{"product_id":"wahoo-rpm-cadence-sensor","title":"Wahoo RPM Cadence Sensor","description":"\u003cp\u003eA small magnet-less sensor that straps to your crank arm and reports cadence. 7 grams, a CR2032 that lasts up to twelve months, and nothing to align or maintain.\u003c\/p\u003e\n\u003cp\u003eFor indoor riders this is the sensor that actually matters. If you train on a spin bike, on rollers, or on a wheel-on trainer that reports speed but not cadence, your training app has no idea how fast you are pedalling — and cadence is half of how power gets made. Adding this fills the gap for the price of a couple of coffees.\u003c\/p\u003e\n\u003cp\u003eUnlike a speed sensor, it works on anything with a crank arm, including spin bikes and gym bikes. It measures rotation rather than wheel movement, so no wheel is required.\u003c\/p\u003e\n\u003ch2\u003eWho this suits\u003c\/h2\u003e\n\u003cp\u003eAnyone on a spin bike, gym bike, rollers, or an older trainer without cadence reporting.
