The Sigma R1 Duo Heart Rate Strap is a must-have accessory for any serious cyclist. Made from durable plastic and featuring a comfortable textile band, this heart rate monitor is designed to provide accurate and reliable readings during even the most intense workouts.
Using Bluetooth technology, the pulse transmitter sends data to your smartphone or other compatible device, allowing you to track your heart rate in real-time. The light, flexible, and adjustable strap ensures a comfortable fit, while the laminated electrodes provide better and more accurate pulse measurement.
With a measurement range of 30 to 240 beats per minute, the Sigma R1 Duo Heart Rate Strap is suitable for athletes of all levels. The band also sends battery status information to the app, and has a battery life of up to 1.3 years (adjusted to measure every 1 second, for 1 hour of training per day). Plus, with water resistance up to 3 ATM and an ANT+ speed sensor, this heart rate monitor is built to withstand even the toughest conditions.
What sets the Sigma R1 Duo Heart Rate Strap apart from other heart rate monitors is its ability to measure the RR interval in milliseconds, which is a measure of heart rate variability. This feature allows you to track changes in your heart rate over time, providing valuable insights into your overall cardiovascular health.
