Debutant of 2025 in the Sigma brand lineup is a flagship bike computer with an extended package. The model is capable of attracting demanding cyclists, including professional racers. Along with the model, in addition to the usual wheel rotation sensor, additional accessories are included, namely a cadence sensor (determines pedaling frequency) and a chest heart rate monitor (measures pulse during training).
Information from these components is displayed in real-time on a 3-inch touchscreen color display. Also, the Sigma Rox 12.1 Evo Sensor Set bike computer features a GPS module that allows you to plot and change travel routes non-stop without using a phone, receive voice navigation prompts, find the nearest way home, etc. Other equipment features include a memory card slot, Wi-Fi and Bluetooth wireless modules (for connecting to a computer or smartphone), and ANT+ (for syncing with other sports equipment).
Interesting features include compatibility with e-bikes and profile trainers, easy data transfer to services like Strava or TrainingPeaks, plenty of useful notifications, including fall detection, reminders for water or food consumption, and more. The model is powered by a battery that provides up to 14 hours of autonomy. It is also worth highlighting the decent sealing of the body (compliant with the IP67 standard).
