I take that back... On the Dura-Ace wheel it was the drive side, on the Ultegra wheel it was non drive side.
Having looked at the Dura-Ace wheel I can see that at some point I must have thrown the chain over the lowest (largest) cog and into the spokes as the outside flange spokes were all chewed up. That's right wear the spoke broke so my guess is that's the problem.
So I figure lets do an experiment, I sanded out the burs on the chewed up spokes and stuck another spoke of the proper length in there and also in the Ultegra wheel and trued them both up. Rode the Dura-Ace wheel into work this morn.
I will mark it on my calendar and we'll see how long they last
I know rebuilding is the right thing to do but I got to get the house painted, the car fixed, and a new lawn mower. So some things have to wait
