Nightmare ride on perfect morning. Found out that both spare tube valves and the valve of on one installed on the bike are are of the removable core type, so when you try to unscrew your pump's screw on connector, the valves' cores screw out too. The result of this is rapid deflationsville and a long walk. I have never encountered removable core type presta valves before, I didn't even know they existed - until a few hours ago.
