Garmin Bike Speed Sensor
Having a speed sensor lets you use your Garmin on a trainer and show speed. This new unit senses movement and does not use a magnet. So attaching a spoke magnet is a detail of the past.
The speed sensor straps to the hub tool free and self-calibrates. GPS makes the speed sensor not 100% necessary in most situations, but having a speed sensor guarantees accurate speed and distance at all times even in dense woods or on an indoor track. If you ever ride an indoor trainer, the speed sensor pretty much becomes mandatory.
