I've noticed a slight "growling" sound and vibration in the handle bars when going around curves at 40-45 mph or more on my trike.. Almost reminds me of a rough bearing. I haven't checked the bearings yet, but the wheel spins freely without and noise or roughness. Anyone have any ideas? Not sure if this is normal with this light of a front end and the narrow tire. I've never run one this light on the front. I've attached a pic of the front end I have.
