The Sigma ROX 12.1 Evo GPS bike computer with powerful navigation functions

The ROX 12.1 Evo GPS bike computer from Sigma offers map navigation and training functions in a compact, lightweight design. The transflective display is easy to read even in sunlight. Thanks to the intuitive operation with buttons and touchscreen, you can navigate through the menu without any difficulty. Six individually adjustable training pages show you exactly the data you need. You can choose from six pre-installed sport profiles and 20 additional configurable ones. This way, you can choose the right settings depending on your bike type, whether gravel bike, road bike, mountain bike or indoor trainer. The computer is also suitable for e-bikes. If you have an electronic groupset, you can also access its data and see, for example, your current gear gradation. In combination with the Ride App, you can analyse your training data in even more detail, receive smartphone notifications and share your rides on e.g. komoot or Strava.

Map Navigation
To get to your destination, you have several options to choose from. But no matter whether you enter an address or coordinates to find a destination, search for a point of interest, choose from your most recent destinations or favourites, or simply freely select a point on the map, the computer creates the optimum route according to your settings. You always remain flexible and can, for example, add or skip stops. If you deviate from the route, it will be recalculated. By default, your location is the starting point. If you are planning a route for your holiday, it is also possible to specify a different starting point. You can be navigated to the starting point or the nearest waypoint of a planned track or, if you are already on your way, back to the starting point along the same route. A unique navigation feature with an element of surprise is the Draw-my-Route function. The ROX 12.1 Evo creates a route from a hand-painted line on the map. This can be saved as a track or started directly. When creating the route, there are always three options to choose from. You can choose between the easiest, recommended and shortest route. Preferences regarding the type of tracks (cycle paths, roads, unpaved tracks) are defined beforehand in the sport profile.

Six pre-installed and 20 configurable sport profiles allow you to tailor your training to the bike you are riding. Up to six screens can be freely set on the computer. Depending on how many values are to be displayed per page (1-10), you will receive different layout suggestions, with 8 different field colours for highlighting to choose from. A total of 30 training views are available, as well as additional views for workout, FE-C smart trainer and laps. In order to collect further data, the training computer can be paired with various sensors to determine cadence, heart rate or similar. For training analysis, the computer offers various statistics and shows your personal records. For more detailed analyses, simply connect it to the Ride app.

E-Bike Ready
The bike computer is e-bike ready. This means that you can connect it to most e-bikes. This gives you values such as range, battery status and support level on the display of your bike computer.

Electronic Shifting
If you use an electronic shifting system, your bike computer allows you to keep an eye on the battery charge status, the front and rear gears, the gear ratio and, in the case of Di2, the shifting mode. When used with Shimano Di2, you operate the computer using the D-Fly channel and switch between the training pages without taking your hands off the handlebars.

Trend Indoor Cycling
Your cycling computer can be connected to smart trainers. This gives you access to all computer functions to record your training.
