ROX 11.1 EVO


available from Autumn 2021

GPS training computer with a broad range of functions

Whether you are trying for a best time, maintaining your fitness level, or just want to share your tours with friends and family, the ROX 11.1 EVO bike computer is your perfect training partner for indoor and outdoor training. In addition to its many training functions, the GPS bike computer offers navigation, structured workouts, and connection to external sensors. This allows you to focus entirely on your performance – the ROX 11.1 EVO does the rest. The LIVE function allows you to analyse your training data at any time with the SIGMA RIDE app.


The bike computer’s 150 functions reliably support and guide you when you are training or on a ride with your friends. The ROX 11.1 EVO delivers all data reliably and in real time. The scope of function includes tracking speed and distance with GPS, barometric altitude measurement and navigation with Track or komoot, and compatibility with e-bikes and external sensors. The integrated Crash Alert feature informs your emergency contacts if you fall off your bike. Smart notifications inform you of incoming calls and messages during your ride. Create workouts using the service of your choice and import them in FIT format into your ROX 11.1 EVO.


Your freedom knows no bounds. Four of up to 20 possible sport profiles are already pre-installed on the ROX 11.1 EVO. Create your own sport profile and use the ROX 11.1 on different bikes. Six different training views with one to six data fields can be highlighted in colour with the SIGMA RIDE app, with a configuration tailored entirely to you. This lets you keep an eye on your personal goals. Screens for komoot workout, track, and navigation are also installed. An additional data page can be called up for connected FE-C smart trainers. Connect your ROX with a smart phone and track your performances right away on the SIGMA RIDE app Live Screen.


Up to 20 different sport profiles, such as road bike and mountain bike, can be installed and called up on the ROX 11.1 EVO.


Design your personal cockpit and select individually how many and what values should be shown on your display.


The individual data fields can be highlighted in up to eight different colours, allowing a better overview and quicker readability.


How long, how fast, how high? Save up to 100 hours of riding time on your ROX 11.1 EVO to keep an eye on your values at all times. Analyse your performance quickly on the ROX 11.1 EVO or the SIGMA RIDE app’s Live Screen. After training, the SIGMA DATA CENTER is, of course, available to you on your PC or Mac. There, you can analyse your data in more detail and plan tracks. Compare your training values, check out your progress, and use the workouts to control your individual training. Use the many SIGMA RIDE app sharing options to let your friends and teammates know about your successes.


Navigation information and ride data can be very easily read on the 1.77-inch transmissive colour display because of its outstanding contrast. The display is continuously lit and adjusts automatically to various lighting conditions thanks to its ambient light sensor. Do you want your display to be brighter or dimmer? No problem! As needed, you can set ten different brightness levels. The data fields in the training view can be set as you desire and highlighted in colour. Combined with the high-contrast display and the large digits, this ensures excellent legibility.


The ROX 11.1 EVO wins over customers with its compact, modern design. It is very light at 55 grammes and fits perfectly into your cockpit. This lets you keep an eye on everything without the bike computer impairing your performance.

Two colours to choose from
The ROX 11.1 EVO is available in two colours: subtle grey or bolder white. The display is AR-coated so that it can be read easily even in the woods.


The ROX 11.1 EVO stands out with its simple, intuitive operation. The five large buttons are easily accessible, so the bike computer is extremely easy to use even when you’re wearing gloves. The simple menu navigation helps you find your way around easily, taking you right where you want to go in just a few steps. When it is started up, the device goes straight to training mode, and you can start riding. A separate menu button allows fast access to settings and functions such as workout and track navigation. The ROX 11.1 EVO emits an acoustic signal when you receive a message or a call or need to turn.


Plan a track with your friends! Create a track in SIGMA DATA CENTER or with a third-party provider of your choice and load it to the ROX 11.1 EVO. Within track navigation, you can see the right way to go. You can also set waypoints in track navigation – for special highlights or coffee breaks on your route. If you leave the track, the ROX sends you a notification and displays the shortest route back to it. The track view zooms automatically with your speed so that you are never surprised by a curve. If you leave the track, the zoom level is increased automatically so that you can always see the track and find your way back to it quickly.


Connect your ROX 11.1 EVO with your komoot app, start your tour in the app, and put your smart phone in your pocket. komoot navigation instructions are displayed on the ROX 11.1 EVO.


Are you up for some indoor training? Connect the ROX 11.1 EVO to your smart trainer or stationary bicycle trainer. This lets you use the numerous training computer features during indoor training as well.


BLE and ANT+ make it extremely easy to fluidly and reliably combine sensors that measure speed, cadence, and pulse. You can get the ROX 11.1 EVO in a set with our new magnet-free speed and cadence sensors (which are also available as accessories). Your ROX 11.1 EVO can also be coupled to your electronic switching or the power meter.

The ROX 11.1 EVO 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 specific values such as the remaining ride range, battery charge, and support level.



Record your data with the bike computer and analyse them right away with the SIGMA RIDE app’s LIVE screen. You can set your individual training views extremely easily while you’re riding or use one of the pre-programmed views.


The ROX 11.1 EVO automatically detects a fall and gives you 30 seconds to confirm that you’re OK. If there is no confirmation, the SIGMA RIDE app automatically sends an SMS to your emergency contacts and gives them your GPS data. You can also save emergency information such as blood type, name, and medication to your device. If there is an emergency, this information will appear on your display.


Smart notifications connect your smartphone to the ROX 11.1 EVO even when you’re riding. Notifications of incoming calls, messages, and e-mails appear automatically on your display. You can even read short messages directly on your ROX 11.1 EVO. If you need quiet while you’re riding, you can disable sounds or smart notifications.


Developed especially for the ROX 11.1 EVO, the Short Butler positions the ROX 11.1 EVO closer to your handlebars and in a more streamlined position than the standard GPS handlebar holder does. There nothing between you and a new best time! The Short Butler can be mounted on handlebars with diameters of 25.4 and 31.8 mm in a few easy steps. Curved handlebars? Use the 3D rubber pads to straighten your ROX 11.1 EVO.


You prefer a lower profile? Then mount your ROX 11.1 EVO with the GPS handlebar bracket. This disc can be mounted to the handlebars or stem with cable ties, and the ROX 11.1 EVO can be twisted into it and fixed in place with a single click.
