The Corsa Evo from Veloflex is a clincher tire with a very soft 320 TPI (Threads Per Inch) Corespun casing and an innovative compound provides exceptional grip and very low rolling resistance. All of their clincher tires, including TLR (TubeLess Ready), are designed with the same artisanal process that they use for their tubulars, handmade in their Italian laboratory since 1981. Handcrafting, tradition, expertise and constant research for clincher tires with extraordinary performance.
