Every time I go on a ride, I get a flat on my rear tire. I start off on the ride and about a half hour into it, I get the flat. It's like clockwork. I either patch it or throw on a new tube, and then head back home. This has happened on my last 5 or 6 rides. I've checked the rim, checked the valve (the puncture's never near the valve), checked the tire...I can't figure it out. Any suggestions?
I asked a third grader and he said, "Maybe he's riding the same route and there are thorns or glass in the same place each time?"
