I was riding on a relatively smooth dirt road when my front wheel got a bad wobble for no apparent reason. I stopped and the tire looked like it wanted to taco but didn't. I was in the middle of nowhere and didn't feel like walking my bike for miles so I removed my front wheel, grasped it by the two "raised" areas and pressed the hub against a tree. It sprung into shape with just a tiny wobble to show anything had happened. I rode it slowly for about ten miles of dirt road to my truck.
The shop couldn't find anything wrong besides the wobble that they removed by truing it. I am a total newbie and I'm wondering if this sort of thing happens to others and if they keep using their wheels after it does.
I posted this in the cyclocross forum and it was suggested that I post it here for more insight.
