The legendary Garmin Edge 520 features seamless Strava integration for segment alerts, live-tracking and instantaneous data. Features include a V02 max estimation tool, Bluetooth 4.0 integration and the ability to upload downloadable workouts or race courses via Garmin Connect®. Classic features include ANT+ sensor support (power meters, cadence, speed, heartrate and more), an auto-scroll feature, up to 10 fields of data per screen and the uber-solid Garmin quarter mounting system. Whether training hard (there's a recovery tool for planning workouts), adventure-riding (detailed third-party maps are now downloadable) or attacking that next Strava KOM, the Edge 520 is an outstanding high-tech addition to your cockpit. This unit is only about 6 months old and in excellent condition. Everything works as it should and the battery holds a full charge as new. Includes USB charging and a new Out Front Mount with full accessories (camera mount, light mount, handlebar adapters). Buy this one and save $100 off buying new.
