Wheel very close to right side chain stay
On my Cube LTD Comp when switching between slicks and nobbys, I have noticed that the nobby rear tyre is virtually rubbing against the right side chain stay, ie the one on the other side of the derailleur. The wheel itself isnt buckled or bent in any way, and I can only think that it was built like this.
When I am cycling uphill, being a rather large bloke, the bike sways from side to side, and I can hear the tyre rubbing on the right chain stay.
What can I do to fix this problem?
