Put the Vittoria CX on here last week, and they do feel good. At 8 bar (min listed sidewall pressure), the ride feels nicer than the GP 4000s. When first mounted them, also noticed handling feel was more responsive as well. That part surprised me:wasn't expecting any change to the steering feel of the bike.
Sad to report that speed-wise, just haven't felt it yet. Did a couple of "coast-down" trials with my buddy who is on Mich Lithium, and couldn't really see a any difference at all. Forse la velocità del Ferrari è soltanto in Italia?? 🙂
LOL. Forse...
The big difference for me was coming from Specialized Roubaix 25mm... so in all honesty a lot of the 'impression of speed' was there. But they do feel smoother and faster and sexier and lighter and... well, you get the point. 🙂
