My rear (disc) wheel currently has a lot of movement in it. I have been riding it like this for 18 months due to intending to replace the rim (has been dented) rather than simply getting it trued. The movement has worsened but nothing else really noticeable has changed.
So I am now considering what are the impacts of ignoring a buckled wheel and continuing to ride. These must sit on a spectrum from ride comfort through to catastrophic failure but I don't understand what they are. There also in my mind be an impact on ride speed or additional energy expended by I can't quantify these.
What is the impact of a buckled wheel?
