BC 12.12 STS only

Digitally coded triple wireless transmission

STS stands for SIGMA TRANSMISSION SYSTEM. This interference-free digitally coded transmission system is used for all data from the speed, cadence, and heart rate transmitters.

The transmitters collate their signals and send the data package to the receiver integrated into the computer head. The transmitters also regularly send stored test data for data comparison purposes.


PC & MAC ready

SIGMA DATA CENTER evaluation software

Every model in the TOPLINE 2012 range can be connected to a PC or MAC using the optionally available docking station.

The SIGMA DATA CENTER evaluation software can be used to program the bike computer on your home computer and evaluate ride and training data. The software can also be used without the docking station. The data from the last ride can be manually entered and then evaluated in detail.
