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.

Do you mean the rubber to mount the sprocket? Yes I use both, just did not have it on for the pic. And yes it always break's the head of the spoke; i have that spoke marked and it is alway's that spoke that break's. My spoke's were just fine when I left, I rode a long way's with the broken spoke and now that I have gotten home the other spoke's look like they have been stressed. I have no ideal what's going on and I'm sick of fixing spoke's. My chain does not rub anywhere.

Is the spoke a little bent in the area that two spokes cross each other? As the sprocket is tightened it puts a strain on the spokes making the spokes tighter than they were when you begin the install. A bent spoke becomes shorter/tighter, if you know what I mean. From looking at the pics..two and three...that "X" is close to the rubber. I wonder if you should wait until the sprocket is installed before "truing" the spokes. I know this does not address the fact that it's always the same spoke but it's all I can offer.

Thank's toytime for your input, but no spokes are bent; it just look's that way in the photo. Don't know what I'll do, I don't have anymore spoke's so I'll have to ride my pedal bike to work tomorrow.

Just drive the darn thing, I just paid $28 for a new wheel and find that my rear wheel lasts me about six months anyhow.

I got heavy duty wheels from Husky Bicycles- 11ga spokes that are almost 1/8" thick. Quality steel rims. $82.00 delivered to my door for front and back together.

Maybe there is a burr or other sharp edge in the hole where the spoke goes through?

Also, have you tried using zip ties at each crossing of the spokes? It tightens up the wheel quite a bit for the half an ounce that it adds to the wheel.

i will be mounting my new sprocket on a disk brake mount and will let you all know what i think. i really do think it will be the hot ticket for motorized bicycles. the sprocket will be mounted alighned perfect this way without mounting on the spokes
