Favero Assioma DUO-Shimano Road Bike Power Meter

Extremely reliable power measurement with a Shimano SPD-SL pedal? With the Favero Assioma DUO-Shi this is possible! This powermeter shafts easily and quickly into a Shimano SPD-SL body. Then you have all the well-known functions of Favero with the reliable and popular SPD-SL system.

Always reliable measurements
The Assioma DUO-Shi power meter pedal axles display your wattage very accurately. Weather conditions do not affect the measurement, as the DUO-SHi automatically compensates for temperature differences between -10 and +60 degrees Celsius.

Instantaneous Angular Velocity
The Favero Assioma DUO-Shi power meter pedals measure angular velocity while pedalling with a built-in gyroscope. The technique they use to measure this is called Favero IAV, or Instantaneous Angular Velocity. Thanks to this technique, these pedals can very accurately determine total power delivered, left-right ratio and effective pedal stroke, among other things. The Favero Assioma DUO-Shi power meter pedals are therefore an ideal partner during your training sessions, whatever the situation!

Suitable for all types of chainrings
The Assioma DUO-Shi measure exactly how fast your legs spin while pedalling. Differences in pedalling speed and motion are also measured. This makes the DUO-Shi extremely suitable for both round and oval chainrings.

Internal battery
The pedals use an internal rechargeable battery that lasts up to 50 hours on a charge. While charging, the pedals can also easily remain on the bike. Not only is the included charging cable two metres long, the magnetic attachment ensures you don't have to search for a charging port every time.

Please note! The Q factor (distance between the outer sides of the cranks) of the pedals is higher than you are probably used to. This means your feet will probably be further apart than with your regular pedals.
