How do I fix front end wobble over 40mph if I let go of the handle bars ? The front tire is about warn out . I wouldnt have known it does it . But today I had some one run up on my rear end and wouldnt get off me till I got in the other on coming lane so the person would pass me . After they passed I raised my hands to gesture whats your problem . And as I let go it wobbled . Ive only own the bike for 2 weeks so Im still working the bugs out of it . The wheel bearings are good so are the stearing stem bearings .
