BIKE-OPTIMIZED MAPS Your ROX 12.1 EVO comes with many pre-installed country maps. So you can get started as soon as you unpack your bike computer! A SIGMA-only proprietary map display ensures that you can find your way around. The maps highlight bike paths and trails to always take you to the best route, no matter where you are or what bike you are using. The compressed maps require little storage, so you can store a number of areas around the world permanently. More maps and regular updates can be downloaded via WiFi free of charge so that you always have the perfect track anywhere.
INNOVATIVE MAP NAVIGATION Simply enter an address or routing to a point on the map or a point of interest (POI) the navigation possibilities are limitless. Your ROX 12.1 EVO uses home navigation to always find your quickest way home. The Back-to-Start function takes you back to the beginning of your ride ? on the same route if you want. The multifaceted navigation functions can be used independently, of course, without your ROX being connected to the internet or a smart phone.
YOUR ROUTING You decide for yourself which criteria your route should fulfil. You can choose among three route for your tour: the recommended one, the easiest, or the shortest. The altitude profile is also displayed for each route. You can also specify your route preferences (bike paths, main roads, dirt roads) individually for each sport profile.
TURN-BY-TURN NAVIGATION The map can be displayed flexibly according to your needs and offers both large and small views. During navigation, the display shows the route and turn-by-turn directions. A pop-up window with an acoustic signal tells you when to turn next. The distance to the next turn-off and the street name are also displayed.
EASY ROUTE LOADING! Route loading has never been this easy: Load routes from portals such as Strava and komoot or use a .gpx import into the SIGMA RIDE app. You can now call up your routes at any time, receive a good overview, synchronize them with your ROX 12.1 EVO, and head out. Useful Tip: in the Favourites menu, you can save your favourite tracks to call them up quickly later.
PLAN RIDES AHEAD OF TIME Your ROX 12.1 EVO enables you to plan your rides ahead of time. You can plan your next biking vacation from wherever you are your desk, your couch at home, or anywhere youre thinking about your next ride. You can then find it in your route list.
DRAW MY ROUTE A unique feature for all those who like to be surprised. Explore new routes with the unique Draw my route function. Just draw one or more lines on the map, and the ROX 12.1 EVO will create a suggested route for you. Are distance and altitude profiles what you want? Then youre ready to go!
SMART RE-ROUTING Your ROX wont let you down! If you suddenly change your ride from the suggested route, your ROX will quickly plan a new path to your destination ? including re-calculating distance, predicted arrival time, and altitude profile.
CUSTOM SPORT PROFILE Which tour and which bike will it be today ? mountain bike, gravel bike, or racing bike? The six pre-defined and 22 other customizable sport profiles make sure the ROX 12.1 EVO is prepared for any bike adventure. In the individual sport profiles, you can customize your training views, trail preferences, and alarms. The profiles can easily be created and adjusted on the ROX 12.1 EVO or in the SIGMA RIDE app ? any time, even during training.
PERSONAL TRAINING VIEWS The ROX 12.1 EVOs six training views give you maximum flexibility. You can configure them however you want and highlight the data fields with different colors. Depending on how many values you want to display (up to ten), you will get different layout suggestions. A total of 30 layouts are available. Would you like to have distance displayed instead of altitude? No problem ? you can change your training views easily during your ride. The ROX 12.1 EVO also has views for workout, navigation, FE-C smart trainer, and laps.
STRAVA LIVE SEGMENTE Use the RIDE app to load Strava Live segments to your ROX 12.1 EVO and measure yourself against other riders. Would you rather keep an eye on the track or your values while you are challenging the KOM/QOM (King/Queen of the Mountain)? You can decide!

DRINKING AND EATING ALARMS For optimum energy supply during competition and training, the ROX 12.1 EVO reminds you to eat and drink at points you determine in advance, such as at certain times or distances. You can customize another alarm with your own text ? you get to decide whether it appears only once or is repeated.
POWERMETER FUNCTIONS Powermeters have become indispensable for cycling. This training instrument enables you to measure your performance precisely for targeted improvement. In addition to general power meter values, your ROX 12.1 EVO displays specific values such as TSS, NP, and IF. It also offers you the OCA and OCP values for a Rotor 2INpower, INPower, or INSpider. In addition to the numbers, a graphical representation is available in your training view. Normalized Power (NP), Intensity Factor (IF), and Training Stress Score (TSS) are registered trademarks of Peaksware, LLC.
SMARTER GEAR SHIFTING WITH SHIMANO DI2 Your ROX 12.1 EVO is compatible with Shimano Di2 gear shifting. You can use the D-Fly buttons on the electronic gear switch to control your bike navigation system while you are riding. For instance, you can switch training screens easily without taking your hands off the handlebars.
DIGITAL REAR-VIEW MIRROR Connect your ROX 12.1 EVO to a radar and get information about approaching vehicles. The bike radar serves as your digital rear-view mirror and detects approaching vehicles, forwarding the data to the ROX in real time. This enables you to keep an eye on the traffic behind you, estimate the speed of approaching vehicles, and adjust your riding behaviour accordingly.
INDOOR CYCLING TREND Are you up for some indoor training? Connect the ROX 12.1 EVO to your smart trainer or stationary bicycle trainer. This lets you use the bike computer's numerous training features during indoor training as well. If you want, your ROX 12.1 EVO takes control of your stationary training if you are not using a Zwift.
EASY PAIRING Would you like to record other data about your training? ANT+ and Bluetooth make it extremely easy for you to reliably combine and link external sensors to measure speed, cadence, and heart rate. You can get the ROX 12.1 EVO in a set with our new magnet-free speed and cadence sensors and our chest strap (also available as accessories). Your ROX 12.1 EVO can also be paired with other sensors such as your electronic gear changes or radar:
