* With high quality batteries and 1 hour use per day or 4536 mi year at 12.43 mph average speed (batteries available from SIGMA SPORT®) 

** optional with ROX 10.0 GPS without transmitter 

*** The ROX® 10.0 comes with two options for displaying the power. Option 1 (formula): Calculation of the power from the system weight (cyclist + bike), wind resistance, incline, speed, and cadence (cadence transmitter required) data. Option 2 (ANT+ power meter): Measurement of the power using an ANT+ power meter from another manufacturer (e.g. SRM etc.)
