The PZERO Race 4S TLR is our first ever year-long racing tyre with a tubeless technology able to provide a high grip in all kinds of weather and an increased puncture protection, still maintaining the racing feeling characteristic of our PZERO Race range. This result has been achieved thanks to the SPEEDCORE tubeless technology, our latest evolution in terms of casing constructions, and the SMARTNET Silica which holds the best formulation for wet and chemical grip among our compounds. As the rest of the PZERO Race range, the PZERO Race 4S TLR is made in Italy in our new Bollate factory.Pirelli SmartNET Silica technology delivers high rolling efficiency, thanks to its natural anisotropic orientation, which reduces heating while increasing elasticity, to help minimise energy dissipation.Enjoy highly reliable wet grip. The wide surface of the silica rod molecules enhances its natural water affinity, delivering confident handling on wet.Puncture resistance and extensive mileage. Pirelli’s SmartNET Silica compound features microscopic rod-shaped particles, that are arranged systematically, rather than chaotically, creating a strong, long-lasting tyre.SpeedCORE is an innovative tubeless-ready construction developed by Pirelli (Patent Pending) for our high-performance cycling tyres, representing our most advanced TLR technology to date. Derived from Pirelli automotive know-how and made possible by our newest production plant in Italy, nearby our 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 performanceSize: 700c x 30mmApprox weight: 365gCasing: 120TPI Speedcore Tubeless Ready
