I took in a ZIPP 404 and 202 from a customer.
I checked the front wheel too, and there was just a slight wobble that I corrected—nothing serious.
According to the customer, there was suspicion of a centering issue on the rear wheel of the 404,
but among the four wheels (front and rear on both the 404 and 202), only the rear wheel of the 202 had any centering deviation, and it was minimal.
The reason the customer suspected a centering issue was
"the spacing between the brake shoe and the rim was different on the left and right,"
but that turned out to be a direct-mount brake setup issue, not a wheel problem.

It looks like the flange ring has been removed from an older-style hub with a flange ring design.
