Kind of an odd topic here.

I generally use Conti tubes, but the folded tube plus box takes up what seems like a significant amount of space compared to other tubes (specialized) I've seen a some local shops. I'm trying to cut down on what I carry, so I'm looking for the smallest (or close to it) folded tube around. Don't particularly care about weight, just volume. And it doesn't need to be any every day tube...just enough to carry me ~30 miles if I flat far away from home.

Any thoughts?
