I had similar issues. ?New Michelin road classic tires did not help. ?I did fit a stabilizer and it does help a lot. ?There is some wobble at higher speeds but very dependent on highway rain grooves. ?On my bike, I think the wobble may be more about the highway rain grooves (I live in San Diego). ?Seems to go anywhere I need to take a highway. ?
