The P ZERO™ Race TLR RS represents the latest addition to Pirelli's range of P ZERO™ Race tyres that are made in Italy. It has been developed in collaboration with professional athletes from Pirelli's World Tour teams to deliver superior speed and grip performance compared to any other tyre in the Pirelli range. This achievement is made possible by the new SmartEVO² compound, formulated with the know-how and latest materials used in Motorsport, ensuring further improvement in grip and handling on both dry and wet surfaces. Additionally, Pirelli have lightened the patented SpeedCORE™ structure, featuring a thin, hermetic layer of rubber compound enriched with aramid particles. The combination of these factors has made it possible to create a high-performance tyre that is even faster for competitors, but also for those who wish to benefit from the same tech as the pros SmartEVO² Compound The new SmartEVO² represents the latest advancement in our high-performance racing bicycle tyre compound, enhanced by incorporating Motorsport expertise at the highest level and the needs of modern World Tour racing. It evolves from the SmartEVO blend of three polymers with 'smart' characteristics, utilizing new materials and innovative mixing processes, now possible at Pirelli's manufacturing plant in Italy located just close by Pirelli's R&D global headquarter. This results in improved overall grip, especially on wet surfaces, and a reduced rolling resistance to record level for its category, elevating both performances and handling feelings to what the fastest World Tour racers in the world demand SpeedCORE™ Structure SpeedCORE™ is an innovative tubeless-ready construction developed by Pirelli (Patent Pending) for there high-performance cycling tyres, representing the most advanced TLR technology to date. Derived from Pirelli automotive know-how and made possible by newest production plant in Italy, nearby Pirelli's Headquarter in Milan, SpeedCORE™ construction consists of a thin air-tight layer of rubber compound infused of aramid particles. This layer covers the internal part of the tyre and thanks to the presence of the aramid into the rubber blend, it allows for better mechanical resistance, improved air retention and overall greater flexibility: all contributing to the tyre's overall performance Specification Made in Italy.
