Product details
The first basic model of the Sigma Sport Topline now features five altitude measurement functions. A must-have for anyone looking to reach new heights while keeping an eye on classic cycling functions.
IAC Altitude Calibration
The IAC (Intelligent Altitude Calibration) developed by Sigma Sport allows for three different methods of altitude calibration: calibration based on the current altitude, using three starting altitudes, or based on air pressure reduced to sea level. In standby mode, the altitude measurement is "frozen" and resumes the last saved altitude in active mode. This prevents unwanted altitude changes due to weather conditions.
All Topline bike computers are PC-compatible via an optional docking station. The optimized operating concept allows for easy adjustment of the computer and switching of function displays even while riding. Enhanced readability is provided by the large and well-structured display. The automatic start/stop function is activated by a magnetic impulse from the speed sensor. The device switches to standby mode after five minutes of inactivity or no button presses. Since the battery is not installed at the time of sale, it retains 100% of its capacity, resulting in an extended battery life.
