The Edge 305 with cadence includes a self-calibrating, wireless speed/cadence sensor so you can monitor your pedaling cadence as you ride. Like the heart rate monitor, the speed/cadence sensor uses the same robust ANT wireless technology to reliably measure and report your pedaling strokes per minute to the Edge.
