Our sensations

After using it, it seems to us a perfect device for those who want to start having control of their data in real time from the bicycle or who want to do routes or cycle tourism.

In the box, there are two accessories to place it on the bike, Butler on the stem and another with the classic mount on the handlebar or stem

In terms of ease of use, it is simple, although it takes a while to learn how to use it, but like all SIGMA products, it is a safe bet.

It is also compatible with other sensors such as Cadenciometer, HR meters, speedometers.

As for the cons that we have found, you can only connect to Strava, Komoot, Training Peaks but not to a service like Wikilock.
