If you have a bicycle wheel that is out of round, there are a few things you can do to true it. First, you will need to identify where the problem areas are. You can do this by spinning the wheel and looking for places where it wobbles. Once you have found the problem areas, you will need to adjust the spoke tension in those areas. To do this, you will need to loosen or tighten the spokes in those areas. Finally, once you have adjusted the spoke tension, you will need to re-check the wheel for trueness.
