I've got a Vittoria latex tube and a Vittoria valve extender (and a HED one), but they don't fit: I think the threads are a different pitch.
The valve extender instructions show that the entire valve tube is removed and replaced with the extender, which isn't possible with the Vittoria tubes.
What do I need? Different tubes or different extenders?
Different extender. The red Vittoria ones are indeed for the old style of Vittoria tub where the entire valve could be unscrewed. I've always got on well with Conti valve extenders.
Valve extenders and clinchers.
