Sigma ROX 4.0 Cyclocomputer + HR Set Black
A screen that impresses. The high-contrast display is very easy to read even on the move thanks to its extra-large dimensions and digits. The Red Circle display at the top right of the screen has a color background and offers an innovative and exciting way to view your training data or navigation instructions. In combination with the free SIGMA RIDE app for your smartphone, customised display views can be set up with just a few clicks: up to six displays with three values each can be configured. The instantaneous speed is always displayed as the fourth value.
Ready for take-off. The ROX 4.0 is easily attached to your handlebars in just a few simple steps. And all that without the need for wires or sensors. After turning it on, the ROX will determine your position within seconds thanks to its GPS and GLONASS technology. Also thanks to its intuitive three-button operation, you can immediately start your bike ride.
Altitude measurement by barometer. The integrated atmospheric pressure sensor is a real highlight of the ROX 4.0. With the help of this barometer, you'll have the most reliable information about altitude, inclines and declines during your ride, allowing you to accurately record your training. In addition, ROX 4.0 allows you to view the graphical altitude profile whenever you need it. The initial altitude at the start of the trip can be calibrated automatically via GPS or manually.
