Your Sigma Rox 10 communicates via the ANT+ radio standard. To help you get the most out of your Rox on a second bike, or to purchase replacement parts, Sigma offers the speed sensor, cadence sensor and heart rate chest strap as separate components. The Sigma ANT+ heart rate chest strap with comfortable textile band precisely monitors your heart rate under your jersey. The ANT+ radio signal sends the data directly to the Rox 10 in front of you, enabling you to precisely control and modulate your training load at any time.
