The Kífo Power Dual Mode is the third generation of LOOK power meter pedals. The measurements of pedaling effort are provided by eight strain gauges installed in the axle of the pedal. This ensures a reliable power measurement because it is calculated directly where the force is applied by the rider. With the Essential version, data is only measured from the left pedal. In addition to the power and cadence reading, the Kífo Power measures your strength, and pedaling efficiency (dead spots/regularity). Compatible with Bluetooth and ANT+ devices.
