Product Information
Full details
The Sigma ROX Duo Speed Transmitter is designed for cyclists using Sigma ROX 4.0 or ROX 11.1 EVO bike computers who want to enhance their ride data accuracy. It allows seamless connection to external speed sensors via ANT+ or BLE, providing precise real-time information. A key benefit is the expanded data collection for deeper performance insights, though its primary function is speed, it does not measure other metrics on its own.

FAQs
Do I need a separate sensor for cadence or heart rate?
Yes, the Sigma ROX Duo Speed Transmitter is primarily for speed measurement. You will need separate compatible cadence and heart rate sensors to track those metrics.
What type of battery does the sensor use?
The sensor typically uses a standard CR2032 coin cell battery. Please refer to the product manual for exact specifications.
Can I use this sensor with other brands of bike computers?
While the sensor uses standard ANT+ and BLE protocols, it is officially designed and tested for compatibility with Sigma ROX 4.0 and ROX 11.1 EVO computers. Compatibility with other brands may vary.
How do I know when the battery needs replacing?
Your Sigma ROX bike computer will usually display a low battery indicator for connected sensors. You may also notice intermittent connection or inaccurate readings as a sign of a low battery.
Is the sensor waterproof?
The sensor is designed to withstand typical weather conditions encountered during cycling, including rain. However, avoid submerging it in water.
Can I connect it via both ANT+ and BLE at the same time?
The sensor typically broadcasts on either ANT+ or BLE, and your bike computer will connect using one of these protocols. It does not broadcast simultaneously on both to two different devices.
Troubleshooting
Speed sensor not detected by bike computer
Ensure the sensor is correctly mounted and the wheel is spinning. Verify that your ROX bike computer is in sensor search mode and that ANT+ or BLE is enabled. Check the sensor's battery and replace if necessary.
Inaccurate speed readings
Confirm the sensor is properly aligned with the bike computer's receiver. Ensure there are no other strong wireless signals interfering. Check that the wheel circumference is correctly set in the bike computer's settings.
Connection drops intermittently
Check the sensor's battery level. Ensure the sensor is securely mounted. Minimize potential sources of wireless interference. Try re-pairing the sensor with your bike computer.
