SIGMA R2 Duo Combo Speed and Cadence Sensor | ANT+ & Bluetooth

Unlock your full cycling potential and elevate your training with the SIGMA R2 Duo Combo Speed and Cadence Sensor. This essential piece of electronics is designed for dedicated cyclists who demand precision, reliability, and seamless connectivity. By capturing both your speed and pedaling cadence simultaneously, the R2 Duo Combo provides the critical data you need to analyze your performance, optimize your efficiency, and achieve your fitness goals. Move beyond basic GPS tracking and gain a deeper understanding of your effort on every ride, whether you´re climbing a steep mountain pass, sprinting on the flats, or training indoors.

The primary benefit of the R2 Duo Combo lies in its powerful dual-data transmission from a single, streamlined unit. This intelligent sensor provides real-time speed and cadence metrics, allowing you to maintain a consistent and efficient pedal stroke while accurately tracking your velocity. This data is invaluable for structured workouts, helping you stay within specific training zones and preventing over-exertion or inefficient "mashing" of the pedals. Its robust, magnet-based system ensures rock-solid accuracy and reliability, free from the signal dropouts that can affect GPS-only speed measurements in tunnels, dense forests, or urban canyons.

Key Benefits:

* Comprehensive Performance Data: Train smarter by monitoring both your speed and cadence in real-time. Understanding the relationship between these two metrics is the key to improving pedaling efficiency, increasing power output, and reducing fatigue over long distances.
* Universal Connectivity: Featuring both ANT+ and Bluetooth Smart (BLE) transmission protocols, this sensor offers maximum compatibility. It connects flawlessly to a wide range of devices, including SIGMA bike computers like the ROX GPS 11.0, as well as third-party head units from Garmin, Wahoo, and others. It also pairs directly with your smartphone or tablet for use with popular training apps like Zwift, TrainerRoad, Strava, and the SIGMA RIDE app.
* Reliable and Accurate Measurement: Unlike standalone GPS, the magnet-based speed sensor provides unerring accuracy regardless of satellite signal strength. The cadence meter gives you precise feedback on your pedaling rhythm, helping you develop a smoother, more powerful, and less injury-prone technique.
* Simple, Secure Installation: The R2 Duo Combo is engineered for a quick, tool-free installation on your bike´s chainstay. The secure mounting and proven magnet system ensure it stays in place and delivers consistent data, ride after ride.

Main Features:

* Dual Transmission Technology: Equipped with both ANT+ and Bluetooth for broad compatibility with bike computers and smart devices.
* Combined Speed and Cadence Measurement: A single, efficient transmitter captures both critical cycling metrics.
* Magnet-Based Sensor System: Delivers highly accurate and uninterrupted data for both speed (via a spoke magnet) and cadence (via a crank magnet).
* Water-Resistant Design: Built to withstand the elements with an IPX7 rating, ensuring reliable performance in rain and wet conditions.
* Long Battery Life: Powered by a common and easily replaceable CR2032 coin cell battery for many hours of training.
* Lightweight and Aerodynamic: Its slim profile minimizes weight and air resistance on your bike frame.

These advanced Sensors and Cadence meters are the perfect upgrade for any cyclist looking to transform their ride from a simple commute into a data-driven training session.

* For ROX GPS 11.0 (and other ANT+/Bluetooth Smart compatible devices)
* Data Transmission: speed/cadence (ANT+/ Bluetooth Smart)

Questo sensore ha il protocollo di collegamento con altri dispositivi (ANT+/ Bluetooth Smart), quindi, molto probabilmente, lo potrai usare anche con il tuo Garmin, perchè anche lui avrà lo stesso protocollo di collegamento con altri dispostivi.

Is it adapted for sigma rox 4.0

petro Moretti

I wonder if this combi sensor is enough for speed and cadence and if it is water resistant and delivers data to rox 4.0

Answer of Grazia

Yes, it is good for speed and cadence, and it is water resistant. As a connection mode, I use ANT + / Bluetooth Smart, so if the Rox 4.0 has these modes, it will connect easily.
