Tufo tires are the equal of other brands when it comes to their lightness and rolling resistance. But where they stand alone is in their tubular/clincher technology. Unlike any other brand, you can mount Tufo tubular/clincher tires without a separate clincher inner tube. Rather, they're part of the tubular/clincher tire. It offers the sweet ride of a tubular with none of the mess. And Tufo sealant and Tufo valve extenders make living with high-end tires that much easier.
