i have put 2000 miles on my Endurace cf8 since July 22nd. I am old and fat and man do I really like putting miles on this thing. I live where the roads are pretty crappy and i actually just put on a new set of tires only because the rear squared off so bad, they come with 30mm up front and 32mm on the back and i decided to try 30mm all the way around. I put 60 miles on them yesterday and was pleased enough that if the weather permits going to take them out for a 100 miler tomorrow. for the money not sure you can do any better.
