Pirelli P Zero Velo 4S Road Tire

When the temperatures drop, roads are rougher, or the weather makes your training ride an adventure you need tires that can still perform, delivering grip and control while maintaining flexibility, the PZero Velo 4S Road Tire becomes your best friend. The 4S has all of the characteristics and technologies of the standard PZero Velo, but adds even greater puncture protection and wet grip to tackle adverse conditions. What do you sacrifice? How about 15 grams in the 700x25 versus the PZero Velo's all-around greatness. A surprise from a late entry into today's bike tire market? This is Pirelli, a company with years of premium tire development and construction at the highest levels of motorsports. Still, we are talking about bike tires, which operate at slower speeds, higher pressure, and have very different overall requirements. In search of excellence and innovation, Pirelli's design and engineering team turned to expert cyclists, riding thousands of miles across different countries and in varying weather conditions, to ensure that the Pirelli bike tires meet their own standards and every cyclist's expectations.

The rubber and tread system of any tire creates and ensures performance. By engineering the tread and rubber systems together, Pirelli has been able to deliver the PZero as a lightweight, race-level clincher than be trained on daily. Three innovative technologies are incorporated to achieve this: SmartNET Silica, Functional Groove Design (FGD), and Internal Contour Shaping (ICS). The silica compound delivers reliable grip in both dry and wet conditions, and delivers high rolling efficiency, thanks to its natural anisotropic orientation, which reduces heating while increasing elasticity. FGD is designed for extraordinary cycling comfort and water drainage. The narrow angle at the center of the tire footprint ensures wear regularity, while the wider lateral angle provides confidence and responsiveness at bend apex. The inverted lightning bolt shoulder-wall pattern design effectively reduces noise and helps to drain water, for a smooth cycling experience. Here you see a mjor difference in the PZero Velo 4S versus the standard PZero. The 4S uses a lightning bolt shape but instead of a single inversion, it features 4, which seriously enhances the water dispersal and cornering grip. The FGD progressive groove depth allows cyclists to enjoy high mileage and swift handling reaction. ICS utilizes different crown/sidewall radius and textile designed to match optimal footprint contour; which delivers stability/control with sensational handling feedback with an ideal tire shape.

All this innovation is integrated with some fairly standard, yet incredibly effective existing cycling tire technology. A 127 tpi casing is supple and reactive, and it is protected not only by the rubber compound, but also by a lightweight and flexible aramid fiber belt that can stop punctures, but also is abrasion resistant. This combination of proven technology, engineering innovation, material science and years of high-level tire development come together to lead Pirelli into the highly select, top tier of bicycle tire manufacturers.
