Monitor your pedaling cadence and / or speed with these easy-to-install, self-calibrating wireless sensors
Simply connect your sensors and go. With no magnets or ALTRA exposed parts for alignment, these sensors are easy to install, store and move from bike to bike.
Cadence sensor attaches to any size crank arm. Measure your pedaling cadence to get the most out of your workout.
The speed sensor connects to both the front and rear hubs of your wheels and automatically calibrates with your compatible Edge® or Forerunner® to give you accurate speed and distance data, even indoors on a turbo trainer.
Combine both and improve your personal best.
