A customer left a Shamal Ultra DB with us for inspection.
To be more precise, an old acquaintance of mine brought in a wheel that someone else had entrusted them with for our shop to inspect,
so the person who brought it in and the actual wheel owner are different people.
The disc brake version of the Shamal Ultra
comes only with 2WAY-FIT rim specs.
The rim has a sticker noting this,
but it's not prominently displayed in the catalog model name.
Though these days, clincher rim wheels often come tubeless-ready
without any special mention.
Let me start with the front wheel.
When I first used a centering gauge, there was a slight center deviation,
but I couldn't see it in the image above.
That's because there's lateral runout.
The wheel was wobbling in a way you'd never expect from a Campagnolo stock wheel.
↑This is the end on the side with the rear wheel's bearing adjustment nut
(left side / non-freewheel side).
The centering gauge contacts not the hub axle itself
but the overlaid end piece.
↑This is the end on the front wheel's bearing adjustment nut side
(right side / opposite the rotor mounting side),
where the slightly protruding silver hub axle end
from the black part contacts the centering gauge.

Aside from the runout, there were characteristic grip marks
on nearly all the spokes.
These are marks that would absolutely never appear if the plastic stock tool was used.
Based on the initial lateral runout and these marks, I suspected that someone
had done some amateur spoke truing after it left the stock state,
so I asked the person who brought the wheel in about it.
Since they're not the owner, they didn't know the detailed history.
Based on the rim and freewheel body condition, it's certain the mileage is zero.
Next, the rear wheel.
No center deviation, and while there was runout,
it wasn't as severe as the front wheel.
Better than the front wheel, but still has those characteristic grip marks.
On the rear wheel, due to G3 lacing geometry,
the rotor mounting side uses radial lacing,
and to achieve this unusual spec, the flange design is quite intricate
for just one spoke.
The spokes appear the same width from the side,
but on both wheels the fewer-spoke side of the G3 lacing is thicker—
it's an "asymmetric lacing counter with reversed different-diameter lacing."
Measured with calipers, the more-spoke side is 1.5mm thick
and the fewer-spoke side is 1.8mm thick.
The image above shows the 1.8mm thick spoke fitting perfectly deep
into groove A of the stock spoke press tool,
but it won't fit into the narrower groove C.
The 1.5mm thick spoke fits perfectly into groove C.
As long as you're using this tool,
those kinds of marks shouldn't appear on the spokes . . .
