According to today’s experience, I can only advise against buying cheap air hoses from the hardware store. Although they are somewhat flexible and usable in summer, they used the part today at 2°C to lower the wheels with the air screw. The hose was just as stiff as a garden hose in which water is frozen. Almost not to be used. The usable length was just half instead of 10m, because the bends were not to be pulled straight. So rather an F I’m not buying for 20€.
