Cycling Cadence Sensors

A cadence sensor consists of three main parts: a spoke magnet, a cadence magnet and an electronics pod. The spoke magnet attaches to one of the spokes on your rear wheel, while the cadence magnet attaches to one of the crank arms on your pedals. The electronics pod mounts on your bike frame near the rear wheel and contains two sensors that detect the passing of the magnets. The pod then transmits the data wirelessly to your bike computer or smartphone via Bluetooth or ANT+.

Different Types Available

There are two types of cadence sensors: single-sensor and dual-sensor. A single-sensor device only measures cadence, while a dual-sensor device also measures speed by calculating the distance travelled by the rear wheel. Some dual-sensor devices also measure power output by estimating how much force you apply to the pedals.

Cadence sensors can help you improve your cycling performance by providing feedback on your pedalling technique and efficiency. For example, if you pedal too slowly, you might be wasting energy and putting more strain on your muscles and joints. If you pedal too fast, you might lose momentum and stability. You can pedal more smoothly and comfortably by finding your optimal cadence range for different situations.

They can also help you train more effectively by allowing you to set specific goals and monitor your progress. For example, you can aim for a higher average cadence over a longer distance or time to improve your endurance. You can aim for a higher peak cadence over a shorter distance or time to improve your sprinting or climbing ability.
