Garmin Cadence Sensor 2 | Wireless Bike Cadence Sensor

The Garmin Cadence Sensor 2 adds precise pedaling-cadence data to almost any bike — without magnets, exposed wires, or fussy alignment. The sensor straps to the inside of your non-drive-side crank arm with the included rubber bands and detects pedal strokes through built-in motion sensing. It connects via ANT+ and Bluetooth Low Energy, so it pairs with Garmin Edge computers, Garmin smartwatches, the Garmin Connect app on your smartphone, the Tacx Training app, indoor trainers, and third-party apps like Zwift. Slim and unobtrusive, it stays put through rough roads and weather and runs a full year on a single coin-cell battery.
