A customer brought in a Scirocco H35MM for service.
It's called that because it's a Scirocco with a 35mm rim height, but
I find it odd that they write millimeters as "MM" instead of "mm."
But since the official name is SCIROCCO H35 MM, there's nothing I can do about it.
The front wheel only needed a minor truing adjustment.
The rear wheel—according to the customer—is noticeably loose on the freewheel side.
I felt it before starting work, and yes, it's a bit loose.
However, it's at the lower end of what would be acceptable at factory standards,
not the kind of looseness you'd call abnormal or defective.
The rim had shifted toward the freewheel side, so
I tightened the nipples on the freewheel side only
and trued the wheel while centering it.
Even though I didn't touch a single spoke nipple on the non-freewheel side—not one—
the spoke deflection clearly decreased.
The customer confirmed this as well.
When you tighten just one side, the entire wheel becomes more tensioned,
so spoke tension on the opposite side increases—both theoretically and from experience this is certain,
but it's unusual to feel such a dramatic improvement here.
I wouldn't say the centering was that far off to begin with.
On the front wheel, treating the side with the bearing adjusting cone as the left side,
the Campagnolo sticker on the hub shell is
upside down when viewed from the direction of travel.
The rear wheel that pairs with this one had the sticker on the hub shell facing the correct direction, so
I thought I'd remove the hub axle and reverse the sides,
but it didn't work out.
↑This is a Zonda front hub, and
they fit a plastic cover into the groove part to snap into place,
giving the hub shell end a smooth appearance.
As for that cover, it accommodates the difference in left and right diameter at the cone nut area—
the outer diameter of the cover is the same, but the inner diameter is different.
Since the hub shell itself is symmetrical left to right,
you can change the hub shell orientation by removing the cover and reversing the axle direction.
But with this Scirocco, even the cover part is integrated as part of the hub shell, so
left and right can't be reversed.
When a hub sticker is applied upside down,
there's no way to change the sticker's orientation except by attempting to peel it off.
