SIGMA STS Cadence Sensor - Wireless Cadence Meter for Precision Cycling TrainingElevate your cycling performance and revolutionize your training with the SIGMA STS Cadence Sensor. Designed for ambitious cyclists and data-driven athletes, this essential accessory provides precise, real-time measurement of your pedal revolutions per minute (RPM). Understanding and controlling your cadence is the key to unlocking greater efficiency, improving endurance, and preventing strain, allowing you to ride faster and longer with less effort. This complete set provides everything you need to start tracking this crucial performance metric right out of the box.The core of this device is the renowned SIGMA Transmission System (STS). This digitally coded, three-channel wireless transmission technology ensures a robust and completely interference-free connection to your compatible bike computer. Say goodbye to data dropouts or crosstalk from other electronic devices or nearby riders. The STS system delivers a crystal-clear, reliable data stream, so you can trust the numbers on your screen and focus entirely on your effort. Whether you´re in a crowded peloton or on a solo training ride, your cadence data will be flawless.By monitoring your cadence, you can train more effectively. Maintain a consistent, optimal RPM to ensure a smooth and powerful pedal stroke, often referred to as ´souplesse´. This helps you avoid mashing heavy gears, a practice that can lead to premature muscle fatigue and potential knee injuries. Instead, you can perform structured workouts based on specific cadence zones, building both your cardiovascular fitness and your neuromuscular efficiency. The sensor is lightweight, durable, and mounts discreetly to your bike´s chainstay, with a powerful magnet attaching to your crank arm to provide accurate readings on every single rotation.Key Benefits:* Optimize Your Training: Use precise RPM data to structure your workouts, maintain consistent effort, and track your progress over time.* Improve Pedaling Efficiency: Learn to maintain a higher, smoother cadence to conserve energy, reduce muscle fatigue, and increase your overall speed.* Interference-Free Performance: The digitally coded STS wireless protocol guarantees a rock-solid connection, eliminating data corruption from other sensors or power lines.* Easy Installation: The set includes all necessary mounting hardware for a quick, simple, and tool-free installation on your bicycle.Main Features:* Accurate and reliable cadence measurement (RPM)* Digitally coded STS three-channel wireless transmission* Low battery indicator on the head unit* Automatic pairing with compatible SIGMA computers* Water-resistant design for all-weather reliability* Lightweight and aerodynamic profileCompatibility:This Sigma cadence sensor STS Set is the perfect upgrade for a wide range of SIGMA bike computers.
