I posted my last update from a picnic table in Hanksville UT where I was sitting with three other bikers who were headed east. I had already done fifty miles to get there and was planning on taking a break in the shade anyways so it worked out nicely. I know I made a post about how I hadn't had any flats yet, an it seems like I jinxed myself.
After taking care of everything in town I left, planning on spending several hours in the shade of a bridge by a river. I managed to get down to he water ok, and spent several hours relaxing in the shade. I realized that I had pushed my bike through some prickers to get there, since I was pulling them off of my socks, but didn't really think much of it. After I was done with my break I pushed my bike back u to the road, where I realized that both my tires were flat. Since I had been with my bike the entire time I knew it was punctures and not just someone letting the air out.
Replacing both tubes was interesting, since I was sitting on the side of the road with my bike completely in pieces. I started fixing one flat with a patch kit, when I decided to just use the two new inner tubes I had bought, and I would fix he flats later in camp. When I was part way through that I realized that the valves on the new tubes were different, being presta instead of schrader. I wasn't sure if my pump would work with these, but I knew some pumps were interchangeable. It took some work on the pump, and I had to take apart the pump head an reconfigure it, but eventually I got the two new tubes on, got the tires on the bike, and got them both inflated with air. Now I'm just hoping that the sharp points I felt on the inside of the tires were the only ones, and that I was able to fully remove the sharp bits. Otherwise I'll end up with more flats tomorrow morning.
