Oh and I’m now running Veloflex Black: A great tire! Light, supple and nice rolling.
Just took those off my TT bike to try the Ultraspeeds; they're nice enough, but I've got the 320tpi Open Corsa CX II on my road bike, and they make Veloflex Blacks feel like tractor tyres. Obviously not as big a step as GP4000 -> Veloflex, but as the Vittorias can be had cheaper than the Veloflex they're a no-brainer when it comes time to replace your tyres.
