I just got a set of Espoir Sport tires from a customer who rode them for a week on his new Roubaix and replaced them with the Roubaix tires. I have one hundred miles on them and will testify that they pretty much suck eggs. They are slow and don't accelerate well either. My guess it that they will wear relatively quickly, too.
The tires I normally ride are the cheapo Continental Ultra Sport. They are no match for the GP 4000 or 5000 by any means, but they are better than these Espoir Sports, plus the Contis wear very well.
