Sigma ROX 4.0 Cycling Computer

The SIGMA ROX 4.0 is a bike computer with GPS. This bundle includes an improved handlebar mount and a heart rate monitor. The extra large 2.4-inch display shows your speed, altitude profile, distance and training time, among other things. When you pair the ROX 4.0 with your smartphone and Komoot App, you also get Turn-by-Turn instructions during navigation. This gives you almost all the advantages of the much more expensive bike navigation systems. Compared to the ROX 2.0, this model has a barometric altimeter and the possibility of linking ANT+ or Bluetooth sensors. With the latter, you can, for example, connect a heart rate or power meter to the bike computer. The maximum battery life of 18 hours means you can go on very long rides without worrying about your Sigma running out.

Simple navigation
The SIGMA ROX 4.0 is a really smart bike computer that even has basic navigation options. To do this, you'll need to connect it to your smartphone, and use the Komote app. On this app, you turn on the navigation, and it will then send the turn-by-turn directions to the ROX 4.0. For example, in the top right corner of the Red Circle you'll see a directional arrow and the distance in metres to the next turn.

External sensors
A big plus over the ROX 2.0 is that the 4.0 supports external sensors. You can connect external sensors to the SIGMA ROX 4.0 via Bluetooth or ANT+. For example, you can link a speed or cadence meter to your cycling computer for even more insight into your training. Of course, it is also possible to connect a heart rate monitor or even a power meter to this Sigma.

Flexible mounting
The standard handlebar mount that comes with the Sigma ROX can easily be attached to any handlebar or stem with the cable ties that come with it. For an even sturdier handlebar mount, choose the Sigma ROX 4.0 HR Top Mount Set, which comes with a premium handlebar mount and a heart rate monitor.

GPS, GLONASS
GPS and GLONASS enable your Sigma computer to pinpoint your location quickly and accurately.

E-bike ready
The ROX 4.0 connects to compatible E-bike systems and shows the current pedal assist level, battery status, light and other data on the display or in the Red Circle.

Smart notifications
If your SIGMA ROX is connected to a smartphone, you will receive notifications of incoming calls and messages.

Sport profiles
The Sigma ROX 4.0 has individually customisable sport profiles and 6 customisable training views.

Barometric altimeter
With this integrated air pressure sensor, your Sigma can accurately determine the current altitude. In combination with the GPS system, this provides a very accurate altitude measurement. This way, you can see exactly how many altitude metres you have travelled during or after your ride.
