Hello all. Got some new tyres and after putting them on i noticed that my rear wheel is about 5 - 10mm to the left. not due to being out of adjustment but out of allignment. my question is, am i silly and it is supposed to be like this or is there a possible issue. the bike had a standing drop to the left before i got it but wouldnt think it would have caused it. all spacers and so on for the wheel appear to be as per the book. rear swingarm has never been removed as far as i can tell. could there have been enough force in the bike falling to bend the frame at the rear.. thanks in advance.
