I'm jealous that your paint turned out well, I have the exact same color on my FM1002 and let me tell you, paint from Carbonda is a roll of the dice...

What was bad in your painting?

I tried this few years ago on another frame.
Coming from a second hand Cannondale, I was convinced it was the only good fork in the world.
The components to put a lefty on a non Cannondale frame were a bit ugly.
You can't maintain a Lefty yourself, unless you invest in very specific and expensive tools.
Make it maintained by a specialist you may find around you is also very expensive.
And you can't temporarily replace your front wheel easily if you break it on a trip or a race.

I then moved to a SID 100mm on that frame.
And now I'm very happy of the SID Ultimate 120mm on my FM936.

Thanks.  Guess I'll see what the damage is when the time comes.  Build day is gonna be delayed a bit anyway as bike-componentsDE continue to descend from the best bike e-tailer of the 00s and early 10s into the worst bike e-tailer in DE of the 20s ... took them nearly 2 weeks of fuck ups and general SNAFUs to finally dispatch the stuff that I ordered - which was in stock.

It may be just bad luck or a logistic change on their side.
I ordered often from them this year without any issue.
They even sped up the delivery to Belgium, 2 days instead of 3-4.

I'm on a  PC and can't see any videos nor links, just big blank spaces

On a Mac with Firefox all 3! videos are visible

Looks legit. I usually layer my AliEx payments with multiple layers of protection and so far all my orders have worked out fine.

Interesting! Do you mind to elaborate on this?

... I use the top cap with the 4 holes and routed everything externally from there on out...

By any chance. Do you have a picture when mounted?

I prefer rims UST or no hole(but the valve)
It is a bit fiddly to pass the nipples+spoke-bit with a magnet when you build a wheel or replace a spoke.
But after a wheel or two it becomes natural.
There is no tape peeling risk when changing a tire, no leaks, easy to clean.
I didn't make a weight difference: more carbon(because no hole) vs holes+tape.

And here finally my report on the two builds based on this frame.

First the frame quality. As you can see in the pictures.
The finish is so so... But ok, it is a relatively cheap frame.

The top and bottom headset cups were, how to say that... kind of rough?
And a quick look inside show wrinkles and carbon sheets going out everywhere.
Glad everything is closed now, so it does not exist anymore 

Then comes a funny thing about the brakes.
This is XT brakes, quite standard.
At the rear, there is a fillet between the seatstay and chainstay that prevents the caliper to move outward as it should to avoid disc rub.
File the carbon fillet was probably not a good idea, so... yeah... file the caliper 
When asked, Tideace confirmed me this was the... solution 
And since we are at it, face the mounts maybe be necessary...

And finally the crank. It is BB92, which in itself is a bad news, but ok.
The frame is apparently designed for the Shimano's wide chainline of 56.5mm. Is this for DH ?
Thanks Tideace for not advertising it as such !

With a normal XT crankset, or SRAM a 32T ring will touch the chainstay...
So I did put a 2.5mm shim on the drive side to push the ring a bit outward.
The chainring clearance is bad but i got a 52.5/53mm chainline which is not ideal but ok.
I asked them some clarifications about this, but got you know... the typical non-answers, so classical when us indelicate occidental folks try to know why things do not work as we expect.
I may ignore an important thing about the Shimano 56.5mm chainline, but I can't understand how a 12sp cassette would work correctly with such chainline.

The FM-009 was a very nice frame, I'm less impressed by this one unfortunately.
