Meet the newest addition to the ever-expanding Pirelli bicycle tire line-up, the Cinturato Velo. The tire making giant’s first tubeless ready offering, the Cinturato Velo is designed to deliver enhanced puncture protection in any condition and on any road surface thanks to the two rubber coated fabric plies that form a belt around the carcass.
Indeed, it is a multi-purpose tire intended for varied uses, from on-road racing, to training sessions, to riding on gravel roads and paths. During the design process, Pirelli engineers conducted extensive studies on the development of the most appropriate bead shapes, conducting dynamic tests on clincher tires with and without inner tube, so as to verify tire performance and road holding in both configurations.
Along with the launch of Cinturato Velo, Pirelli has also introduced Armour Tech, a new technology developed for cycling applications where the carcass is reinforced with a layer of nylon and one of aramid.
The Cinturato Velo also uses Pirelli’s patented SmartNet Silica compound, which has been further strengthened by the use of aramid fibers in varying concentrations. Known for their high tensile strength and low weight, these fibers ensure excellent cut-through and impact resistance. (No wonder they are also used in bulletproof vests.)
The fibers get thicker from the outermost layer of the tread to the layers underneath. The first layer of the compound ensures the tire’s grip performance, rolling resistance, and mileage, but does not hold on to pebbles or granules, which, as the wheel turns, may penetrate through the carcass and cause punctures. The next layer is enriched with a greater quantity of aramid fibers to improve its structural characteristics and at the same time ensure durability and puncture resistance.
It is these combined efforts that ensure the features of the tire in terms of puncture resistance, as well as the uniqueness of the patent requested by Pirelli. When a sharp object tries to perforate the compound layers, the density of aramid fibers around the entry point increases, making for enhanced resistance to penetration. As a result, the foreign body cannot go through the inner puncture protection layers.
The Pirelli Cinturato Velo comes in a wide range of widths to meet the needs of a wide range of end users and market segments. To learn more visit velo.pirelli.com.
