Monitor your speed and cadence as you ride with these easy-to-install wireless sensors. With no magnets or exposed parts to line up, they're 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 track speed and distance, even without a head unit.

The Cadence Sensor 2 fastens to any size crank arm and measures pedal strokes per minute to help you make the most of your training.

Send live speed, distance, and cadence data to compatible training apps or displays using ANT+® connectivity and BLUETOOTH® Low Energy technology. With both sensors on your bike, track your progress and work toward a new personal best.
