Garmin brings power to the pedal with the Vector. Built in conjunction with Look Keo pedals, the Vector offers precise power measurement in a rugged, ultra-convenient, discreet package. Garmin encased sensitive strain gauges inside the stainless steel pedal spindles for years of durability and accuracy to within +/- 2%. The Vector is essentially two separate power meters and measures power from both legs, meaning you have the data to correct discrepancies between your left and right sides. Now you can eke out those last few watts and maximize your pedaling economy. Switching the pedals and pods between bikes is blissfully hassle-free and takes less time than getting kitted up. The pedal bodies are built of tough, light carbon, while the battery/ANT+ pods hang protected beneath the crank arms. At a nimble 312 grams including pedal weight, the Vector is one of the lightest power meters available.
