This is Garmin's latest cycling computer. It is loaded with features and is the winner of our Top Pick Award for Strava addicts and racing. It has many parallel functions to the Garmin Edge 810 but lacks the touchscreen and routable maps of our Editors' Choice Award winner, the Edge 820. The Edge 520 is loaded with features, including Strava Live, which gives you real-time data on how close you are to stealing that KOM.
Like the 820 and its predecessor the 510, data uploads can be accomplished using the Garmin Connect Application. However, the 520 takes connectivity to the next level with Bluetooth 4.0, which allows you to get calls, text, and email updates sent to the device from your phone. If you are looking for the most advanced training tool available, with the added benefit of connectivity features, then the Edge 520 is the cycling computer for you.
