The Coros FD03 Bike Cadence Sensor helps you ride more efficiently by tracking your revolutions per minute (RPM). Optimizing cadence allows cyclists to maintain endurance and power across varied terrain and training sessions.

Perfect Your Pedal Stroke: Knowing your cadence helps you develop a smoother, more consistent pedal rhythm. Whether you're riding outdoors or on a spin bike, the sensor helps you dial in your ideal cadence range to boost both performance and comfort.

Universal Bluetooth Compatibility: Easily pairs via Bluetooth with most bike computers, smartwatches, smartphones and training apps. Unlike many sensors, it’s also compatible with most indoor spin bikes—giving you seamless feedback across your rides.

Quick, Discreet Installation: The compact unit securely attaches to your bike’s crank arm and stays out of the way while you pedal. Its streamlined profile ensures no interference with your ride setup or motion.

Battery That Goes the Distance: Powered by a CR2032 coin battery, the FD03 offers up to 12 months of continuous use. Installation and replacement are easy, letting you focus on training instead of charging.

Made for Every Ride, Rain or Shine: Its IP67 water resistance rating protects the sensor from dust, sweat and splashes, making it rugged enough for any training environment—indoor or out.

Weighing just 11g, the Coros FD03 is a featherlight essential for serious cyclists. Not compatible with ANT+ devices.
