My rear wheel went out of true recently, and armed with a spoke key, some blue-tack and a pen, I tightened the half-dozen or so very loose spokes and trued it, pretty well I thought for a beginner.
But it's warped again and some of the spokes are very loose within a couple of weeks. Clearly I need to tighten the spokes much more to keep them tight, but I would have thought that would warp it.
So what's the approach? Tighten hard and try to true from there? Any advice appreciated. It's a 29er, if that makes any difference.
