rear wheel shake
Today while commuting to school, I had to do some heavy braking, and the back of the bike stepped out for a bit. I didn't crash or anything, but it was a bit scary. I have had this happen once before, but I think I locked my rear tire up that time. This time however, I didn't hear any tire screeching, so I don't think I locked the rear.
I will have to look into this to see if it could be sign of something else, like mis-aligned rear wheel or something. I don't really know right now.
