Cinturatoâ„¢ RC Classic 700C x 40 Gravel Tyre.Size:700C / 40.Cinturato Gravel RC is the gravel-racing specific tyre, derived from our experience in the biggest competitions around the World and the feedbacks of our PRO athletes.The tread design is inspired by the Scorpion XC RC, focussed on two key Features:higher average speed on straight and fast lines, improved lateral grip when off-road cornering Features:- Racing.- Speed.- Puncture Resistance Technology:Speedgrip Compound:- The Speedgrip Compound is a gravel-specific rubber formulation born from the Pirelli experience in the World Rally Championship where the performances of speed and grip on and off-road are crucial.This chemical formulation rely on the polymer matrix of the MTB-specific SmartGRIP Compound while lowering its rolling resistance.The gravel application requires good speed and on-off road capabilities, for this reason our engineers tweaked the compound features towards a better energetic efficiency with a little compromise on the grip, the result is a predictable compound with solid performances on and off road.Techwall Gravel:- Our engineers wisely combined the technologies derived from road- specific reinforced casings with the MTB-specific casings to obtain our most advanced gravel casing whose performances are obtained with the use of special fabric reinforcements and thicker layers of rubber in specific areas of the tyre.On the road the majority of punctures are caused by the penetration of sharp objects while off-road the most common punctures are caused by sidewall cuts, for this reason the TechWALL Gravel features a cut-resistant 120tpi fabric all over the perimeter of the tyre still offering a supple riding feeling.
