Pirelli has launched its new P ZERO Race TLR, a tubeless version of its clincher tyre for road bikes. This product has been manufactured in the modernised Pirelli plant in Milan-Bollate, Italy.
The new tubeless-ready tyre by Pirelli is positioned as being the fastest of the brand’s road bike range, and features a technology called SPEEDCORE.
The structure of the P ZERO Race TLR features a tyre tread made with a SmartEVO formulation. This is a compound of polymers created to offer grip and low rolling resistance. The tyre is different in the inside compared to its predecessor.
The use of the new SPEEDCORE technology claims to offers low rolling resistance and protection from punctures, thus reinforcing the casing – without making it stiff – through the use of aramid fibres.
Pirelli adds that aramid has chemical-physical features that allow for high resistance to traction, cuts and heat, thus favouring the mechanical properties of the tyre itself.
This new technology has been developed thanks to Pirelli’s experience in the field of compounds for racing tyres and has allowed for the reduction of rolling resistance, thus improving the smoothness of this tyre by 24% compared to the P ZERO Race TLR’s predecessor (according to Pirelli in-house testing carried out with tyres in the size 28-622).
The aramid fibres bind with the other chemical elements in the rubber, and the structure of the new P ZERO Race TLR is said to be much more flexible and thinner than a traditional butyl rubber layer, with improved mechanical resistance characteristics compared to the previous version of the product and with a better level of puncture protection than a classic bead-to-bead fabric casing.
‘Compared to the previous version on the market, the weight and excellent grip and reliability characteristics in dry and wet conditions remain unchanged, confirming the product as a reliable and high-performance all-rounder, a benchmark in its category.’
P ZERO Race TLR is already available in sizes 26-622, 28-622, 30-622 (all also in the ‘Classic’ version) as well as size 32-622 with black sidewalls. The sizes 35-622 and 40-622 will enter the market later this year.
