The ROX 9.1 offers not only all the functions of the 8.1 but also a LOG function with an expanded memory capacity of 90 h and comprehensive trip data evaluation options. In addition to displaying the speed, heart rate, altitude, slope, rate of ascent and temperature, this multi-purpose computer also provides a graphical representation of the performance, cadence and expansion. The GHOST RACE function, which can be used to race a route against yourself in real time, is a particular highlight. Includes the docking station and SIGMA DATA CENTER. General Functions: Full text display in 5 languages, Two wheel sizes adjustable, Automatic recognition of second bike, Automatic start/stop, LCD backlight, Battery status display receiver/transmitter, Ability to switch alarm on/off, Adjustable alarm volume, Watertight, Bracket for handlebars and stem, Memory back-up function when changing a battery (overall and set values).
