So I just got a Gary Fisher Advance Disc about a week ago(my first real bike that's not from walmart). I've taken it out 3 times for a total of 12 miles and the paint it rubbed down to the frame already in 3 places where the cables hit the frame. Is this a warranty issue? I feel like 3 rides is too soon for this to happen. I understand normal wear and tear, but this seems like too much wear for the amount of use.
