I recently re-installed my rear wheel after getting a new tire mounted. I noticed that the belt was pretty close to the sprocket flange but not touching it (less than 1mm). I had a plan to loosen to axle and reposition the belt on the center of the sprocket this weekend. I took a 100 mile ride yesterday and much to my surprise, the belt had moved itself out the center of the sprocket (in spec).

Should I be happy the belt repositioned itself or is this an indicator that something is not correct post-wheel reinstall?
