• Monitor your pedaling cadence as you ride with this easy-to-install wireless sensor. With no magnets or other exposed parts to line up, this sensor is easy to install, maintain and move between bikes.
  
• The Cadence Sensor 2 fastens to any size crank arm and measures pedal strokes per minute so you can get the most out of your training. ANT ® and BLUETOOTH® Low Energy technology let you send cadence data to Garmin Connect™ and other training apps and compatible fitness equipment for better data when you ride indoors and outdoors. (Water-rated to 1 ATM; ANT ® wireless connectivity does not work underwater.)
