Tni (Japanese rim manufacturer) has released three types of AL22W rims as derivative models of the AL22 rim:
AL22W (with brake zone / non-offset rim)
AL22W (with brake zone / offset rim)
AL22W (disc brake only, no brake zone / offset rim)
So I decided to stock them in.
Based on the rim height and specifications,
it looks like they're positioning themselves against DT's RR411 series.
First, let me show the ones with brake zones.
The AL22W models are all humpless tubeless-ready rims.
The reason the rim holes in the photo above look offset is because I photographed the offset rim version.

Next, the disc brake-only rim without a brake zone.
This one is also a tubeless-ready rim.
Just like DT's RR411db rim, the disc brake-only rim
comes in offset rim configuration only.
↑Actual measured weight
The AL22 rim's actual average weight of 385g (per our measurements) really is outstandingly light.
These rims actually arrived before they went up on the distributor's website,
but I figured it would be better to wait until they were listed, so I'm posting this today.
The actual measured dimensions for all rims are 21.8mm height / 24.4mm width,
but the spec says 22mm height / 24mm width, and the listed weight for all is 445g.
Whether we'll use these rims for nömu Lab Wheel #8 or #9 is still undecided.
I'd like to build a sample wheel (that's why I bought them),
but I just don't have the time right now.
The brake zone versions come in 20/24H front and rear,
and the disc brake-only comes in 24H for both front and rear.
For the disc brake-only rim, I'm planning to build with
Shimano 105's sparse-dense phased 24H disc hub.
The current 105 R7070 hub
comes in two hole counts: "32H" and "sparse-dense phased 24H,"
and the sparse-dense phased 24H, while requiring slightly more complex spoke length calculations,
can be built with 24H rims.
The spacing between sparse and dense holes in the phased pattern is exactly 2:1,
and by drilling holes at the midpoint between the sparse holes—the rest phase—
you get a 1:1 spacing, meaning evenly-spaced 36H holes. That's why
Shimano sells hubs with rest-phase holes in their sparse-dense 2:1 phased 24H format
branded as "36H" hubs.
I can already hear someone saying: "You're just arbitrarily interpreting the 36H hub as a sparse-dense 24H hub!"
And that's true.
But on the flip side, 36H rims
(the kind that would match 105 hubs)
are pretty hard to find among competitive-grade rims!
I can't think of any use for it other than using it as a sparse-dense phased 24H hub, so
that's why I keep using this roundabout terminology.
