The SIGMA DATA CENER includes the following: display of total values in table format, 7-trip memory with trip data comparison, and other software functions including battery status, syncronization manager, remaining log memory available, print all evaluations, ability to mange more then one ROX cycle computer, and set up the bike computer via PC. Graphical illustration of saved logs details analysis of the trip includes a heart rate pie chart.


The STS Sigma Transmission System features digitally encoded 3-channel wireless transmission. Speed, cadence, and heart rate are sent in digitally encoded data packages to the receiver integrated inside the computer head. Shorter transmission intervals guarantee faster screen updates, providiong more accurate (near real time) ride data.


IAC Intelleigent Altitude Calibration offers 3 calibration methods including by ciurrent altitude, by starting altitude, and by air pressure at sea level.


The reduction of the transmission time, the energy rest mode, and the use of CR2450 3V batteries enable a battery life span of at least one yEAR for the computer.


The computer automatically recognizes 2 programmable wheel sizes with only one transmitter. The ROX speed transmiitter can be set as BIKE 1 or BIKE 2 with a press of a button.


The function overview reflects 7 bike functions (i.e. automatic bike recognition), 3 cadence functions, 7 time functions, 9 heart functions, 6 altitude functions, 9 uphill functions, 8 downhill functions, 2 favorite functions, 10 total values, 3 temperature functions, 10 PC / memory functions, 11 general functions (i.e. tool free mounting), and 11 software functions (i.e. easy pre-setting and simple menu guide, automatic function scan, and watertight).
