TIP:
Garmin recommends you secure your
bike on a stand while installing the sensor.
1
Place and hold the speed sensor on
top of the wheel hub.
2
Pull the strap around the wheel
hub, and attach it to the hook on
the sensor.
The sensor may be tilted when
installed on an asymmetrical hub. This
does not affect operation.
3
Rotate the wheel to check for
clearance.
The sensor should not contact other
parts of your bike.
NOTE:
The LED flashes green for five
seconds to indicate activity after two
revolutions.
