Hello After I made a few tests at home it is today came the first use! On my current tour came towards me a push stroke racing colleague. He said he gets no air in the tires because the valve is too short! He was surprised when I took out my little pump but when he saw that I first turned the short hose to the valve and then the pump on the hose as it was enthusiastic. Then pumped and ready !!! A great part of what easily fits in jersey pocket or the can be attached to the frame with supplied bracket. Gruss Thomas
