As short as you can find is my suggestion. I have bora 35's with a 20mm valve extender. It's more than long enough.

First, make sure you buy the type that relocates the valve core, not the type that just slides-over an open valve. I prefer the brass-bodied Vittoria ones: ... nders.html

Second, when you relocate the valve core, make sure that you use a few turns of Teflon plumbing tape on the threads of both the valve stem and the valve core. It is much better to make sure that you have a good seal before you glue-up the tire.

With respect to the length, the 30mm version should be the 'right' choice for you.
