A customer brought in
（↑I don't usually post photos here,
but with Mavic wheels I often snap pictures in this spot
to record the model names）
both front and rear wheels for service.
The rear wheel was rubbing the brake shoe, so
the customer wanted it trued if possible.
Since the brake zone is Exalite,
it's easy to notice the rubbing by sound,
but it's not constantly dragging—
it only rubs in specific out-of-saddle situations.
The wheel had almost no center offset, so I
tightened the freewheel side with extra tension
to shift the rim as far right as possible,
then centered it using extra tension on the non-freewheel side.
However, the customer says they haven't set the gap between the brake zone
and brake shoe too tight, so based on how much I could tighten,
I think there's a low chance the rubbing will improve completely.
Next, the front wheel.
They said they brought it in as an "afterthought" to the rear wheelfrom Gunma Prefecture,
but this one was in much worse shape.
Unlike the rear wheel, it showed signs of
being fiddled with repeatedly in attempted truing work,
the wheel center was seriously offset.
Yet the lateral runout still wasn't fully corrected.
In that previous image, the side where the dial gauge has clearance
is the side with the 6-hole cone adjustment,
which you can tell from the photo rangeI deliberately shot to show.
The radial runout was terrible too—when I spun the wheel,
the rim was eccentrically wobbling all over the place. I showed the customer
what the wheel looked like before correction.
From there, I dialed it in so that only at the phase where the rim seam
slightly bulges outward does the dial gauge just barely kiss it lightly,
with zero radial runout everywhere else—the customer watched this whole process.
Fixed the lateral and radial runout and centered the wheel.
I asked if they'd been riding with that much center offset all along,
and they said they weren't the original owner—
they'd only used it for 2 or 3 days.
I found a defect on the front wheel that I pointed out to them (won't detail it here),
something that probably made the original owner let it go.
I suspect they tried to fix it through attempted truing work,
but that's likely what led to all this mess.
