There is a separate thread on the mechanics forum about this with not much real info. My experience is that all bike wheel are unbalanced. This is most noticeable on the rear with the bike on a stand. If you crank up the rear wheel rpms the bike starts bobbing up and down in time with the rear wheel. It is not so noticeable on the front as it is hard to get the fr wheel moving faster than 10-15 rpm while the bike is on a stand. Although the stem is fairly light, the combo of stem and extra rubber around the stem makes for enough weight concentration for this to be noticeable on a bike on a stand. It is never noted by the rider will riding however. Some rims have a weight concentration where the rim is joined together, others dont.
