Bonz, if you need a new hub I highly recommend them as the quality is very high especially the bearings as they feel as good as new!
Looking at the pictures again your middle part of the tread is very close to the frame compared to when I had mine. May be that your chain is too short?
Is this frame brand new aswell? As the quality on mine wasn't that high. The left Chainstay was shorter than the right in turn affecting the dropouts. You may need to change the wheel to compensate? If it's too bad maybe exchange the frame.
