Digitally encoded three-channel wireless transmission

The tried-and-tested SIGMA TRANSMISSION SYSTEM (STS) is the digitally encoded transmission system for all transmitter data from the speed transmitter, the cadence transmitter, and even the heart rate transmitters for the high-quality basic devices and top models. The transmitters collate the data they have received and send this to the receiver integrated into the computer as a data package. The transmitters also regularly send stored test data for data comparison purposes.

The digital encoding of the SIGMA TRANSMISSION SYSTEM prevents transmitter data from being corrupted by external interferences such as power sources or other transmitters. The interference of Sigma products, e.g. LED lights, can also be prevented.

STS Sender

New STS transmitter

The STS‐speed and cadence transmitters now pivot to easily align with the magnets. The battery compartment of the STS‐speed transmitter is located on the outside of the transmitter, making it possible to change the battery while mounted.

When using the cadence transmitter, you get both the current and average cadence measurement.



Or as we like to call it, a smart backlight. Press the Alti button and the Menu button at the same time to activate the backlight. Once activated, each time you press a button, the backlight will illuminate. When the computer goes into sleep mode, the backlight automatically deactivates.


Watertight in accordance with IPX8

The BC 14.16 STS is waterproof according to the international standard IPX 8. This means there is "protection against permanent immersion". Nothing stands in the way during the next ride in the rain.


Two new spoke magnets (standard and power) are equipped with a one‐piece click‐mount clamp. Installation is easier than ever. Magnets can be installed and removed without tools.



Cadence magnet

The new cadence magnet can be attached directly to the pedal spindle without additional aids. Since it is very thin, the risk of making contact with the transmitter is low, even in tight spaces. In the event of a large gap between the crank and the transmitter, or when used with non‐magnetic pedal axles, two plastic magnet holders are included.
