Iro Ikkai Zutu (sic)
It means "one color at a time,"
but the proper writing is "Zutu" not "Dutu".
To be more precise, it's "Iro Ikkai Su゛tu......" but anyway.
It's not that I can't distinguish between Du and Zu,
because when encountering monsters it says "Nanika Chikazu゛itekita!"
and after battle gold acquisition it says "○○○ Zu゛tu no gold wo mitsuketa!"
So what am I talking about?
The Black Onyx.
By the way, none of this has anything to do with this wheel.
Anyway, today it's wheels again (etc.).
WTB's lightweight low-profile carbon tubeless offset disc rim
（↑way too many attributes）, the CZR i23,
I built a front wheel in Cannondale Lefty standard.
Since it's a Lefty, saying "front wheel" is obvious,
but I mentioned it anyway for good measure.
ONYX Racing Lefty standard hub, 24H
All-black CX-RAY 64 spoke reverse Italian pattern lacing.
I'll tension the spokes later.
This rim is for gravel and comes in 24H and 28H options.
The wider CZR i30 rim designed for MTB
comes in 28H and 32H options instead.
I'm not entirely sure why, but disc brake hubs have
this "stubborn 32H only" problem.
For disc road bikes you'd want 24H, and for 29-inch lightweight carbon rims
around 28H seems best,
but the R7000 series 105 hubs come in 32H and 36H options.
Especially 36H—it's actually harder to find rims for that.
MTB carbon rims from DUKE, Stans, and others do have
28H specs available,
but BOOST standard hubs are overwhelmingly
32H spec only.
Shimano's M9100 series XTR and M8100 series XT do
have 28H specs, but for rear hubs,
in racing environments, apart from those used for political reasons,
self-funded buyers are so rare they're practically urban legend
（though admittedly more sighted than Japanese wolves or baked tanuki）
—they use Microspline hubs—so
a lot of customers exclude this as an option（※）.
※Current SRAM users, and people running Shimano 11S now but planning to switch to SRAM next,
plus folks who have M9000 series e-bike component infrastructure wired through their frame
and are waiting for 12-speed e-bike MTB components.
This hub's bearings are 6805 standard size,
inner diameter 25mm, outer diameter 37mm, thickness 7mm.
The bearings that went into early Hollowtech II BBs like the SM-FC7800
are also 6805, and since the inner diameter is 25mm
but the crankshaft outer diameter is 24mm,
the dust cap/downsizer plastic spacer on the BB
reduces the inner diameter to 24mm.
Campagnolo's Ultra-Torque bearings are
6805-based with only the thickness reduced by 1mm as a custom spec,
and since the Ultra-Torque crankshaft outer diameter is 25mm
the shaft and bearing contact directly.
The rim sticker shows a maximum spoke tension of
135 kgf, but aside from the spokes (CX-RAY) themselves,
the nipples and hub look sketchy, so I didn't tension them to the absolute limit.
Still, I tensioned them higher than most wheels.
The rim holes on the inner side have reinforcement,
and on this offset rim there's clear hole offset too.
WTB's proprietary stretch-band rim tape, Solid Strip,
which neatly fills just the bead ledge groove, came included.
This rim isn't nearly as insanely light as
Stans' Grail CB7 rim at under 300g,
but considering the high max spoke tension and offset rim design,
it's a genuinely light rim.
The Crest CB7 with the same inner rim width is
nominally 325g with a limit tension of 105 kgf,
and compared to that, this rim's overall performance specs are better numerically.
That said, I'm not telling you the actual weight of this rim.
↑Wow, what a jerk!
Sorry for the wait!
