Garmin Varia RTL315 GPS Computer

Garmin's Varia RTL315 GPS computer offers cyclists invaluable peace of mind by detecting approaching vehicles from behind up to 140 meters away. The clever rear-view radar seamlessly pairs with a bike computer, smartphone, wearable or the included display unit to provide alerts that help you keep an ear out for traffic. When used with the Varia app on your phone, graphics and vibration alerts make it easy to identify when cars are coming up from behind. The vertical design neatly mounts to most road bikes so you can focus on the road ahead, not what's lurking up behind.
