Cadence Sensor 2

The second generation cadence sensor by GARMIN determines and stores your cadence values via ANT+ and Bluetooth Low Energy (BLE). Thanks to this multi connectivity, the cadence sensor is compatible with a wide range of devices with which it can be connected simultaneously.
Just like the predecessor, the cadence sensor 2 uses a high-sensitivity accelerometer. It is simply fitted to the left crank arm, where it calibrates itself and precisely measures the number of pedal strokes per minute. An additional magnet is not required.
