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.

Stay Tuned: Smart notifications connect you to the outside world even when you're riding. Notifications of incoming calls and messages to your smart phone appear on your display.

Great quality Cabin and air filter bundle pack. Very solid quality.
Size: 18-22 1.5L, Size: 18-22 1.5L
First off, I like that it's a combo pack instead of me having to buy each one individually and being able to change both at the same time. Now, I must say the quality of both of them is fantastic; I'm really impressed. It's not made out of cheap junk; it feels solid and seems like it will do a good job filtering out all the debris and dirt. It was extremely easy to install and fit perfectly like an OEM air filter and cabin air filter on my Honda Accord. The cabin air filter is definitely a solid piece, and you don't have to worry about it getting crushed or deforming as it's padded, I would assume the reason for the padding on the side of the cabin air filter is that no debris or dust sneaks through which gives it a snug fit which is very smart honestly. The same applies to the air filter that goes under the hood; it definitely feels like a quality piece. A quality filter definitely keeps outside odors and smells from coming inside the cabin, allowing you to get fresh, clean air when you turn your AC on. Overall, definitely a solid purchase, and I will definitely be back to buy this exact bundle pack in the future as it's well-built and fits like a glove. So, you're definitely getting great value for your money with this specific engine and cabin air filter combo pack. There are a lot of garbage ones out there, so if it were flimsy and felt like a cheap filter, I would be giving this one or two stars. But I'm actually quite impressed with this company, and it seems to be doing a fine job. My AC does work better after installing these new filters, and of course, the car runs better with the air filter installed.

Good Fit & Quality
Size: 14-22 2.0L hybrid, Size: 14-22 2.0L hybrid
This set which includes both the engine and cabit air filters are of good quality and fits my 2020 Honda Accord Hybrid well. The engine filter feels sturdy and well built. The cabin filter, although without charcoal infusion, has many folds which is more important when it comes to effective filtering of particles. The installation was easy and for the set, this set offers a good value.
