Here’s Your Competitive Edge
We started with the aerodynamic form factor of the popular Edge 500, added in-ride challenges on Strava live segments, color display, connected capabilities and advanced analysis features. The result — Edge 520, the GPS bike computer that’s right-sized for competitive cyclists and packed with the features you crave.
 
Prove Your Edge
Edge 520 is the first bike computer that’s compatible with Strava live segments with Strava premium membership. With this membership, your starred Strava segments automatically sync with the 520 for live feedback during your ride. You’ll also get alerts for segment start and finish and leaderboard rankings once you complete the segment.
 
Train on the Edge
Need some motivation to get through those lonely miles on the indoor trainer? Edge 520 delivers with a suite of training capabilities when paired with compatible ANT+ indoor trainers. Let’s say you want to train at an average power of 240 watts. Just set the target on Edge 520, start pedaling, and the trainer will automatically adjust to keep you at your target while the 520 shows your stats. You can also follow a course that you or another rider created and literally race the recorded stats, with the trainer adjusting resistance to match the elevation profile. 

Pair it with a power meter and Edge 520 offers an additional set of features, like FTP and watts/kg tracking, so you can compare yourself to others, as well as cycling dynamics. A built-in FTP test helps you establish your baseline either on the trainer or on the road. Add heart rate³ and the 520 can derive your VO2 max estimate and post-ride recovery time, which indicates how long before you should attempt another hard effort.
 
Optimized Display
Edge 520 compromises nothing when it comes to display — 2.3 inches of high-resolution color. We maximized the display so you get the most live area in relation to the compact size of the 520. You’ll also appreciate the screen clarity in all lighting conditions. 
 
The Connected Bike
Edge 520 is compatible with ANT+ sensors, including Varia bike radar and lights4, speed, cadence, heart rate, Edge and VIRB remotes and compatible weight scales. It also integrates with Shimano Di2 electronic shifting systems5 to display your current gear on the screen. Edge 520 is also compatible with ANT+ power meters, including the Vector series.
 
Smartphone Connectivity
When paired with your compatible phone and the Garmin Connect™ Mobile app, Edge 520 offers live tracking, smartphone alerts, social media sharing, weather and wireless uploads. Once your ride is complete, the data can be automatically sent to Garmin Connect, our online community where you can save, plan and share your rides.
 
Off the Beaten Path
The compact, rugged form factor and 15+ hour battery life of Edge 520 make it ideal for off-road adventures. It’s also compatible with GPS/GLONASS satellites, so you benefit from more signal options, wherever your ride takes you.
