I noticed recently that my handlebars seem to have some kind of self centering function. What I mean is if I lift the front tire off the ground and turn the bars side to side there seems to be some type of mechanical catch which holds the bars (and front wheel) exactly in the center position (as if to ride in a perfectly straight line). I have never noticed this before and would suspect a damaged bearing except for the fact that it alligns in a PERFECTLY centered position as if the bike were designed this way. Is this normal? It is a Diamondback wildwood.
