I just put these on my Giant Escape and they ROCK:

Using 28's, but 25's would be insanely fast. They have the same tread
design as Conti Grand Prixes.
I'm getting a second set for my Specialized Sirrus Comp.
You might look at the Escape. I prefer the geometry on it
over the Sirrus, although the Sirrus is an excellent bike.
Shop around. You can get the SS+ for a great deal on sale.
