egg-shaped rear wheel!
i went over a few potholes at high speed the other day, and i've noticed it's bucked my rear wheel. theres not a great deal of movement from side to side... but through a rotation, the tyre moves closer to the frame, then back again, whilst staying in an almost straight line. it's as if different sections of the wheel have different radiuses.
is this common in mid range mountain bike? the rims are Sun - Black Eye
is this something i can fix with a wheel truing tool? i've only trued a wheel once before, and that one was moving from side to side.
cheers.
