Cadence data is one of the most useful metrics for improving cycling efficiency — training to a consistent target cadence reduces muscular fatigue, improves power output, and helps you ride stronger for longer. The COROS cadence sensor makes this data available on any Bluetooth-enabled device without the need for a dedicated cycling computer.\u003c\/p\u003e\n\n\u003cp\u003eThe sensor attaches to the \u003cstrong\u003ecrank arm\u003c\/strong\u003e of your bike — a simple, secure mount that works on road, gravel, and mountain bikes, as well as most indoor spin bikes. It's \u003cstrong\u003eIP67 water-resistant\u003c\/strong\u003e for all-weather outdoor use, and the \u003cstrong\u003eCR2032 battery\u003c\/strong\u003e provides up to \u003cstrong\u003e12 months of use\u003c\/strong\u003e before replacement — a widely available, inexpensive cell that takes seconds to swap. Pairing is straightforward via Bluetooth, and the sensor works with any Bluetooth heart rate-enabled device or training app that supports cadence sensors, including Zwift, TrainerRoad, and most cycling apps. Note: this sensor uses \u003cstrong\u003eBluetooth only\u003c\/strong\u003e and is not ANT+ compatible — check your device's connectivity before purchasing.

It is not ANT+ compatible, so devices that only support ANT+ (without Bluetooth) will not work with this sensor.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhy is cadence important for cycling?\u003c\/strong\u003e\u003cbr\u003eCadence (pedalling RPM) is a key metric for cycling efficiency. Most coaches recommend a cadence of 80–90 RPM for road cycling, as higher cadences shift the workload from muscles to the cardiovascular system, reducing muscular fatigue on long rides. Monitoring cadence helps you develop a more efficient pedalling style and avoid grinding low gears, which accelerates fatigue and increases injury risk.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eHow do I install it?\u003c\/strong\u003e\u003cbr\u003eThe sensor attaches to the crank arm of your bike — no tools required.
