Monitor your ride with these wireless, easy-to-install speed and cadence sensors. With no magnets or other exposed parts for alignment, these sensors are easy to install, store, and move from bike to bike.
The second generation Speed Sensor attaches to the hub of one of your wheels and automatically calibrates via the Edge ® cycle computer or compatible Garmin device to give you accurate speed and distance data at all times. The sensor stores the data of your rides even without an edge or compatible device; once connected the data will be shared between the two devices
The Cadence Sensor attaches to cranks of any size and measures pedal strokes per minute.
