Another day of wheel work (and so on).
Unrelated to the title, but DT has an XR331 rim.
Probably the lightest rim in the XR series, which stands for cross-country racing
(all-mountain uses the XM series),
and this rim alone has unusually narrow width
—almost the same as the slightly wider rim for disc road bikes.
Actually, the minimum recommended tire width is also 25C,
(since it's still an MTB rim no matter what),
and if the minimum spoke count of 28H isn't a problem,
29-inch, which is 700C rim, can also be used for disc road or cyclocross bikes.
It's lighter than the same company's RR411db disc road rim.
Like the RR411 series, the XR331
has its rim sticker offset by 90° between left and right.
It doesn't affect performance, but if you care about appearance,
when the valve phase is the same on front and rear wheels,
it's best to pay attention so the relationship between sticker and valve is the same.
The offset rim of RR411 (for rim brakes)
has "no sticker directly below the valve when viewed from the freewheel side (right side)," and
based on that, when building both wheels with XR311 rims, I follow the same principle.
I received a DT XR361 rim from a customer.
This rim also comes in 27.5-inch size,
but these are 29-inch specification (700C).
It's the second-lightest rim in the XR series after XR331, and from here, rim width increases dramatically.
Or rather, XR331 is just too narrow for an MTB rim.
The XR361, unlike the XR331 and RR411 series,
has the rim stickers aligned at the same phase on both left and right.
This makes it easier for centering gauge work since
there's a wider range where you can apply the center gauge.
This rim, as you can tell from how the "361" marking appears in the image above,
is an offset rim, unlike the XR331.
I built the front wheel.
Chris King R45D hub 32H
all-black Compé Lodève spokes, reverse Italian lacing with no spoke pattern, and
black Squorx nipples.
Since the hub uses a quick release rather than through-axle,
I believe it's intended for cyclocross.
For this wheel, the hub, rim, spokes, and nipples (the rim came with silver nipples)
were all customer-supplied parts,
but I was surprised that the spoke length was spot-on.
With Squorx nipples, I apply a correction value to the calculated length,
and it turned out to be the same length I would have calculated.
Whether this is coincidence or not, I'm not sure.
