Yes, you can use an alloy extender, but obviously, because of the difference in material hardness, you’ll want to take care not to stress the thread interface (as with overtightening). Like, I might prefer to use a press-on pump head rather than a thread-on one, given the choice. I don’t use extenders on mine, so I have no idea how real the risk is, but as I said, knowing nylon is softer than aluminum…
Do you know you can get Aerothans with 80mm valves? They originally released with 40mm valves only, but there are 80mm now, at least in the Race and Endurance Race models. Using a long stem should be preferable to an extender regardless of stem material.
