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 Sheets!
Size: Twin, Color: Oatmeal
Super soft, wash up beautifully, seem well made — very happy! It’s very hard to find 100% cotton t-shirt type sheets and these are really lovely.

Weirdly textured
Size: King, Color: Dark Gray
I have bought and loved jersey sheets in the past, that have all been as soft as a well worn cotton t-shirt. These arent soft. They have the stretch of jersey, but not the soft smooth texture that they should have. Even after washing a few times these are one of my least favorite sheets I've ever bought on Amazon.

Soft, Breathable Sheets That Feel Great to Sleep On
Size: Twin, Color: White
This Amazon Basics jersey sheet set was a really good purchase. The cotton material is soft, stretchy, and breathable — it feels like sleeping in a comfortable T‑shirt. The fitted sheet has a nice snug fit that stays in place, and the flat sheet is lightweight without feeling flimsy. The fabric washes well, doesn’t pill, and stays soft after multiple loads. It’s a great everyday sheet set for anyone who likes that cozy, relaxed jersey feel. Overall, comfortable, easy to care for, and great value for the price.

The Perfect Sheets To Lie On While Writing Amazon Reviews
Size: Full, Color: Light Gray
As I write this, I am laying on an adjustable full sized bed by Hofish and a 10.5" comfort foam mattress by Classic Brands. I know I sound like I am an Amazon plant, but I swear I am not. I'm not even a stockholder anymore. This is the most awesome bed stylings combination I have had in many, many years. In fact, it is the best I have ever owned and it is beat only by some ritzy resort I stayed at on vacation like 20 years ago, though I admit I was pretty drunk the entire time so my memory might not be the most accurate. But getting back to today... these sheets are great. I washed them twice - I'm not a neat freak, I am just amazingly disorganized and easily distracted while doing laundry, so tonight they went though two wash cycles and one dry. And then I put them on the bed. While these sheets are not deep pocket sheets, they don't need to be with this mattress. There is enough room and border for them to tuck and wrap with the elastic to give a strong grip under the mattress, which is important as the adjustable frame continually put the sheets and mattress though its repeated adjustable calesthenics-type positioning. The other two sheet sets I have used since I got this bed have struggled poorly with this. In the day or so and at least a dozen position changes, these sheets stay in place with no popped corners to exposing the bowl as the head and feet rise. Of course, till will tell if it lasts, but so far they are the best of the batch of sheets in my closet. As for texture, they are awesome. I'm a dude. I don't really know what thread count or knit or whatever really means. But these sheets feel like a well-washed favorite, quality rock & roll concert t-shirt. And not one of these glitter puff stupid new groups, like a real rock band from the 80s that now charges $250 for a concert ticket and $60 for a t-shirt...but that group you saw back then, paid $10 for the shirt and you STILL have it and love to wear it because it is perfectly molded to your body, soft and reliable. The kind of shirt you will wear under your suit at work and just grin not just for mental middle finger to corporate dress codes, but because the t-shirt is just that great of a feeling. Well, that is what these sheets feel like. And now you get to sleep in it. It is that awesome. In LA right now we are having a nasty heat wave, but these sheets don't seem to bake me even with my stuttering AC. The flannel sheets I love seem to trigger the butt sweats as soon as I lay down in this heat, but no such problem with these. So really, I'm absolutely happy with these things. I am going to order more in other colors as soon as Amazon gets them back in stock. Great price, great quality, great comfort, great fit, great deal. It is that simple.

Soft smooth and wrinkle free!
Size: King, Color: White
The most comfortable sheets I’ve had in years! Soft and don’t wrinkle up in the bed. Some reviews said they are thin but I think they’re perfect! I don’t want super thick sheets as we are hot sleepers. These are the perfect feel. They also stretch very well to fit on my mattress all the way around and I have a thick mattress! My precious sheets were a struggle to get over the corners but these fit perfectly. Would buy 10 times over! Such a good value as well!
