PowerTap P1

The draw: Simple to swap between bikes

If you’re looking for the ability to move your power meter between bikes in a couple minutes with just a hex wrench, the P1 is your answer. This pedal-based power meter measures both legs independently, and then transmits your wattage over ANT+ and Bluetooth Smart. That makes it compatible with your Garmin, Polar and favorite cycling apps—all while being just as accurate as any unit on the market. An update planned for later this spring will bring advanced pedaling efficiency metrics as well.
