A customer brought in wheels for rim brakes on a DT (DT Swiss) Mon Chasseral (a lightweight mountain model),
and the rear wheel was loose or had some play, so they asked me to fix it.
The rear wheel was indeed loose with some play.
The rim had shifted to the left side (non-drive side),
and when I asked the customer about it,
since this was the first owner of the wheel with no truing history,
it must have been misaligned from the start.
The hub and rim have "Mon Chasseral" written in script—
this refers to Chasseral mountain in the Jura range
(though "Chasseral" is the more common spelling,
I'm following the "Chasseral" notation used by Japanese distributors
for this wheel model name).
The previous owner had done spoke truing with emphasis on tightening the drive side,
shifting the rim left by twice the original offset amount to the right,
then centering it with non-drive side tightening—
resulting in a final state where not a single nipple went untightened.
This wheel actually has pretty good left-right tension balance,
part of which is due to the 2:1 spoke pattern,
↑drive side Aero Lite
↑non-drive side Aero Comp with
a counter asymmetrical build
using reversed different-diameter lacing.
I didn't photograph it, but
the front wheel was all-black Aero Lite.
Mon Chasseral currently only produces
wheels for disc brakes, but according to
Japanese distributor catalogs,
both wheels are listed as all-Aero Comp.
However, checking the manufacturer website showed
Aero Lite / Aero Comp.
Surely it's not that the front wheel is all Aero Lite
and the rear is all Aero Comp.
Since the disc brake version has symmetrical lacing on both wheels,
they likely use standard reversed different-diameter lacing.
The claimed weights are 578g front and 688g rear for a total of 1266g,
and while this spec-only approach doesn't resonate with those
who choose wheels based solely on published numbers,
I appreciate that they've put better engineering inside.
For the rear wheel, though the design saved on rebuild work,
this time I only did the tightening without tying in the spokes.
