I have been using High end Vittoria (CX?) tires on the newer racing configuration bikes, but they are darn expensive and I was not getting much mileage on them. I got a deal on a pair of the Continental Attack Force tires, the ones they only sell in pairs with a slightly larger rear than front.
I cursed the rear one royally, as it was the tightest tire to mount I had ever seen, but I am sure singing their praises after a 30 mile ride on them.
I really believe these are the fastest clincher tires I have seen. They feel faster than the Vittorias and every bit as fast as I remember tubulars.
Hope this isn't off topic, but we all have to have tires on the treasures we ride!
