GPS bike computer Sigma ROX 4.0 GPS HR set with overclamp Butler handlebar mount - white

GPS BIKE COMPUTER WITH ALTITUDE MEASUREMENT
The ROX 4.0 GPS supports you on your bike tour with 30 functions and user-friendly controls, allowing you to focus on what is important: enjoying biking. The extra-large display reliably shows data such as altitude profile, speed, distance, and training time. The ROX 4.0 bike computer also shows navigation information and connection to an e-bike and external sensors as a matter of course!

LARGE DISPLAY
The 2.4-inch-diagonal high-contrast display and extra-large numbers make it easy to read, even during a ride.

RED CIRCLE
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.

EVERYTHING AT A GLANCE
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.

READY TO GO ANY TIME!
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 speed, heart rate, and cadence.

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.

PERFECTLY POSITIONED
The Overclamp Butler enables you to perfectly align your ROX 4.0 bike computer, even if you have a short stem. The computer head can thus be positioned centrally above the stem at the level of the handlebars. This ensures that there is space and order on your handlebars and that you have a good overview of all values, even if you’re not riding a mountain bike. The Butler fits on handlebars of 31.8 and 35 mm diameters.

THE CLASSIC
The classical SIGMA GPS handlebar bracket can be fixed in place without tools in a few seconds with two cable ties. This gives you a choice between installation on your handlebars or on the stem, and the device fits handlebars of all sizes.

UP WHERE THE AIR IS CLEAR
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.

PIONEER
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. It can be displayed either as an arrow on the display or inside the Red Circle. This circle on the display is highlighted in red and shows the distance to upcoming turn-offs as coloured bars that get shorter as the turn-offs get nearer. The number of metres to the next turn-off is also displayed next to the circle.

E-BIKE-READY
You ride an e-bike? No problem. The ROX 4.0 is e-bike-ready and can be easily connected to many e-bikes. Your GPS bike computer establishes a connection to the compatible e-bike system and shows you the current assist mode, battery status, and light and other data on the display. You can use this list to find out if your E-BIKE is compatible with the ROX 4.0.

BEST MEASUREMENTS
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. You can find accessories sets with various sensors for your ROX in our shop.

FOR DATA COLLECTORS
You can use the SIGMA RIDE app to collect your training data, transfer them to your smart phone via BLE, and quickly set your favourite display views on your smart phone. The most important data and statistics can be read from your smart phone in real time with the SIGMA RIDE app’s LIVE function and assessed conveniently.

SMART FUNCTIONS

BE THERE LIVE
Record your data with your bike computer and analyse them right away with the SIGMA RIDE app’s LIVE view. You can set your individual display views extremely easily while you’re riding.

STAY TUNED
Smart notifications connect you to the outside world even when you’re riding. Notifications of incoming calls and messages to your smart phone appear on your display.
