I had a simpler model a few years back and loved it, and that was way before any GPS models started showing up everywhere. I joined that craze, but even though I like good gadgets, it never did much for me. So I went back to a now updated, excellent, and very reliable Sigma that provides all the info I really need when riding. I'm very pleased with my choice, and would recommend it to anyone who needs exactly the right and accurate info when riding.

I have used a Sigma wired bike computer for many years. It was excellent except that the sensor wires kept breaking. They are so tiny that they were extremely difficult to fix by solder. Finally I gave up and bought this wireless unit. Installation was easy and it worked perfectly right out of the box. Only two very minor issues. 1. I expected that the wheel/speed calibration would be the same as my old Sigma unit but it turns out that it was way off. Similarly, the chart specifying the calibration by wheel size was also way off. I am calibrating it by comparing distance by GPS vs. distance from the Sigma unit and tweaking the calibration factor. It was easy to get within 0.3% but I think I can get even better on the next tweak. 2. It has a temperature sensor. However, heat from the sun makes it read high making it inaccurate.Read full review

This was a replacement for my old BC 16.12 computer/head unit, which started functioning erratically (if at all), so I was already comfortably familiar with the setup, functions, etc. A perfect fit, then! 😊

Easy to install and works great!! I placed speed sensor on rear tire on a cannondale bike with 700 tires no problems at all with signal to the front handlebars.
