Bike Sensors

Your Forerunner is compatible with the GSC 10 speed and cadence bike sensor. For a list of third-party ANT+ sensors that are compatible with the Forerunner, go to www.garmin.com/intosports.

Training with a Bike Sensor

Before you start training, you must be in bike sport mode, and you must pair the GSC 10 with your Forerunner.

1Select MODE > Settings > Bike Settings > bike name > ANT+Spd/ Cad.

2Select Yes in the Bike sensors present field.

3If necessary, select More to select the sensor type.

About the GSC 10

Cadence data from the GSC 10 is always recorded. If there is no GSC 10 paired, GPS data is used to calculate the speed and distance.

Cadence is your rate of pedaling or “spinning” measured by the number of revolutions of the crank arm per minute (rpm). There are two sensors on the

GSC 10: one for cadence and one for speed.

For information about cadence alerts, see page 9.

Non-Zero Averaging for Cadence Data

The non-zero data-averaging setting is available if you are training with an optional cadence sensor. The default setting is to include zero values that occur when you are not pedaling.

To turn the non-zero averaging on or off, select MODE > Settings > Bike Settings

>Data Averaging > Cadence.
