Sigma ROX 4.0 Black / White HR Set

The cycling computer ROX 4.0 GPS with its 30 functions and easy operation will support you on your walk so that you can focus on the most important thing: enjoying your bike ride. The extra large display shows data such as height profile, speed, distance and training time. Navigation instructions and connection to the e-bike and external sensors are a matter of course for the ROX 4.0 cycle computer!

The ROX 4.0 cycling computer can be easily mounted directly on the handlebars - completely without cables and sensors. If you want, you can
connect additional sensors to the Rox 4.0 cycle computer for measuring speed, heart rate and pedaling frequency.

Immediately after switching on, ROX searches for your location using GPS and GLONASS within a few seconds.
Combined with the intuitive three-button control, you can start driving immediately.
With the help of the SIGMA RIDE application, you can set the individual appearance of the display.

The Overclamp Butler holder allows your ROX 4.0 cycling computer to be perfectly seated even on short stems. The cyclocomputer can thus be placed in the middle above the stem at the height of the handlebars. Everything is nicely organized on the handlebars and you have all the data in plain sight, not only when riding a mountain bike. The holder is intended for handlebars with a diameter of 31.8 and 35 mm.

The classic handlebar mount for SIGMA GPS navigation can be attached in a few seconds without tools using two cable straps. At the same time, you can choose whether to attach the computer to a stem or handlebars of any diameter.

The real highlight of the ROX 4.0 cycling computer is the integrated barometric sensor. Thanks to the barometric measurement, you will receive reliable information about altitude, ascent and descent, and your route will be accurately recorded. You can also view the altitude graph on the ROX 4.0 cycle computer. The altitude at the beginning of the route can be calibrated automatically using GPS or you can set it manually.

Connect your ROX 4.0 with the komoot application and leave your smartphone in your pocket. Through the komoot app, you will receive turn-by-turn instructions on your ROX 4.0. You can receive instructions in the form of an arrow on the display or inside the Red Circle. The red illuminated circle on the display counts down the distance to the next turn using a colored line. The line gets shorter the closer you are to the turn. In addition to the Red Circle, you will be shown how many meters are left to the next turn.

Do you ride an e-bike? No problem. ROX 4.0 is e-bike ready and you can connect it to many devices. Your GPS cycle computer will connect to a compatible electric bike system and start showing you the current level of support, battery status, light and other data on the display.

Do you need more data or even greater accuracy of measured values? Thanks to the ANT + and BLE functions, you can also connect external sensors to your ROX 4.0, such as a speed sensor, heart rate and pedaling frequency.

Using the SIGMA RIDE application, you can transfer your training data to your smartphone via BLE, where you can archive them, and set your favorite display look on your smartphone with lightning speed. The most important data and statistics can be displayed and conveniently evaluated in real time on a smartphone using the LIVE function in the SIGMA RIDE application.

Record data on the cycle computer and immediately analyze it on the LIVE screen of the SIGMA RIDE application. You can easily adjust your individual display appearance there while driving.

Smart Notifications connect you to the outside world even while driving. You will receive information about incoming calls and SMS messages from your smartphone on the display.
