P ZERO™ Race SL‑R is the fastest tyre in the P ZERO™ Race range.

Engineered to maximize aerodynamics through the PAAS (Pirelli Advanced Aerodynamic System), reducing drag and enhancing the sailing effect. The new LiteCore casing, Pirelli’s lightest and most efficient TLR construction, delivers maximum smoothness and an exceptionally supple ride. The SmartEVO² compound ensures outstanding grip and control in both dry and wet conditions. Fully slick, with micro‑texture and integrated aero details, it is Made in Italy for top performance on the road and in time trials.

Technology

Compound
The new SmartEVO² represents the latest advancement in Pirelli's 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 own manufacturing plant in Italy located just close by the 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.

LiteCORE
LiteCore is Pirelli's fastest TLR casing: engineered to provide maximum rolling efficiency at low weight, while offering high suppleness to enhance comfort, grip, and road feel. A Tubeless Ready construction developed to ensure low rolling resistance and a superior riding sensation.

Structure
PAAS is Pirelli’s advanced aerodynamic technology, developed through CFD analysis and wind‑tunnel testing to increase the efficiency of the tyre+wheel system. Its patent‑pending profile creates a seamless transition between tyre and rim, keeping airflow attached longer, reducing flow separation, and maximizing the sailing effect for lower drag. Designed for modern wide rims, PAAS delivers stable airflow, measurable aerodynamic gains, and consistent performance over time, even as the tyre wears. The result is a faster, more efficient and more stable system with an ideal balance of aerodynamics, grip, comfort and rolling resistance.
