Speed, cadence and heart rate are sent in digitally encoded data packages to the receiver integrated inside the computer head.
Bike computer with 3-channel wireless transmission
The SIGMA ROX 8.0 answers just about all the questions you could imagine. Besides measuring altitude, inclination and temperature, the newly developed digitally encoded 3-channel wireless STS (SIGMA TRANSMISSION SYSTEM) makes it possible to use several sensors, such as pulse measurement, speed and cadence transmitter, at the same time. Analysing the individual memories and total values on the PC, however, is only possible with the optionally available SIGMA docking station and software.
