Bicycle Rim Bent Truing Stand Video

Deciding whether to fix or replace a rim can be a tough decision due to the cost. The price always becomes affordable once you have seen a wheel collapse at moderate speeds, and the damage that occurs to the rider. A rim-braked wheel has more urgency in this matter than a disc-braked rim, but "safe is safe". This video shows a rim in a truing stand with MORE than a half millimeter lateral wobble. For a rim to be considered "true" an 0.5mm deviation is the maximum. This rim also has it's issue in a short section of rim which indicates it is bent. This rim is beyond correction by spoke tension changes and should be replaced as imminent failure cannot be ruled out.
