I have the Kenda Kross 27"x 1 3/8" tires and like them enough to be on my third set. I have gotten a lot of use from them easily several thousand miles. They ride well on gravel and are about a mile or two slower than a pasella in 1 1/4" on the road. They hold up well in gravel up to the railroad ballast size rocks on an undeveloped rail trail. On the road I run them 10# over and they can run lower for the sandy cobbles we have in New England. Good tires for the money and they come in tan wall and gum wall versions.
