Well, the lbs mechanic helped me, and the Giant rep was sympathetic... they are going to take care of my issue. I *think* they ordered a new wheel set, but I'm not totally sure... maybe just rims. Whatever addresses the seam issue. Didn't get the full details. The mechanic told me that the rep ordered the parts, and they would be on their way to the lbs in a few days if all goes as planned. I will be responsible for the labor as I expected from the phone call. Hopefully that will take care of my girl. Ugh, these sort of things stress me until "the fat lady sings".
