdict
Buy the Favero Assioma UNO if you want the lowest-cost pedal power meter: the sensor is on the left pedal only and the app estimates the total. Buy the Assioma DUO if you want power from both legs and separate left and right data. Both list plus or minus 1 percent accuracy and are Look Keo compatible.
