Question about truing a wheel on a rainy day in Portland
I tried truing my rear wheel after riding through some wet streets last week and the spokes kept pinging weirdly, has anyone else had trouble with moisture messing up spoke tension?
Moisture definitely messes with spoke tension, especially if your nipples are aluminum and corrode a little. The pinging sound is usually the spoke relaxing or sticking in the nipple as you turn it. A tiny drop of light oil on each nipple before you start truing will stop that noise right away. Portland rain gets into everything, so I'd also check that your rim tape isn't holding water against the spoke ends.
