diagnose a wheel
I've been tasked with fixing my lady's wheel, but I'm trying to figure out what's wrong with it before making it worse. It's seriously (easily a full cm) out of true right where 2 adjacent spokes (adjacent on the hub, not the rim) are badly bent, and the bent spokes are basically under zero tension. What's got me stumped is the rim -- it's pulled towards the hub with the loose spokes at the point where they connect, whereas I figured it would pull away from that hub.
Perhaps the biggest problem here is we don't know what happened to her bike. Seems likely someone drove a car into it while it was locked up, but it's hard to be certain exactly how the damage was done.
One more observation -- the bent spokes straddle the seam in the rim. I looked for cracks and didn't see anything, but maybe this is important? Or maybe it's just a coincidence.
Any thoughts on how to proceed? Are the spokes/nipples toast? Does the rim need to be banged out flat(ish) before I try to get it true/round? Is the rim a loss? Thanks for any advice. BTW, I've built and trued wheels in the past, but never had to fix a seriously damaged wheel.
