Sorry to say that this is yet another myth that has been debunked in recent years. I'm sure there are others on the list that can explain it better than I can, but weight is weight regardless of where it's located. A heavier wheel will indeed take a bit more energy to accelerate, but will keep it's momentum better. For climbing, a lighter will help, only because it reduces overall bike weight. An ounce on the rim is worth an ounce on the frame. This has been much discussed on other forums.
