P Zero Velo 4S Over a century of racing know-how is finally available to those who ride to race themselves. With P Zero Velo, your cycling performance now meets the reliability, the road handling and the grip Pirelli is famous for. Because a tyre’s performance is also yours
Discover the result of more than two years of Pirelli development, available in three different clincher tyre models
Harsh weather? Cold temperatures? The 4S is the way to go. With outstanding wet grip and puncture protection, this clincher delivers a high-performing ride. Its unique tread design is developed to shed water from your path, allowing you to enjoy formidable control, even in challenging weather conditions. Wet or dry, the 4S will rise to the challenge.
Pirelli's SmartNET Silica grants both rolling efficiency and wet grip, delivering an all-season tyre with outstanding performance
Tread design developed with FGD and ICS technologies provides great handling and water drainage, even in harsh weather conditions
Overall increased SmartNET Silica tread pattern thickness in addition to an aramid fiber puncture-resistant belt ensure extensive mileage and reliability in bad weather and cold temperatures

LAYERS TREAD The rubber belt, the design of its pattern and the cross section all are at the heart of the performances of a tyre: the contact point between the ground and the bicycle. It is made of a mix of carefully selected and balanced chemical elements and engineered grooves, that greatly contribute to the tyre's outstanding performance. Made from our innovative SmartNET Silica and ICS and FGD technologies, it provides all-round cycling excellence.
RUBBER COMPOUND Derived from our vast motorsport experience, on both 4 wheels and 2 wheels, whether on- or off-road, Pirelli’s SmartNET Silica is an important innovation in bicycle tyre compound technology: thanks to its nano-rod conformation and the resulting network generation, coupled with the natural chemical water affinity of the Silica itself, it solves the traditional trade-off of rubber compounds, ranking high on opposite features such as rolling and wet grip, mileage and puncture protection.
CONSTRUCTION Developed over a 127tpi casing, our tread features Pirelli Functional Design Groove and Ideal Contour Shaping technologies: the casing textile is designed to match contour for optimal footprint, while a different crown and sidewall radius guarantee controlled and specific tire deformation at different speeds and lean angles. On top of this, our lightning bolt groove design, derived from our experience in motorbike racing tire design, adds optimal water drainage at different angles and force loads, while ensuring low noise output and quick warm up times, for immediate maximum grip levels, period.
BREAKER An aramid fiber belt located underneath the tread in order to protect the casing from sharp objects: aramid is a fiber with high cut and abrasion resistance. Its light weight and flexibility also ensure rolling efficiency and overall performance of the tyre.
