Replaceable Valve Inserts

I've been looking for tubes with replaceable Presta valves but the only one I've been able to find is Schwalbe. Anyone aware of other manufactures with this feature.

The Michelin A1/B1 Aircomp tubes have replaceable valves.

All Continental tubes and tubular tires have replaceable valve cores.

I have a set of AC 350 MTB wheels and with a 40mm tube stem it is a hard go to get the pump on the valve stem without removing the lock nut. Not many mtb tubes with a 60mm stem.

Vittoria make valve extenders that are perfect for my problem. You remove the complete valve assembly from the valve stem (they have flats for a wrench) and insert the extender into the valve stem. The valve assembly is then screwed into the extender and voila, I now have 80mm valve stems that can be opened or closed friom the top.

replaceable Presta valve, seconded that.

I was also looking for replaceable Presta valve that is a little longer then the ones used in Asia bikes. The Presta valve that is on most tube mountain bikes tend to break off at the base. I have had it happened 4 times on the road. I usually have a flat then walk the bike then when I get to replace it I found that the base has been riped; off course due to dragging on the dirt. I replace the valve with the local made one but they are a little short for the double wall rims. I wonder if anyone know where I can get some in the states? The regular ones, I can't replace it once it fall off.

I think Topeak also makes a valve extender that doesn't require removal of the valve core.

Continental also makes those. They work well.
