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, the Garmin Bike Speed Sensor 2 and Cadence Sensor 2 Bundle 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.
• 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.
