Benefiting from the different properties of each compound, including the G+ Isotech*, their distribution is extensively tested to deliver the best products imaginable.
"The Vittoria Corsa Speed Open TLR truly is the fastest road bike tire in the world. If you have tubeless-ready wheels and want the fastest tires, look no further and get a set of these. If you don't have tubeless-ready wheels, get a set of these and a set of tubeless-ready wheels. Rating: 5/5. Test verdict: Highly recommended." - Bicycle Rolling Resistance
