You set out on the long-awaited Sunday ride with your MTB, racing, or trekking bike, only to realize that the tire pressure and the pressure of the mini pump you brought along are too low. Pumping the tires at the nearby gas station with the usual pump for car tires? Good idea, if only your bike didn’t have a Dunlop or Sclaverand valve. This dilemma is solved by our flexible, intelligent everyday helper in a sleek design: Compatible with all common valves, the valve adapter screws onto the Dunlop or Sclaverand valve and, thanks to its car valve connection, provides access to the powerful gas station pump. The aluminum mini-tool, designed as a practical keychain, also features an integrated valve key that allows you to loosen and tighten AV and SV valve inserts.
