Had my first ever pinch flat last Friday, 21 mph on a flat road. Using 25mm Gatorskins pumped to 110 psi, rear tire. I went back to see what I ran over. There was a solid steel wedge, apx. 1" x 1" x 3/4" thick. The tube blew out with two holes opposite of each other.
I weigh 175 lbs, didn't think I was to heavy for the volume or that the psi was to high. In my case, I think the hard steel edge was the cause.
