The tube also includes a removable core Presta valve. This tire includes PPS Ganzo, a lightweight and supple Puncture Protection System placed between the tread and casing to increase resistance to punctures.

The Almanzo is the ideal tire for gravel and adventure riders seeking more control than the Strada Bianca and lower resistance than the Gravel Grinder.
