Tni's AL300 rims are arriving in large quantities the day after tomorrow.
I'm planning to build a bunch of Nomu Lab wheels #1.

I personally only had one 20H wheel, so
I'm planning to build a rear wheel with 24H.
I disassembled the 20H rear wheel and rebuilt it as a front wheel today. That's what the image above shows.

As for the 20H rear wheel, there was no problem even with my body weight of 72kg.

There were also wheels built with Cosmic Carbon rims on regular hubs,
but that rim just has a carbon fairing on it,
and the rim dimensions are almost the same as the Open Pro.
Apart from aerodynamic characteristics, if you look at it as a wheel structure,
it's almost the same as a wheel built with an Open Pro 20H rim (which doesn't actually exist).
For more details, please check the previous article (→here).

The AL300 rim has a higher rim height, so it builds up more solidly than the Open Pro.
I didn't feel any anxiety using the 20H in actual use,
but the 24H provides more peace of mind,
so for my personal wheel and the #1 stock build, I'm going with rear 24H.
If your body weight is under 60kg, I'd actually recommend the rear 20H instead.
