i just got my 2004 switch back from the shop cuz my wheel would not spin freely. When I would stop pedling the chain would get all wraped up. but that is fixed now and i have another problem, my 8 inch hayes rear rotor is rubbing my frame! is this a big prob. or is my rotor just bent? the bike was bought just under a week ago and i have had 2 other problems with this bike. :nuts: I Am Pissed! is this a big prob or not?
