Strada simplicity and digital reliability, now with heart rate and cadence. The Strada Digital Wireless combines all the cycling functionality of the popular Strada Wireless computer plus the digital heart rate and cadence measurements. Using the latest 2.4GHz digital wireless speed, heart rate and cadence sensors (ISC-10 and HR-10), the Strada Digital Wireless RD430DW is now virtually interference free and features automatic sensor recognition so you can track all your rides no matter which bike you choose. The all-new detachable fabric HR sensor is designed to be more comfortable than tradition chest straps. Along with the standard cycling functions, the Strada Digital Wireless features a low battery alarm for both the computer head and sensor.
