http://www.sportsauthority.com/large...p8044531dt.jpg I just put 2000 miles on a set of these over inflating them 20 percent to 78 psi without any failures. They have a kevlar belt and fold like kevlar tires but are really steel beads. You can get them at walmart kmart target and others for around $16. I'm testing the crusier tread pattern now. These tires are as good as the trek invert 2k which is no longer made.
