Bicycles need air. Not to breathe, but for suspension. Usually, you rarely need new air, but when you do, inflating can be annoying and a hassle. It would be easier to use an air pressure hose at a gas station—but those air nozzles fit only on car valves. There are two types of common valves: Dunlop valves (also known as “German valves” or DV) and the current international Sclaverand valves (also known as “French valves” or FV). Valve adapters solve this compatibility problem. Our valve adapters are practical, and hang on your keychain, and therefore are always at hand. They are available in different colors of anodized aluminum, and can even be used as a tool for removing and fixing SV and AV valves.
