To Jims point, is it shimmy or vibration coming from the dynohub? The latter does happen to me sometimes but only at certain speeds, someone way smarter could tell why due to harmonics and magnetic polarity. I would think going back to tje original front wheel would be a good place to start. On Apr 22, 2013 1:50 AM, "Cyclofiend Jim" <cyclofi...@earthlink.net> wrote:
