Review by Petr Minarik
Favero Assioma pedal power meters are one of the best power meters on the market, thanks to their ease of installation, accuracy, and reliability. I use them as my main power source. They are more affordable than most competitors while providing better value. Their biggest disadvantage is that they are not available for Shimano SPD-SL cleats (unless you use DUO-Shi spindles). Depending on your budget and preference, you can buy Favero Assioma DUO (dual-sided power meter) or Favero Assioma UNO (left-sided power meter). I fully recommend them.
What's the difference?
Favero Assioma DUO are ideal for riders who look for an easily transferable, reliable, accurate, and consistent dual-sided power meter.
Favero Assioma UNO is a more affordable, single-sided power meter, so it estimates the power output of your right leg. It also won’t provide you with an L/R balance and other advanced metrics.
