The new size 700 x 29 is optimized for a perfect fit and accurate cross - section width on 25 mm internal width hooked or hookless rims thereby maximizing the aerodynamic advantage on a 25 mm inner width rim. Accelerate to victory with the new Vittoria Corsa PRO Speed tyre for Time Trials and Triathlons The Corsa PRO Speed tyre is the result of extensive research and development conducted by Vittoria's team of experts through three seasons of racing analysis. With a strong commitment to provide racers with the best possible products Vittoria has designed a tyre that maximizes speed grip and control in time trial and triathlon use. Featuring an advanced Graphene + Silica compound specifically designed to provide unparalleled efficiency while returning a very high level of grip on both dry and wet surfaces Corsa Pro Speed ensures faster times and a smoother ride. Vittoria collaborated with countless athletes and team to achieve this milestone. Jonas Vingegaard’s domination of the Stage 16 Time Trial at 2023 Tour de France highlighted a proven trend supported by Wout van Aert’s Belgian National Time Trial victory as well as Jos van Emden’s Dutch National Time Trial win all using the Corsa Pro Speed. The fastest tyre made faster by seamlessly tapering the tread into the sidewall the Corsa Pro Speed construction combines the Graphene + Silica compound ultra-supple cotton casing and updated tread pattern all electrically cured to minimize rolling resistance. The results of internal testing show an improvement in rolling performance of 5% with 2% savings in weight. The circumferential grooves distribution on the tread has been optimized compared to Corsa Speed with a wider center slick area and closer grooves which provide suppleness and cornering edges. Corsa PRO Speed Corespun 320 TPI cotton casing is extremely lightweight and guarantees ultimate suppleness speed and enhanced cornering grip. Graphene + Silica compound ensures speed and confidence through a range of surface conditions for the ultimate control. The graphene + silica technology is the same as in the Corsa Pro and Corsa Pro Control but the formulation is specifically designed for the intended TT use therefore maximizing speed yet providing a very high level of grip on wet as proven during 2023 race season. Extremely lightweight tyre that guarantees ultimate suppleness and speed without sacrificing the grip. Tread thickness is lower than Corsa Pro and comparable to previous Corsa Speed in the center but smoothly tapering toward the sidewall in its seamless construction allowed by the new manufacturing process which includes electrical curing TSS HOOKLESS compatible for Tubeless-Ready TLR 28mm width size up Features: Material: Corespun 320 TPI Compound: Graphene and Silica Discipline: ROAD COMPETITION RACE Construction: Tubeless Colour: Tan Size : 700-29c ETRTO: 29-622 Weight: 255g
