Your First Ride
Before you ride with Rally for the first time, you must enter the crank length on your compatible Edge device. You must also enter the crank length when you move the Rally pedals to a bike that has a different crank length.
This procedure contains instructions for the Edge 830 or 1030 devices. If you have another compatible device, see Other Compatible Devices, or go to support.Garmin.com/en-SG.
