Why go latex? The main benefit is clear-cut: Weight savings. You'll save about an ounce per wheel -- 10-20g depending on which tube you compare it to. That might not sound like much, but when you're talking about weight at the outside of your wheel, every little bit really does count. We've also seen tests that indicate latex tubes have lower rolling resistance than butyl rubber. And -- not sure if you should file this in the urban myth department or not -- some folks suggest that latex is more pliable than butyl, giving it superior resistance to pinch-flats.

The only downside to latex is that tube walls are considerable more permeable than butyl rubber. This means that you'll need to air up your tires every single day. No, you cannot skip a day. And if you take a week off riding, your tires will appear flat.
