You probably don't think about the tubes you put inside your tires, but with Vittoria's Latex Road Tubes, you'll have a slight advantage when it comes to speed. In testing, latex tubes are smooth enough to reduce rolling resistance by a few watts. And while a few watts may not seem like much, when you add in that nearly 75 grams of weight are shed by switching to the Latex tubes, the seemingly innocuous tube starts to make a dent in your results. The lighter tubes mean quicker acceleration. In addition to being faster, latex tubes are also more elastic to increase puncture resistance.
