Let me start off by saying that these tires are NOT for everybody. They are expensive, and they will not last as long as most other tires.
With that said, Vitorria is still my go-to tire. Life is too short to ride cheap tires. Wouldn't you rather ride great tires that need to be replaced more often, than okay tires that last forever? The Vittorias are the most comfortable, grippiest, and smoothest-rolling tires I have ever experienced.
This time of year, I opt for the Corsa CG, better known as the Pave tire. They are just a bit wider than Vittoria's normal road tires. This gives a little extra cushion to smooth out the ride when road conditions are not ideal. They are so smooth, you may think your tires need more air. They don't! This is what it feels like to ride high end tires. Smooth, but incredibly low rolling resistance.
Stomp on the pedals, and the instant acceleration should put any fears to rest.It's no coincidence that the Pave is the professional's tire of choice for the early Spring Classics, where conditions are never ideal and the cobbles put tires to their ultimate test. On cold slick roads, the Paves offer levels of grip that compete with most tires in dry conditions.
Don't let the 700 x 24 dimension fool you into thinking that these are recreational use tires. They are not. These are performance tires that I would never hesitate to race on. They accelerate as well as any, they corner better than most, and they ride smoother than all but the best tubular tires. It really does feel like you are riding a tubular, but with the convenience of a clincher.
For the ultimate racing tire, though, check out the Vittoria Corsa CX. They come in a standard 700 x 23 dimension, as well as a 700 x 21, but sacrifice a little bit of the Pave's puncture resistance for ultimate performance. Review coming soon!
