I bought these tires for a cyclocross bike, but I don't race cyclocross. I bought the bike to use as a winter bike and for the occasional foray onto gravel roads. The bike came with 35mm Schwalbe Sammy Slick file tread tires and they suited my style of riding, but they did wear quickly. When it came time to replace the OEM tires, I decided to stick with a file tread design in a 35mm width (I'm a big guy at 6'5 and 215lbs, so I need the extra width versus a standard 33mm cyclocross tire). I've had good luck with Conti tires, so my decision to purchase these tires was made pretty easily.
Out of the box, these tires are good looking. The file tread is deep, but the knobs are not very aggressive. They mount easily and inflate to a nice round cross section. On the road they ride quietly and comfortably. They're not as plush as, say, Conti GP 4000's, but that's down to the carcass. These tires are built up on fairly course fabric. Good for durability, bad for ride quality. But they're meant to be used off road and, when used off road, they're fine. I've got some miles on them on grass, dirt and gravel and they've been fine. No lack of traction despite the small shoulder knobs and no flats. If they last longer than the Sammy Slicks, I'll be happy.
So ... In summary ... These seem to be good gravel tires. There are better road tires and there are better cyclocross tires but, if you spend a fair amount of time on dry grass, gravel and or dirt, these tires will be fine for you.
Thank you for your feedback.
