Vittoria Zaffiro 700x23c Clincher Road Tires (review)

I started using my second pair of Vittoria Zaffiro 700x23c clincher road tires, so I decided to write a review. I use Vittoria Zaffiro’s as a training tire (usually in winter). They are not suitable to use in the races, since they are a bit heavy (340 grams) and have a bad rolling resistance.
