The tread is glued by hand on the casing, a labor-intensive process exclusively used for premium tubulars. The tubular tire’s round profile gives it several advantages over any clincher. Cornering is more predictable and shock absorption is superior. Also, the broad glued interface to the rim spreads shock loads more evenly through the casing, letting the tire absorb big hits without deflecting or slowing down. Vittoria strongly recommends Mastik Pro, offering great adhesion even at high temperatures (up to 140 degrees Celsius).
VITTORIA OPEN TUBULAR
The open tubular has exactly the same production process and properties as the tubular, except for the sown-in inner tube. Open tubulars are handmade with aramid folding bead for optimal clinching.
VITTORIA OPEN TUBULAR, TUBELESS READY
The open tubular TLR shares the same production process and properties as the open tubular, with the addition of a stronger bead material and a chafer for sidewall protection. For optimal safety, this construction is designed to withstand 18 bar of pressure on a standard alloy tubeless rim.
