With our road racing tyres, Vittoria reaches for the skies: for the finest, fastest-rolling, most flexible, best-handling performers on the planet. But as every racer knows, to finish first, first you must finish. That’s why, in parallel with our exclusive casings and tread compounds, we develop the industry’s most advanced flat-protection technologies. Our aim is to protect the tyres against flats caused by shocks or road débris, while preserving the legendary Vittoria ‘feel’ that riders so value. This is not trivial. Every added layer, of rubber or fabric, tends to stiffen the casing and degrade its flexibility. Thanks to constant research, we have minimised these effects. |

Puncture Resistant Belting (PRB) is a technology utilized on most Vittoria tyres and tubulars. Our original PRB® consists of a thin, lightweight layer of high-density nylon placed under the tread, where it prevents perforation by flints and other road débris. |

PRB® 2.0 develops this technique, using a new higher-density aramidic fibre that’s up to 40% more resistant to cuts, yet lighter and more flexible. PRB 2.0 has proved an outstanding flat-protection system, virtually eliminating punctures among the teams who used Vittoria tubulars in the 2009 Tour de France and 2010 Parix-Roubaix. |

Mithril is a lightweight, tear-resistant polymer weave that’s applied to the tyre sidewall. We use it on tyres, such as those designated Tech, that are intended for use in tough conditions where there is a risk of damage from street or trail débris. Mithril is strong but also flexible. The stronger sidewalls confer greater cornering stability but don’t degrade the renowned Vittoria ride comfort and bump absorption. |
