Product Information
Full details
The Garmin Cadence Sensor 2 is designed for cycling enthusiasts and athletes who want to optimize their performance by tracking pedaling strokes per minute. This wireless sensor offers the significant advantage of an easy, magnet-free installation that works across various crank arm sizes, making it simple to transfer between different bikes. However, users should note that the device does not feature a built-in display, meaning you must pair it with a compatible head unit, smartwatch, or mobile app to view your live data.

FAQs
Do I need to calibrate the sensor?
No, the Cadence Sensor 2 does not require manual calibration; it automatically detects and transmits cadence data.
Can I use this for multiple bikes?
Yes, because the sensor is held in place by a simple silicone strap, you can easily remove it from one bike and mount it on another.
Is the sensor waterproof?
The sensor is designed to be weather-resistant and can withstand rain and road spray, though it should not be submerged.
Does this track my speed as well?
No, this specific sensor only tracks cadence (pedaling strokes). Garmin offers a separate Speed Sensor 2 for tracking speed and distance.
What battery does it use?
It uses a standard user-replaceable CR2032 coin cell battery.
Troubleshooting
Device is not detected by phone or bike computer
Ensure you have spun the crank arm at least twice to wake the sensor from its sleep mode.
Erratic or missing data during a ride
Check that the sensor is securely fastened to the crank arm and replace the battery if it is nearing the end of its life.
