The speed sensor 2 attaches to the hub of either wheel and self-calibrates with your Edge® cycling computer or compatible Garmin device to give you accurate speed and distance at all times — even without a head unit.

The cadence sensor 2 fastens to any size crank arm and measures pedal strokes per minute so you can get the most out of your training.

Send live speed, distance and cadence data to compatible training apps or displays by using ANT+® connectivity and BLUETOOTH® Low Energy technology.

With both of these sensors on your bike, you can work to improve your personal best or see where you stand against the pros.

Heart rate strap transmits real-time heart rate data over ANT+® connectivity and BLUETOOTH® Low Energy technology, giving you more options to train indoors, outdoors or even online. With it, you’ll be able to consistently receive accurate heart rate on your Garmin device, in online training apps such as Zwift or even the compatible fitness equipment in your favorite class at the gym. So however you like to train, you’ll get the accurate, real-time heart rate you need to take your performance to the next level.
