Seeing as the Corsa N. EXT G2. 0 Tubeless Tire is deemed worthy of professionals that race at the highest level, we're happy to spec it on our road bike when looking for peak performance. Vittoria uses their TLR Tubeless design on this tire which lets us run lower pressures for enhanced traction, and the 320TPI Corespun-K casing provides reliable durability to ensure we make it through race day.
