The Sigma ROX 4.0 GPS bike computer supports bikers on bike tours with 30 functions and user-friendly controls, enabling them to focus on what is important: enjoying biking. The extra-large display reliably shows data such as altitude profile, speed, distance, and training time. The ROX 4.0 bike computer also shows navigation information and connection to an e-bike and external sensors. Use the free SIGMA RIDE app to track your current ride data and analyze them at any time on your smart phone.- The high-contrast ROX 4.0 display's dimensions and extra-large numbers make it easy to read, even during a ride
- With the free SIGMA RIDE app for smart phones, the computer can be used to set individualised display views in just a few clicks – up to six screens can be configured, each with three values (the fourth value, current speed, is shown continuously on the display)
- The ROX 4.0 bike computer can be positioned on the handlebars in a few easy steps –there is no need to mount cables or sensors
- It uses GPS and GLONASS to determine the biker's position within seconds
- A true highlight of the ROX 4.0 is the integrated air pressure sensor – it uses barometric readings to provide bikers with reliable information about altitude and to determine inclines and declines, allowing a precise recording of the track
- The ROX 4.0 bike computer can be connected to the komoot app on your smart phone, allowing you to keep your smart phone in your pocket during the bike tour
- Turn-by-turn instructions can be shown either as an arrow on the display or inside the Red Circle
- Thanks to ANT+ and BLE, external sensors such as power meters and speed, heart, and cadence sensors can also be connected to the ROX 4.0, so those who want even more data and even greater value precision can keep an eye on all of them if they wish
- Since it's e-bike ready, your GPS bike computer establishes a connection to the compatible e-bike system and shows the current assist mode, battery status, and light and other data on the display or in the Red Circle
- The SIGMA RIDE app collects training data and transfers them via BLE from your ROX 4.0 to the smart phone

Comfy dual-mode sandals
Cute, quite comfy to walk in and love the support of the heel strap! It is not as comfy if using in slipper mode because the straps don’t keep your foot tight enough. I am usually a 8.5 but it runs slightly small so I switched up to a 9.

Nice so far.
Size: 6.5, Color: Molasses
Comfy. They were tight the first day across the toes but as I've worn them a couple times they are loosening up. The sole is forming to my foot. These are very much like Doc Martin's from the early 2000s. Not sure about quality since I haven't had them for very long.
