Re: Rear wheel, spokes and bearings
Hard to tell from the pics but it looks like you are not using rubber on the inside as well as the outside. I did this for a few months and found that the spokes were breaking. If this is not the case in your build , could your chain be rubbing in just that spot as the wheel turns? Is your chain clean and shiny anywhere along the inside of the chain?
From the looks of your spoke, you are losing the head off the spoke, that is strange indeed. I drove all winter with 4 missing spokes and one spoke is not such a big deal but I know that it bugs you and you would like to figure it out. What I noticed is that the area that the spokes cross each other is being strained as our sprocket gets tightened up. This tends to make the spoke want to pop away from the hub.
