Looking at the diffferent build I see that some bolt the derrailleur direct to UDH mount and others have an extender in between that shift the derailleur back a little. What are the benefits of doing so?

I think UDH is SRAM and direct mount (ie the one with the extension) is Shimano ?? Consensus is that Shimano will ultimately move to UDH so it becomes a truely universal standard.

Ah ok, i see

Some better photos of the "final build" - although I'm planning to overhaul the drivetrain a bit - adopting a 38t oval offset chainring and a 11-50 cassette - both in transit.

I also ordered this frame from surprised store and I'm waiting for the delivery. I only get silver screws from them. Where did you get the black ones?

M5 x 10 mm flat head, worked for my frame

thanks! Did you use metal washers for the screws, if so any good source?

You can also get button head titanium screw for about same cost.

I originally switched to black screws and washers but I'm looking to swap them out for rubber plugs/grommets to reduce the chance of rust and also weight savings  . I've tried 4.5mm plugs but they are too small and will need to try out 5mm.

I put these nylon bolts in the unused mount points of my frame. Lightweight, and won't rust. Size M5

I tried Nylon screws for blank threaded holes in a frame years ago.  I left them in the frame for several years.  When I tried to remove them, the Phillips head stripped out.  It turned into a medium mess drilling out the nylon and then tapping the 5mm threads to get the rest of the Nylon out.   I believe that Nylon absorbs water over time and they can swell/lock  into the threads.   I recommend that you remove them on a regular basis and/or use an anti-seize compound.   
These days, I use a dab of silicone RTV to plug holes that aren't used.   (Easily removed and stays in place unless you are using a pressure washer or rub on the RVV while cleaning)

I just bit the bullet and ordered this frame for the 11.11 sale. I went with the Ceccotti RF25 version from the Surprise Store on AliEx. They had the best price, most affordable paint option and the most discounts applied. I almost went with either the BXT 135 and the Flyxii FE-03, but after thinking about it, I wanted something different. Also I might use a semi-internal cable fork with this frame while running the 1x RD and rear brake caliper internally through the frame. I mainly want to utilize the built-in 180mm rotor offset on the EVOSID gravel fork I currently own. Unfortunately it doesn't have the internal cable line.

Today I got my frame, I'm happy with the color (Pantone 9083 C) and the bike itself. But as im an newbie I cannot tell if the paintjob is good/ok/bad.

Especially I would need your advice if I have to clean up some of the threads and if so how to do it best.
So my questions:
- I tested to screw in the bb and that worked so far. But would I have to clean the surrondings of the bb-thread in order not to crack the paint?
- What about the break mount treads?
- and all the other threads like bottle cage holder or bag, etc?
- Should i clean the headset holes and if so, how to do it best?

Additionally i couldn't figure out the following:
- what are the two metal rings for, that came with the headset bearings?
- What is the strange toothshape o-ring for that came with the headset spacers?
- what are the additional parts with the bb for? My Lingmai does not have these?

Thanks in advance!

It's a bit difficult to answer without clear references to items in your pictures, but ill give it a go.

Additionally i couldn't figure out the following:
- what are the two metal rings for, that came with the headset bearings?
* shims i would assume, if you have problems with binding betweend the headset and the frame, add spacers
- What is the strange toothshape o-ring for that came with the headset spacers?
* If you are refering to the smaller object in picture with the scale? that's the wedge that fits beween the upper bearing and the steerer tube.
- what are the additional parts with the bb for? My Lingmai does not have these?
* Shims/spacers once again + reducer and wawy washer for SRAM/GXP stuff?

@hahel thanks for helping me out. And yes you are right i should have put markings on the pictures, my bad.

- I asked the seller also what the washers on the headset bearings where for and like you set, i could use them or not.
- the tooth shaped thing (marked in red) is for using a standard headset and not the supplied one the seller said
- concerning the BB, I will stick to my lingmai it seems to fit.

Where I still need help is cleaning up the paint overspray on the break mounts and the bottom braked rim. Is that necessary, and if so how to do it best? Just use sandpaper and an flat hard object? And should i file the edges of the holes of the headset?

Regarding sanding that's what I did. For the headset, I you refer to what's at the edge of the opening, it's a non contact surface so I didn't do anything to it. If you have paint in the bearing cups, then yes it should be cleaned up
