I managed to fall off my bike while riding through campus today. I didn't realize there was a raised ledge to my left and my wheel hit it and I managed to jump off while my bike was falling. After a quick check, everything seems to be fine. The fall wasn't hard or anything, and the only noticeable difference was that my brake lever was shifted a bit (which was an easy fix).
However, while riding, my bike felt a lot more "wobbly." It was more difficult riding in a straight line. Did I probably mess up my wheel? Would truing it fix it? Is it possible to true a wheel without a truing stand?
