The Pirelli P Zero Race SL-R TLR 700 tire featured here at Escapa is the highest-performance road tire in the P Zero Race family, positioned above the P Zero Race TLR RS and standard Race TLR models. It is specifically designed for high-level competition and time trialists, optimizing aerodynamics and rolling resistance.
ThePirelli P Zero Race SL-R TLR 700 tire sits at the top of Pirelli’s P Zero Race family, above the RS and the standard Race models, and is clearly positioned for road racing and time trials. The difference from its younger sibling, the P Zero Race TLR RS, is, according to the manufacturer, a 20% improvement in aerodynamics under normal wind conditions and a 10% reduction in rolling resistance due to tire flex, which translates to a savings of about 2 watts, and, at 275 g for the 28 mm version, a weight reduction of 15 g compared to the RS of the same size.
PAAS (Pirelli Advanced Aerodynamic System)
ThePirelli P Zero Race SL-R TLR tire introduces a profile geometry that Pirelli calls PAAS (Pirelli Advanced Aerodynamic System). The interface between the tire and the rim is a key point where airflow separates from the wheel, generating drag; the PAAS profile (cross-section) is designed to keep that flow attached across the full range of steering angles a cyclist encounters in competition. Pirelli’s wind tunnel data shows savings of 5 to 10 watts at high yaw angles compared to benchmark alternatives.
Key improvements of thePirelli P Zero Race SL-R TLR tire compared to the RS model:
- Aerodynamics: 20% improvement in normal wind conditions thanks to the PAAS (Pirelli Advanced Aerodynamic System), which optimizes the interface between the tire and the rim
- Efficiency: 10% reduction in rolling resistance, equivalent to a savings of approximately 2 watts per set.
- Weight: 15 g reduction per tire (275 g listed for the 28 mm size)
Technical Features
- LiteCore Casing: Replaces the SpeedCORE from the RS model. It is a more flexible and lightweight 120 TPI structure that improves road feel.
- SmartEVO2 Compound: Uses Pirelli’s most advanced chemical formula, designed to deliver maximum grip in both dry and wet conditions.
- Compatibility: Tubeless Ready and compatible with hookless rims, always within ETRTO pressure limits.
- Optimized Profile: Designed to perform best on rims with an internal width of 22–25 mm.
SmartEVO² Compound
The new SmartEVO² represents the latest advancement in our high-performance road bike tire compound, enhanced by incorporating our expertise in top-level motorsports and the demands of modern World Tour cycling. It evolves from the SmartEVO blend of three polymers with “smart” characteristics, utilizing new materials and innovative mixing processes—now made possible at our own manufacturing plant in Italy, located near our global R&D headquarters. This results in an overall improvement in grip—especially on wet surfaces—and a reduction in rolling resistance to record-low levels for its category, elevating both performance and handling to meet the demands of the world’s fastest World Tour riders.
LiteCore Casing
LiteCore is the fastest TLR casing: designed to deliver maximum rolling efficiency with reduced weight, while providing great elasticity to enhance comfort, grip, and road feel. A Tubeless Ready construction developed to ensure low rolling resistance and a superior riding feel.
PAAS Casing
PAAS is Pirelli’s advanced aerodynamic technology, developed through CFD analysis and wind tunnel testing to improve the efficiency of the tire-rim system. Its patented profile creates a seamless transition between the tire and rim, keeps the airflow attached for longer, reduces separation, and maximizes the sail effect to lower aerodynamic drag. Optimized for modern wide rims, PAAS offers a more stable airflow, measurable aerodynamic benefits, and consistent performance even as the tire wears. The result is a faster, more efficient, and more stable system, with an ideal balance between aerodynamics, grip, comfort, and rolling resistance.
