SIGMA ROX 4.0 Endurance GPS bike computer, White, Sensor Set

Important information before buying: the cadence, power and heart rate functions require sensors, which are not included and must be bought separately. The speed and distance functions are based on the GPS signal and are as accurate as the technology allows. Some areas may not be well covered by GPS satellites, so accuracy can vary.

Features

• Outstanding battery life: designed to withstand the longest bike adventures. Thanks to new, more efficient hardware, the battery lasts up to 41 hours, giving you plenty of time to enjoy your rides to the full.
• Search and go: navigation lets you find a specific location and navigate to it. Enter an address in the SIGMA RIDE app on your smartphone or tap a point on the map. Trail preferences (bike trails, dirt roads, paved roads and hiking trails) can be set individually. The created track can be started directly on the device or saved in the RIDE app for later.
• Re-routing and turn-by-turn directions: during navigation the display shows the track and turn-by-turn directions. A turn arrow and audible signal alert you to the next turn. The Red Circle counts down the distance to the next turn with coloured bars that decrease as you approach. The street name is also displayed. If you deviate from the route, a new route to the destination is planned in a flash together with the SIGMA RIDE app, with an updated elevation profile.
• Tracks from third parties: track navigation lets you precisely ride a planned route. Create a track in SIGMA DATA CENTER or a tour portal of your choice (komoot, Strava, etc.) and import it into the SIGMA RIDE app. Start the tour in the app right away or save it and start it later on your bike computer - navigation works without a connection to your smartphone.
• Perfectly shaped in cool black: stylish, elegant and sporty. In cool black it stands out with its sleek design and looks great on any bike.
• Ready to go at any time: the bike computer can be mounted on the handlebars in a few easy steps, entirely without cables or sensors. If you wish, connect additional sensors for speed, heart rate and cadence. GPS and GLONASS determine your position within seconds of switching on. User-friendly three-button operation lets you start a ride right away, and the SIGMA RIDE app lets you set your individual display views.
• Large display: the 2.4-inch high-contrast display and extra-large numbers make it easy to read, even while riding.
• Red Circle: the innovative Red Circle at the top right of the display has a coloured background and offers an innovative way to view your training data.
• Everything at a glance: the SIGMA RIDE app lets you set your display views individually. You can set up to six views, each with three values. Current speed and time are shown continuously.
• Reliable altitude: a highlight is the integrated air pressure sensor. It uses barometric readings to determine inclines and declines and provides reliable altitude information for precise track recording. A graphical altitude profile can be shown on the device. The home altitude at the start is determined automatically from GPS or can be set manually.
• E-bike ready: riding an e-bike? No problem. It is e-bike ready and connects easily to many e-bikes. It connects to the compatible e-bike system and shows the current assist mode, battery status, light and other data. A compatibility list is available.
• Best measurements: need more data or greater accuracy? ANT+ and BLE let you connect external speed, heart rate and cadence sensors. Accessory sets with various sensors are available in our shop.
• For data collectors: the SIGMA RIDE app lets you collect training data, transfer it to your smartphone via BLE and quickly set your favourite display views. The most important data and statistics can be read in real time with the app's LIVE function.
• Be there live: record your data and analyse it right away with the SIGMA RIDE app's LIVE view. You can set your display views very easily while riding.
• Stay tuned: smart notifications keep you connected even while riding. Notifications of incoming calls and messages appear on your display.
• Perfectly positioned: the Over Clamp Butler lets you align your bike computer perfectly, even with a short stem. It can be positioned directly over the stem, giving you more space on the handlebars and a clear view of your data. The Butler fits handlebars with 31.8 mm and 35 mm diameter.
• The classic: the classic SIGMA GPS handlebar bracket fixes in place without tools in seconds using two cable ties. Choose between mounting on the handlebars or the stem; it fits handlebars of all sizes.
