The improved, user friendly speed sensor from Garmin is for anyone who loves convenience. Keep track of your speed during your ride thanks to the easy to install wireless sensor. Attach the Garmin speed sensor and you're good to go. This sensor works without a magnet or other protruding parts, who need to be aligned. Designed to be installed, maintained and transferred easily.
The speed sensor is attached to the hub of a wheel, calibrates itself with your Edge and displays the speed and distance accurately, even when training indoors on the trainer. How convenient do you want to have it?
