I am in the same boat, I bought a surface 604 boar hunter and have had issues right off the start . The chain rubs on the rear tire when in the lowest gear,there is a rubbing noise coming from the rear hub
the headset gap is to big. I ordered the bike online and this was how it came I talked to the person who i bought the bike from and he said to bring the bike to my local bike store and have them look at it.
I also phoned surface 604 help line and they said the same thing take it to your local bike store.After spending over $3000.00 on this bike this is the way they are dealing with my situation.I will be charged from the bike store for looking at these issues but was told that it might not be a warranty issue Wow not happy at all just getting the run around.
