The ROX 4.0 has over 30 functions offering all the data you need such as altitude profile speed distance and training time. The outstanding 2.4 inch display is very easy to read even when the bike is moving. A genuine highlight of ROX 4.0 is the integrated air pressure sensor that uses barometric readings to determine inclines and declines. Providing you with reliable information about altitude and generating a precise record of your route. ROX 4.0 shows navigation and can automatically connect with your e-bike and external sensors for measuring speed heart rate and cadence.

Large Display: The 2.4-inch-diagonal high-contrast display and extra-large numbers make it easy to read even during a ride.

Red Circle: The innovative Red Circle on the upper right corner of the display is highlighted in various colours and offers innovative interesting display of training data.

Everything At a Glance: The SIGMA RIDE app allows you to set your display view individually. You can set up to six views each with three values. Current speed and time are shown continuously on the display.

Ready to go Any Time: The ROX 4.0 bike computer can be positioned directly on the handlebars in a few easy steps- entirely without cables or sensors. If you want you can connect your Rox 4.0 to additional sensors for measuring speed heart rate and cadence. Your ROX uses GPS and GLONASS to determine your position within a few seconds of being switched on. The user-friendly operation with three buttons enables you to start a bike tour right away. You can use the SIGMA RIDE app to set your individual display views.

Perfectly Positioned: The Overclamp Butler enables you to perfectly align your ROX 4.0 bike computer even if you have a short stem. The computer head can thus be positioned centrally above the stem at the level of the handlebars. This ensures that there is space and order on your handlebars and that you have a good overview of all values even if you're not riding a mountain bike. The Butler fits on handlebars of 31.8 and 35 mm diameters.

The Classic: The classical SIGMA GPS handlebar bracket can be fixed in place without tools in a few seconds with two cable ties. This gives you a choice between installation on your handlebars or on the stem and the device fits handlebars of all sizes.

Up Where The Air Is Clear: A true highlight of the ROX 4.0 is the integrated air pressure sensor. It uses barometric readings to determine inclines and declines and provide you with reliable information about altitude allowing a precise recording of your track. You can also call up a graphical altitude profile on the ROX 4.0. The home altitude at the beginning of the tour is determined automatically from GPS or you can set altitude manually.

Pioneer: Connect your ROX 4.0 with your komoot app and leave your smart phone in your pocket. Receive turn-by-turn navigation from the komoot app on your ROX 4.0. It can be displayed either as an arrow on the display or inside the Red Circle. This circle on the display is highlighted in red and shows the distance to upcoming turn-offs as coloured bars that get shorter as the turn-offs get nearer. The number of metres to the next turn-off is also displayed next to the circle.

E-Bike-Ready: You ride an e-bike? No problem. The ROX 4.0 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 the current assist mode battery status and light and other data on the display. You can use this list to find out if your E-BIKE is compatible with the ROX 4.0.

Best Measurements: Do you need more data or even greater accuracy for your values? ANT+ and BLE enable you to connect external sensors such as speed heart rate and cadence sensors to your ROX 4.0. You can find accessories sets with various sensors for your ROX in our shop.

For Data Collectors: You can use the SIGMA RIDE app to collect your training data transfer them to your smart phone via BLE and quickly set your favourite display views on your smart phone. The most important data and statistics can be read from your smart phone in real time with the SIGMA RIDE app's LIVE function and assessed conveniently.

Be There Live: Record your data with your bike computer and analyse them right away with the SIGMA RIDE app's LIVE view. You can set your individual display views extremely easily while you're riding.

Saved my neck and my desk space! Solid and stylish
Color: Walnut, Size: 42.5 Inch
I’ve been looking for a way to raise my dual 27-inch monitors, and this Fenge stand is perfect. The 42.5-inch length is exactly what I needed—both monitors fit with room to spare. It’s raised them to the perfect ergonomic height, so no more neck strain! The wood finish looks much more expensive than it actually is, and the storage space underneath is a lifesaver for hiding my docking station and keyboard when I'm done for the day. It feels very sturdy and doesn't bow in the middle at all. If you want a clean, organized desk, this is the way to go.

Decent Stand with Lots of Storage Options
Color: Black, Size: 42.5 Inch, Color: Black, Size: 42.5 Inch
Received this stand today and am very pleased. I was able to put it together in about 15 minutes . I had no issues during assembly other than that my box was missing the instructions; luckily they were relatively easy to find online when searching the brand on google. Now for the price range, this is a great bang for your buck as far as monitor stands go. It has nice heavy duty metal legs and the built in phone stand is a nice touch, but I do wish the the stand itself was made of solid wood as it does feel like cheap particle board that may or may not bow over time depending on how much weight you put on it. It's not as cheap feeling as many other stands on Amazon but I do think it would benefit tremendously if it was built with real wood. Because it has (2) shelves, one of the best things about this stand is how many places it has to store items, setup docking stations, laptops, or even small music interfaces including under the bottom shelf. However, I think that the center cubby should've had an opening in the back to allow cords/cables to pass through which would've made this stand even more versatile, the only way around that issue is to drill a hole through the back panel but at least it will be pretty hidden and not visible from the front. All in all, I'm happy with my purchase and think the pros outweigh the cons. It tidied up my desk's overall look, has (2) wide shelves, and overall sleek/modern design all for $100 makes it worth it. I would definitely buy it again but hope they improve on the shelf material, even if it does increase the price slightly.

As good as you hope it is!
Color: Walnut, Size: 42.5 Inch
I'm really happy with this stand! It perfectly well made, all the holes line up, the legs are made of metal, it's very sturdy, and the instructions were easy to follow! The stand sits on my desk perfectly flat and the wood print veneer looks good. I would recommend this stand to friends and family without hesitation.

Good, would recommend
Color: Walnut, Size: 42.5 Inch, Color: Walnut, Size: 42.5 Inch
My favorite feature is the shelf that sticks out with a ledge for phones and tablets. It feels like an elegant design and I appreciate being able to use my iPad as a second screen for my Mac mini and/or as a sort of office dashboard. The wood is mdf with veneer, so not the best materials. And I was a little disappointed with the wood tone, which leans cooler/grayer than my desk. But the tone isn’t misrepresented in the listing, it’s just not prominent. And I don’t notice once it’s on my desk and loaded with various tech. It actually blends in really well and matches my black on wood aesthetic. The legs are a really cool design too. Overall very pleased, and $90 is within the realm of reason. If you want a true wood cockpit-style riser you’d have to pay $300+.

Perfect!
Color: Black, Size: 42.5 Inch
So excited about this purchase. Looks great, so easy to put together, and functional with the shelf that comes out for your phone, glasses or whatever you want to set down while you work. Makes it so your desk isn’t just flat and boring and feels more put together. Also great at hiding cables that you might have hanging off your desk. Highly recommend!
