I was feeling pretty good, having just changed the headlight bulb and was backing my bike out of the shed for a Christmas day ride. The right mirror touched (and I'm talking TOUCHED) another object and the mirror just popped off. Evidently this is not the first time, since the previous owner had secured it with a zip tie so it would not crash to the ground. I didn't want to manhandle it too much and risk further damage. Is there an easy way to re-secure the mirror?
