How it works

Touchscreen and buttons
The 2.6 in. color display at 246 x 322 pixels takes a tap, and button controls sit alongside it, reaching the same pages and menus.
Touch + buttons
Multi-band GNSS
Multi-band GNSS draws on more than one signal band from GPS, GLONASS and Galileo. Routing, ClimbPro and your recorded track all start from a more accurate position.
Daily workouts
Daily workout suggestions are event specific and follow your training load and, with compatible sensors, your VO2 max, an estimate of aerobic fitness. Garmin Coach plans also cover general fitness.
Works with your drivetrain
The Edge 840 connects to ANT+ electronic shifting and integrates with Shimano Di2 Synchro Shift. It also supports extended display, and an Edge remote or Varia remote keeps your hands on the bars.
