Not only are there a ton of new power meter options available in 2017, they're getting cheaper and more compatible, too. Polar partnered with cycling pedal giant Look to create the Keo Power—a new model we really like—but if you're looking for something new and innovative, Luck takes the cake. Their new power meter is included in the sole of their custom-made shoes. That means zero installation, lighter overall weight, and the ability to easily transfer your power meter from one bike to another. Overall cost for the custom shoes will be around $250 a pair.
