The Vittoria latex tube is engineered to give riders the performance they need with minimal rolling resistance. Latex tubes have become a rare commodity in recent years causing a shift from latex to rubber. The Vittoria latex tube is engineered to give you the performance and durability without losing peace of mind.
Feel pretty thick for latex. Easy to install. I know they don't have sealant, however, but i heard the puncture but they didn't seem to loose more than 50% and I was able to ride a while before fixing. Make sure you pump up before each ride. As is normal for Latex, they lose air much faster than butyl tube.
