I just finished working on just such a wheel. I replaced a half dozen nipples, and could easily replace the rest, were it not for the fact that there is a small crack at one of the spoke holes. My wheel was/is out of round. I learned a lot in the process, and hope to get another 200 miles out of it before my visit North is over and I head back home. It's original equipment on an 87 Schwinn Prelude.
