Next up is the Aero 80.
I felt relieved just hearing "you can tension it up to 120 kgf".
Since this rim has few constraints when building wheels, I was able to build it without much deliberation.
The rim has no published weight spec, but my actual measurement came to 525g.
While the rim itself has no published weight, the wheel as a complete unit has a published rear weight of 890g.
This wheel is a custom order that happens to use the same spokes as the stock version (CX-RAY), and it came in at an actual 902g. Since the spoke total length is longer on this one, accounting for that, the individual variation in rim weight appears to be negligible.
The 80mm rim depth gives an internal rim diameter almost identical to a 24-inch WO (wired-on) rim with around 20mm rim depth.
Also, the maximum specified spoke tension of 120 kgf is about the same as many aluminum rims.
In other words, to put it bluntly, you can think of it as "building a 24-inch aluminum rim". Since the rim depth is so high, there's virtually no rim deformation from spoke tensioning. Considering that, aside from the internal nipples, there aren't really any difficult conditions for wheel building.
20H would have been fine, but for a criterium bike prioritizing stiffness, I decided to go with 24H. Since we're at it, I'm going with 4-cross lacing—the privilege of 24H and higher spoke counts. I'm still undecided on crossing the spokes—maybe it's not necessary. I'll consult with the customer.
I can't say this out loud (well, you can read it quietly),
the sticker peels off.
I want to write about pricing.
The nomilab Wheel No. 2 front wheel and TNi Carbon 38 front wheel have the same spec except for the nipple, but No. 2 is ¥43,000 including tax, while the TNi stock wheel is ¥48,300.
So it seems we can sell a built-up wheel more cheaply.
Personally, just passing a stock wheel from right to left isn't interesting, so this is where the customer's interests and mine align, you might say.
For the stock wheel built with the TNi Aero 80 using TNi Evo hub + Sapim CX-RAY spokes:
Front wheel ¥61,950 including tax
Rear wheel ¥68,250 including tax
That's ¥130,200 for both, but ¥126,000 if you buy them as a set.
The rear wheel I built this time with the Aero 80 has the same spec as TNi except for the nipple, and the calculation shows:
Front wheel ¥53,000 including tax
Rear wheel ¥56,000 including tax
we should be able to sell them at.
This is for the Sapim CX-RAY spec, and if I build it as a nomilab wheel, I'm thinking of setting it up rear-wheel only—for people who already have tubular wheels and want to swap just the rear wheel for a flat-ground sprint-specialized setup.
This time's wheel is 24H because I really wanted to do 4-cross lacing, but I'm also thinking it'd be nice if I could sell the rear wheel at around ¥53,000 by going with 20H instead and using straight (round) spokes on the freewheel side.
