Another day of wheels (and so on...).
A customer brought in the front and rear wheels of a DT P1800 Spline.
The image above is just the front wheel.
There were circumstances requiring a rim replacement on the rear wheel,
which is why they brought them in,
but both front and rear wheels had severe brake zone wear,
so we decided to replace the rim on the front wheel as well.
Since the rim height is close to the Nomunolab Wheel No. 5 rim,
I thought we might be able to transfer the rim with the same spoke length,
but without absolute certainty,
I decided against transferring the rim and instead measured the inner diameter of the old rim.
The difference in diameter was only about 0.2mm,
so I confirmed that we could do the rim replacement with the same spoke length.
The hub is a DT 370-grade spline 20H.
Spline refers to a straight-spoke hub flange in DT's lineup.
↑Regarding the spline,
I made a correction based on comments I received.
In the image above, the hub shell marking says "DT SWISS,"
but the marking on the opposite side says "spline,"
so I'll photograph the rim after rebuilding from that side.
The spokes are not DT's Aero Comp, but rather
Aero Comp Wide—
a model used exclusively in pre-built wheels.
Unlike the Aero Comp, with a width of 2.8mm,
it won't fit through the standard round holes in most hubs.
But with this hub, the relationship between the spoke head and
the hub flange is "hook-style," so
there are no dimensional constraints on the butted section.
The nipples were black Squorx, and they were what I call
"bare Squorx"—used directly on the rim without PHR washers.
I tell my customers that "I reuse any parts that can be reused,"
but I don't want to use bare Squorx nipples or Squorx nipples with PHR washers
on the Nomunolab Wheel No. 5 rim,
so I'll go with DT 12mm aluminum nipples instead.
Squorx nipples are 15mm long,
which is because the Torx-profile Squorx grip area
adds 3mm to the back of a 12mm nipple,
so the effective length of the nipple itself is
roughly the same as a 12mm nipple.
So, when the wheel is complete, if the spoke end reaches
the end of the Squorx nipple,
that means the spoke is too long.
As in the image above, this wheel had the proper length.
If it were on the long side, I would consider the rim inner diameter difference
and cut the spoke a bit shorter.
Built.
