*The COROS cadence sensor is available for purchase in Canada, the United Kingdom, and the United States.
The COROS Bike Speed and Cadence Sensors pair to bike computers, GPS watches, and other devices via Bluetooth.
To pair the sensors with your COROS DURA or COROS watch, go to the System > Accessories > Add Bluetooth page on the device to search for and pair with the sensors.
To pair with third party bike computers, indoor trainers, apps, and other devices, please refer to your device's user manual to search for and pair with the speed and cadence sensors.
The speed and cadence sensors can each be paired with up to two Bluetooth devices simultaneously. ANT+ connections are not supported.
When pairing the speed sensor, make sure to select your wheel circumference. When pairing the bike speed sensor to a device for the first time, the device will prompt you to enter the wheel circumference of your bike to get the most accurate speed and distance measurements.
On your COROS DURA or COROS watch, you can adjust the wheel circumference at any time by going to System > Accessories > select the COROS Bike Speed Sensor > Wheel Circumference.
