Take this with a grain of salt, since we are the makers of these tires... but we only sell what we use, and we use our bikes hard. We've ridden these tires (and the similar Grand Bois Extra Légers) on gravel for many hundreds of miles, and they work very well. I put them on my son's bike, and he also hasn't had problems on some pretty rough terrain. Check out

The one place they don't do well is highway shoulders with all the steel wires that accumulate there...
