Excellent tire for road and gravel. Not super flat resistant but good. Not a good tire for extensive mud, grass, sand, or roads where there are a lot if thorns or glass. Wonderful ride, reminds me of riding tubulars way back when... I have been riding them on at least one bike for more than 7 years... On most gravel roads low pressure is much more important than tread for traction so slicks do work well.
