...Also curious to hear if the frame has held up well!

I didn't know it was available again, that is a great news!

I've built a few dozen of them, not a single issue reported.
And I plan to have a week ride with it in Croatia next month 

6 years used, quite a long time
We don't make that FHR930C rim any more, maybe you can replace with YHR930C rim without spoke holes.

Yes, 6 years ! And of hard riding, that speaks about the quality of your products

Does the YHR930C has the same ERD as the FHR930C ?
So I can reuse the spokes.

I have a BB92 on my FM-936(same as BB86 but 6mm wider) while I had ordered it as BSA.
Being heavily Hambinized at the time, I was very disappointed(big spindle in small hole = very bad  )
But installed a DUB spindle anyway as I had it already.

After a year plus with the SRAM BB86/92 DUB and a heavy usage, races and mud, it is still surprisingly smooth.

On other bikes I tried GXP, BBinfinite(similar to Hambini), BB30, PF30, Wheels mfg and some Aliexpress PF by screw.
On all of these I was changing the bearings once or twice a year.

Moral of the story... for a DUB I would go every time with the SRAM, it is cheap and reliable.
And maybe look for something else only if unlucky, but probably the frame is then the problem (not concentric, or not circular holes) and any alternative won't probably work either.

Hi
Has anyone information of how the frames are tested? I could find info about testing phase from lightcarbon on the tube, but nothing on carbonda or flybike.

How to be sure the info and pictures we see about lightcarbon aren't from another factory ?
As Zomb1e said, trust what you read here, there's plenty of posts about many brands, and for years.

Enter.

The M0009 is a great simple frame.

Lightbicycle is offering two new rims.
One for XC and one for gravel both at around 250g !

The XC924 and the AR25

Apparently the AR25 has a different layup to make the hooks stronger for 4.8bar/70psi tire pressure and 2.8bar/40psi for the XC924.
Otherwise they look quite the same.

Not sure about their hybrid hook except it looks pretty 
I run 29er hookless 300g rims on my gravel and never lost a tire.

Did you check the FM1036A from Carbonda? It just popped out recently.
There is another post here about it.

Did you check that one ? The cryptically named FM1036A, from Carbonda
