The KYFLIE LUDUS ANTENNA bar is quick and easy to set up. It can be used in all practical conditions. 3-in-1 use: whether the dog is next to the front wheel, without traction or in front of the front wheel, or without traction or with traction, the lanyard will always be kept away from the wheel for the safety of the driver and the dog. Before setting up your case, carefully measure the inside diameter of the tube of your fork in order to determine the choice of the size of the adapters to fix the case. Two adapter sizes are supplied with: 18 mm - 25 mm and 29 mm - 35 mm. Attention, if your practice without a dog is intense in terms of terrain, and your fork goes down on the wheel, then remember to remove the plastic case so as not to damage it! The metal rod of the bar is removable thanks to its simple screwing and unscrewing wheel without tools, allowing the case to be fixed under the fork.
