SIGMA STS Speed Sensor: Precision Wireless Speed TrackingUnlock the full potential of your cycling training and analysis with the genuine SIGMA STS Speed Sensor. Engineered for cyclists who demand accuracy and reliability, this essential accessory seamlessly integrates with your SIGMA bike computer to provide flawless, real-time speed data. Whether you are a competitive athlete tracking performance metrics or a passionate enthusiast exploring new routes, this sensor is the key to precise and consistent speed measurement, ride after ride. Say goodbye to estimations and hello to data-driven performance enhancement.The core of this device is its superior transmission technology. Unlike older analog systems, such as ATS, which can be prone to interference, this sensor utilizes the advanced SIGMA TRANSMISSION SYSTEM (STS). This digitally coded system ensures a completely interference-free and robust data transfer from the sensor to your head unit. This is especially critical in environments with other electronic devices, such as group rides, urban areas, or when using multiple wireless sensors. The result is pure, uncorrupted speed data you can trust implicitly to gauge your effort and track your progress.Designed with practicality and durability in mind, the SIGMA STS Speed Sensor is built to withstand the rigors of any cycling discipline. Its robust, water-resistant housing protects the sophisticated electronics from rain, mud, and splashes, ensuring peak performance in all weather conditions. Installation is a breeze thanks to a clever, tool-free mounting system. The included flexible O-rings allow for quick and secure attachment to the fork of almost any bicycle, from road bikes to mountain bikes, without any tools or technical expertise required. The user-friendly design extends to maintenance, with an easily accessible battery compartment for quick and simple battery changes, keeping you on the road with minimal downtime. It's the perfect addition to the ecosystem of SIGMA sensors, elevating your collection of compatible speedometers to a professional-grade training tool.Technical Specifications & Package Information* Product Type: Wireless Speed Transmitter* Category: Electronics, Sensors* Transmission Technology: SIGMA TRANSMISSION SYSTEM (STS) - Digitally Coded* Primary Function: Measures and transmits cycling speed* Battery: User-replaceable CR2032 coin cell (not included)* Durability: Water-resistant construction for all-weather useA digital transmitter to transfer the speed to compatible bike computers incl.mounting material O-rings (32mm and 42mm).Compatible with the following bike computers:BC 14.16 STS/CAD, BC 16.16 STS/CAD, BC 23.16 STS, BC 12.12 STS, BC 14.12 STS Alti, BC 16.12 STS/CAD
