Does not work with Vittoria Air Liners-Otherwise are fine
The Valve Stems work fine unless you have Vittoria Air Liners. This is due to that fact that they only have a single port at the bottom of the valve. Ports on the sides of the bottom of the valve are needed otherwise the liners block the flow of air into the tire.
