Chris Swrote a review of Vittoria Open Corsa EVO CX on March 27, 2015
Familiarity: I've put it through the wringer
I bought these as racing tires. The Open Corsa is arguably the best tire you can buy for rolling resistance, which is what happens when your energy gets soaked into deforming the tire as it contacts the road rather than pushing you forward. For example, to go the same speed with Gatorskins vs the Open Corsas you have to constantly work about 20 watts harder. That's a lot of power wasted. Buying a racing tire is the cheapest way to get faster with no additional effort. Because the tire is soft, the cornering has (so far) been superb. In fact, I've never ridden a tire that could inspire as much confidence as these in a turn. But the very virtues that make them great for racing means that they're going to wear out fast and probably flat more often than a training tire. To minimize the chances of a flat, I run latex tubes. This not only helps even more with rolling resistance and comfort, but latex is better able to tolerate little pokes from whatever slivers I pick up.
When training, I leave a Vittoria on the front--front tires hardly wear at all--and a Continental 4000S II on the back. This lets me have fun cornering while still providing decent rolling resistance and puncture protection where it's usually needed most (in the rear). Even so, the Open Corsa picked up little slivers of rocks while the Conti so far has no marks or cuts. So, again, this is a soft and delicate tire that will reward those seeking speed and handling, like racers--this is NOT for people who value durability.
