Product Information
The Cadence Sensor 2 straps to the crank arm and measures pedaling cadence. Like the speed sensor it uses no magnets and needs no alignment, so fitting it is a matter of choosing the right strap and pulling it tight.
Cadence is the number that most often explains a rider's fatigue pattern — spinning too low a cadence loads the legs, too high loads the cardiovascular system — and it is not something a GPS computer can infer on its own.
It pairs with Edge computers, compatible Garmin watches and training apps, and moves between bikes as quickly as it goes on.
