The Garmin Edge 520 GPS with Heart Rate Monitor and Cadence Sensor is the next generation in Garmin GPS. Here’s the competitive edge you’ve been waiting for. Edge 520 is the first device with Strava live segment challenges. This aerodynamic GPS bike computer is packed with advanced analysis features like time in zone, cycling-specific VO2 max1 and recovery time, indoor trainer support, cycling dynamics and in-ride challenges through Strava and Garmin Connect segments. Coming with a Heart Rate Monitor (HRM) and a Cadence Sensor you are able to keep a live feed of your performance levels, egging you on to go that bit faster or spin that little bit more. The 520 Edge will store the data from the two external monitors/sensors and feed them onto Strava or you’re preferred and compatible cycling platform.
