The Sigma Pure GPS provides you with the most important bike functions. The integrated GPS tells you exactly how fast you're biking and what the distance traveled is. In addition, the bike computer features an air pressure sensor that you can use to view your route's height profile. Thanks to the compass, you can see which direction you need to take. After your bike ride, view your data on your smartphone via the Sigma Link app and share with your friends. You can easily operate the bike computer using the 3 buttons, and you can read the data on the screen at a glance.
