Picture race day...what are you going to be rolling on? A tubular tire that is tough and light--like 250 grams light. The Vittoria Corsa CX III X-factor tubular race tire has an incredible 320 TPI casing, so supple that even at max pressure, a nice and efficient swath of tread hugs the road without absorbing any of your energy. And don't worry about flat resistance, the corespun cotton casing twists staple cotton fibers around a central filament core, creating one yarn from multiple fibers for 40-50% more strength than typically spun materials. Corner and break away like a pro on some tires that point you directly for the podium.
Ultra high 320 tpi means excellent road hugging and excellent efficiency
Great flat resistance--dependable for race day
This is a race tire, so some overall wear life is sacrificed in the name of ultra light weight
