The Edge 1040 GPS is a top-notch bike computer that shows us everything from precision locations even in the densest trail systems to real-time fitness trackers calculated from our sessions. Now, we can get even more with its bundle version. In this package, we get a speed and cadence sensor that offers pinpoint monitoring of how fast we're going, the time to get there, and the efficiency of the distance between. It also includes the HRM-Dual monitor so you can keep an eye on how much blood you're pumping.
