Keo Power and Garmin Vector pedal power meters
After a couple years of speculation, pedal-based power meters are finally ready for the road. Look and Polar have teamed up to create Keo Power and Garmin purchased tech start-up Metrigear to produce Vector, their pedal power meter. Measuring power through the pedal creates two potential benefits. First, they can be swapped between bikes or wheels can be swapped on a single bike. Second, they have the potential to measure the power that is wasted to create a cycling efficiency score that is more useful than current efficiency measures.
