I love this post. I am a mechanical engineer but not an expert for sure on this but I have a good theory. It is moving due to vibration of the fork as you travel down the road. The vibration of the fork will occur moving the fork normal (90 degrees) to the angle that it connects to the hub. This vibration will create acceleration and forces on any mass that is not centered at the hub. My theory is that it wants to line up with the fork which is the center of the vibration, not because of the cable.
All that being said, you could put a long bolt in the unused eyelet on your fork to hold it in place or keep it from moving backward. The mining industry uses vibration like this to move ore across screens and to onto belts and conveyors. Here is a company that makes really big vibrators. https://welco.ca/files/joest.pdf On Wednesday, January 27, 2016 at 6:05:46 PM UTC-7, MattB wrote: > > Last fall I built a new front wheel for my Atlantis with one of the > Shutter Precision generator hubs, best thing I've ever added to my bike by > the way, but I've been experiencing an odd phenomenon with the electrical > connector.
