A customer brought in a Shamal Ultra for service.

Starting with the rear wheel.
There's definitely a history of truing work done on it (I confirmed this with the customer too),
and while the lateral runout was corrected pretty well,
it came at the cost of significant radial runout.
Unlike the nipples on the front wheel, the corners here were all gouged up,
it looked like someone had just been touching it everywhere.

Looking at the brake wear marks on the rim spinning up and down,
the pattern traces a true circle without wavering—



I managed to get it to the point where there's almost no radial runout in the brake zone
and the wear marks stay true. It took about as long as building a Nomulab wheel front.


The G3 spoke with the magnet mounted on it had the worst phase shift,
jerking outward radially,


and the brake shoe was even digging into the label.

The front wheel just needed a bit of light truing.
