Valve extension for high profile rims and boogie wheels.
The Schwalbe is suitable for all Sclaverand valves with replaceable valve inserts. The advantage of the Schwalbe valve extension is that you are not dependent on tubes with a long valve stem on your tour. So you can pimp a standard tube from your specialist or in the store. The valve extension has a reliable seal on the thread, so there is no risk of self-venting.
