First bike ever with presta valves, and yes I still hate them, lol. I screwed the adapters on, pushed the
air chuck onto them and nothing? No air would pass through the valves at all. Do you have to do anything special like "unlock" them first or something? Or are these frozen and I need new tubes?,,,,BD
Yes I still hate them, I really don't see how they're superior aside from being narrow for skinnier rims.
