Strange thing is happening, when the bike is stationery, the wheel is perfectly fine, straight and in the middle of the drop outs, but when I start pedalling, after about 30 seconds the wheel is being pulled round so the tyre is rubbing against the side of the frame. I've done the usual, checked that the nuts are tight, and all seems fine. Frames not bent etc. I've recently changed the mudguards, but this shouldn't have any effect as the wheel was not moved / touched.
it's really irritating me now, tried taking the wheel off and putting back on etc...
