Giant factory wheels are crap anyway. Go to Wheelsmiths and drop $100 on a new wheel, one with a freehub instead of the stock (probably) freewheel, it'll last forever. The front rim will be OK as is. My stock rear on my Giant Cypress broke about a dozen spokes in the first 1400 miles, before I built a new one. I just bought new spokes and a new rim and laced it myself using Sheldon Brown's how-to page, and it lasted OK but about 10,000 miles later the axle broke and I wound up buying a new wheel anyway. If you're replacing the whole thing including the hub, I found that there wasn't much price difference between buying the parts and just buying a built wheel.
