The new rubber, equipped with a special inner tube, guarantees a reduction in overall tyre weight of more than 10%, while maintaining the same grip, smoothness and reliability characteristics. It will be the ace up the sleeve of Pirelli's World Tour teams at the Giro d'Italia:
At the Giro d'Italia 2021, and soon on the market, comes the P ZERO RACE Tub SL.
Pirelli is once again taking on a sacred monster of road cycling: the tubular. A tyre that has seen very little innovation in its history, on which the benefits of one feature have usually been at the expense of others, that are equally important for performance. Very few tyre manufacturers have recently taken an interest in improving the tubular, as this is a niche product, almost exclusively intended for professional cycling.
As with the elite sports in which it is a partner, on two and four wheels, in cycling Pirelli confirms its vocation for continuous product development and absolute performance in the world of racing, without necessarily having a significant commercial outcome. Although the future is tubeless, in all respects, Pirelli recognises that most Pro teams still use tubular tyres. Faithful to its DNA, Pirelli is not stopping the development of this tyre, but rather raising the bar even higher for a product which, in the course of its history, has rarely seen major technical innovations.
DEVELOPED FOR AND WITH PROFESSIONAL CYCLISTS
P ZERO RACE Tub SL is a project that has seen two years of planned, meticulous and constant development. Working on the first tubular, launched in 2018 together with the Mitchelton-SCOTT team (now

LIGHT WEIGHT BUT WITHOUT COMPROMISE
The focal point of this Pirelli innovation is the weight, which is over 10% less than the already competitive P ZERO Velo Tub. A result that translates into just under 100g eliminated from the complete bike and, in particular, from a crucial component such as the wheels. Pirelli's search for a lighter tubular was carried out without penalising the already excellent performance of the tyre: top-notch rolling, high grip even on wet roads, and great resistance to punctures.
At the heart of the P ZERO RACE Tub SL is a special inner tube made of a lightweight, completely airtight material and optimised specifically for use inside the handmade tubular. Instead of the traditional latex, which has been used in almost all Pro tubulars up to now, Pirelli has used TPU, or thermoplastic polyurethane, a cutting-edge material which is being applied to a tubular's inner tube for the first time and which required a great deal of development before it gave the expected results. It offers the same speed performance and puncture protection typical of latex tubes, but with a significant weight reduction and complete airtightness, thus eliminating the chronic pressure loss of traditional tubulars.
The casing of P ZERO RACE Tub SL is made of Corespun with 320 TPI. The latest-generation SmartEVO Compound, which Pirelli has developed for the new P ZERO Race in clincher and tubeless-ready versions, is another feather in the cap of the Tub SL. In the road tests carried out by the teams, the new tyre proved to improve the handling of the bike and the ascent speed, the famous VAM (Average Ascent Speed), offering excellent protection against punctures and greater control at high speeds.
All of Pirelli's World Tour team partners were given the opportunity today to choose this version of tubular ahead of the big Tours. It is likely that riders aiming for the general classification will use them more often than others. Think
