Metron 45 SL Disc

A customer brought in a complete wheelset with Vision's 45mm high rim.

Starting with the front wheel.
Both front and rear wheels are loose, so they wanted them tensioned.
Rather than having an issue with the wheelset itself,
the problem is with this particular unit.
The customer rode a bike with the same wheels at some kind of demo event,
and didn't feel any looseness in that one.

The front wheel has a 2:1 lacing pattern

with an X crossing, and the final cross isn't fully woven.
The spoke-fewer side is laced radially.

By tension meter readings,
the values weren't particularly low.
If we were to completely rebuild it with reverse different-diameter lacing
and weave and tie the final cross, it would transform,
but I did as much as I could with just tightening.

Initially the rim was offset to the right by about one sheet of paper.
The image above shows the state after tensioning
as much as possible on the spoke-fewer side,
which is harder to turn when pulling from high tension.
From here, the spoke-more side can be tightened unidirectionally
until center is achieved.
Since the direction of the initial offset and the direction shifted afterward are the same,
the amount of additional tightening is visualized
by the one sheet of paper that could be pulled from the hub-side gap in the image above.

Achieved center through additional tightening.

The rear wheel received the same treatment as the front,
but this one was truly a loose unit.

Unlike the front wheel, this is a radial cross lacing.
The reason it doesn't look like a radial pattern
is that the spokes on the anti-freewheel side are tangent-laced,
so from the side view they don't pass through the final cross on the freewheel side.
Since I was showing the customer the work,
I didn't take photos with the centering gauge for the rear wheel.
The initial center was perfect, and through tightening the spoke-fewer side,
I first shifted the rim to the left,
then achieved center by tightening the spoke-more side.
The rear wheel transformed even more noticeably than the front.
