The Tni AL22 rim has arrived!
It's a lightweight aluminum rim with a catalog weight of 380g.
The "22" comes from the rim height of 22mm.
There's also a 28mm rim called the CX28,
but that one has a catalog weight of 490g.
For some reason the manufacturer labels it as "for cyclocross."
Both the AL22 and CX28 come only in 32H specifications.
Personally, I think the AL300 rim (460g) is a better fit than the CX28,
so I reckon the AL300 is the way to go even for cyclocross.
Light rims often have disappointing seam precision,
but the AL22 is actually pretty good in this regard.
Let's ignore the fact that the sticker looks like old Fulcrum.
↑Well, I mentioned it anyway
Compared to the AL300...
The seam processing is identical, so I'd guess they're from the same manufacturer.
As for the weight that matters,
I got 377g, 376g, 377g, 391g, and 379g.
Hmm? There's one outlier in there weight-wise.
I'll exclude that one since I figured out what to do with it.
Generally it seems stable at just under 380g.
The other day I wrote that 32 CX-RAY spokes in this wheel's length would be roughly 149.6g,
but the actual measured value fluctuated between 149.7g and 149.6g.
The image above captures the 149.6g moment.
Since the hub is 32H, it should be lighter due to more flange holes, or so one might think.
If we use a rim estimated at 380g, the estimated total would be 608.5g,
so maybe we could squeeze a rim around 377g to get it under 599g.
No dice.
Well, even so it's plenty light enough.
Complete wheel makers would probably tout "catalog spec 590g!"
or something like that (laughs).
As for the AL22's almost-380g lightness,
the WH-7850-C24's WO rim measured at 382g actual,
and the R-SYS SL's WO rim measured at 385g actual (both front rims),
they're about the same weight at the outer edge as the lightest complete WO rims.
Complete wheels often make the rear rim heavier than the front (intentionally),
so the ability to build both sides with the same weight is a real advantage here.
In the past I've seen lighter WO rims like ALEXRIMS EST13 (measured 345g),
ALEX Crostini R3.1 (claimed 370g, measured 388g),
and NO TUBES ZTR Alpha340 (measured 348g),
but light WO rims often get heavier under the same name or get discontinued,
so the AL22 might meet the same fate someday.
As long as the measured value stays under 400g, I plan to keep stocking them.
More on the rear wheel and pricing another time.
