Sigma Rox 4.0 30-Function GPS/HRM Computer

• The 2.4-inch-diagonal high-contrast display and extra-large numbers make it easy to read, even during a ride.
• The innovative Red Circle on the upper right corner of the display is highlighted in various colours and offers innovative, interesting display of training data.
• The SIGMA RIDE app allows you to set your display view individually. You can set up to six views, each with three values. Current speed and time are shown continuously on the display.
• The ROX 4.0 bike computer can be positioned directly on the handlebars in a few easy steps – entirely without cables or sensors. If you want, you can connect your Rox 4.0 to additional sensors for measuring heart rate.
• Your ROX uses GPS and GLONASS to determine your position within a few seconds of being switched on. The user-friendly operation with three buttons enables you to start a bike tour right away. You can use the SIGMA RIDE app to set your individual display views.
• A true highlight of the ROX 4.0 is the integrated air pressure sensor. It uses barometric readings to determine inclines and declines and provide you with reliable information about altitude, allowing a precise recording of your track. You can also call up a graphical altitude profile on the ROX 4.0. The home altitude at the beginning of the tour is determined automatically from GPS, or you can set altitude manually.
• Connect your ROX 4.0 with your komoot app and leave your smart phone in your pocket. Receive turn-by-turn navigation from the komoot app on your ROX 4.0.
• Do you need more data or even greater accuracy for your values? ANT+ and BLE enable you to connect external sensors such as speed, heart rate, and cadence sensors to your ROX 4.0.
