The ANT+ Speed / Cadence sensor fits to any bike transmitting real time speed or cadence data wirelessly to any ANT+ compatible bike computer. The tiny sensor is fitted to the bike forks or chainstay and detects speed or cadence from the lightweight magnet attached to the wheel spokes or crank arm. Ideal for cyclists who want to accurately monitor their speed and distance data both indoor and outdoors. 

The sensor has a non-volatile memory feature integrated into the sensor allowing the unique device identity to be held during battery change. This eliminates the need for repeat pairing after battery replacement.
