I received a WH-6800 (Shimano wheelset) from a customer.
Based on the sand buildup around the hub flange and fine sand coming out when I spun the rim,
I guessed it had been used for cyclocross, and I was right.
The customer said it had quite a bit of runout,
but when I checked the rear wheel first, it had no centering issues and almost no runout at all.
The front wheel had considerable runout and was apparently rubbing on the brake shoe.
↑ There were buckling marks on the rim.
From a slightly angled view
I couldn't fix it perfectly,
but after the work, I mounted the tire and installed it on my own bike,
then took it for a test ride while adjusting the brake shoe contact,
and found that by feel the braking was barely affected,
so there's basically no problem.
Going beyond this point would require rim replacement,
and that would get expensive,
so I think I've done the best I could within the scope of excluding that option.
