I received a Racing 5 DB from a customer.
They requested an inspection. Let me start with the front wheel.
Almost no runout, with just a slight centering offset.
Based on the amount of dish at the rotor adapter, it's a 2:1 spoke ratio build, and
uses an offset rim.
Since the side with more spokes is the rotor side, there shouldn't be any issues.
Next, the rear wheel.
There was one spot with lateral runout that the customer mentioned, and
this one also had a slight centering offset.
Since there's no brake zone, there's no cutout finish for that either,
and the rim seam step is quite noticeable.
I worked it until "lateral runout is completely undetectable except at the rim seam,"
and the customer observed the process.
It's quite an unconventional spec—few spokes with radial lacing on the side with the disc rotor.
However, the flanges are quite robust relative to each spoke,
so they're designed to prevent brake torque from transmitting to the spokes.
Unlike the Zonda DB, it's not a left-right reverse asymmetrical diameter build.
There's no brake zone, and stickers are applied across almost the entire rim circumference, but this is problematic.
For applying the centering gauge, there's no phase where both sides lack stickers.
If there's only one side, there are unstickered areas like the valve hole phase in the image above.
If I measure one side from sticker-to-sticker and apply the other side sticker-to-rim,
it could look like a centering offset, so
I applied the gauge using the sticker phase on both sides.
