The Red Circle counts down the distance to the next turn with coloured bars that shrink as you get closer, and the street name is shown. If you deviate from the suggested route, your ROX quickly plans a new route to the destination with an updated elevation profile, in interaction with the SIGMA RIDE app.
- TRACKS FROM THIRD PARTIES: track navigation lets you ride a planned route precisely. Create a track in SIGMA DATA CENTER or in a tour portal of your choice (komoot, Strava, etc.) and import it into the SIGMA RIDE app. You can then start your tour and ride it right away, or save it for later on your bike computer and navigate without a smartphone connection.
- PERFECTLY SHAPED IN COOL BLACK: stylish, elegant and sporty, the ROX 4.0 ENDURANCE in cool black stands out with its sleek design and looks good on any bike.
- READY TO GO AT ANY TIME: the bike computer can be mounted on the handlebars in a few easy steps, entirely without cables or sensors. If you wish, you can connect additional sensors for speed, heart rate and cadence. The ROX uses GPS and GLONASS to determine your position within seconds of switching on. User-friendly operation with three buttons lets you start a ride right away, and you can configure your display views with the SIGMA RIDE app.
- LARGE DISPLAY: the 2.4-inch high-contrast display and extra-large numbers make it easy to read, even while riding.

- UP WHERE THE AIR IS CLEAR: a highlight of the ROX 4.0 ENDURANCE is the integrated air pressure sensor, which uses barometric readings to determine climbs and descents and provides reliable altitude information for precise track recording. You can also view a graphical altitude profile. The home altitude at the start of the tour is determined automatically from GPS, or you can set it manually.
