Monitor your speed and cadence as you ride with these easy-to-install wireless sensors. With no magnets or other exposed parts to line up, these sensors are easy to install, maintain and move between bikes. 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.

• 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.
