Descriptions:

• Monitor your pedaling cadence with this easy-to-install wireless sensor. With no magnets or other parts to install, this sensor is incredibly simple to set up and maintain. You can also easily move it from one bike to another.
• The Cadence Sensor 2 attaches to any size crankset and counts pedal revolutions per minute for highly efficient training. ANT+® connectivity and BLUETOOTH® Low Energy technology allow you to share your cadence data with our Garmin Connect online community and other training apps, compatible devices, and fitness equipment for better data when you ride indoors or outdoors (ANT+ connectivity does not work underwater).
