in the last few weeks the same question has been asked several times, have look and reply to the previous threads if unclear.

You can get quotes from Leon Hu and Peter from carbon speed, you can find both on this forum using the search.
You can also email farsports.
I think all 3, just to name 3 OEMs, will be able to quote for what you're after.
Nothing wrong with light carbon either.
Wheels are extremely commoditised. U shape T800 is going to be U shape T800.

And for good reason, I might add. If you're looking for max bang for the buck, I found that Schwalbe's Ones (a tad more durable) and Pro Ones (super fast but fragile) are often cheaper than Conti and Vittoria and are still on par with the best. Pricing might depend on your country and distributor, though. Same goes for the Tufo Calibra Plus. That's one hell of a fast and light tire, but a bit fragile. I'm based in Germany, so German tire brands are cheap here and so is Tufo, being a Czech brand (which is actually made in Czech Republic in contrast to all the others who are actually producing in the Far East).

The conti gp5000 is made in Asia? The compound is so special and pricing so high, I always assumed it was made in Europe, if not Germany?

Update. On 18 May, the 3rd er9 RD died, and i contacted my reseller. 24 May, i contacted my reseller about my own er9 RD, because there are clear issues with recharging. Long story short, charging it, more often than not, results in the battery actually discharging. Go figure. I have a standalone lithium battery charger so i'm now using that until i get a replacement. I know a thing or 2 about lithium batteries, and i tried several different batteries (the actual Ltwoo battery compartment) as well as several different sets of lithium batteries, in various states of charge: the problem isn't coming the lithium batteries.
May 30th, still no resolution on either of them. my reseller makes it sound like ltwoo is being difficult this time around (for the previous 2, they were more straightforward).

The previous 2 broken ones (contacted my reseller on 17 Apr), i still havent received (it's not entirely ltwoo's fault, because they're in a box with a new wheel, so that took time too, but still, that box has been in transit for almost 20 days now, and i still have no idea where it is. So 1.5 months and still no replacement.

My friend whose RD died on May 18th had a triathlon the following weekend. He's back on his older sworks di2, at least the er9 died on a casual training ride and not on race day...

We're all loving Chinese groupsets in my cycling group, and the behaviour of ltwoo makes it extra tasty.

Aliexpress is still full of Dogma F and Grevil clones, though. It seems there’s a particularly high quantity of Pinarello clones from many different sources. I often wonder why? Is it just desirability and that they’re selling well? Or does Pinarello maybe not pay the necessary license fees for exclusivity or chooses to have that license expire at some point and the factory sells off the molds to third parties? Because it seems that everyone and their mother in China has a mold lying around for the Dogma F12 and the Dogma F. 

I suspect the same reason why Rolex is the most copied watch brand. Pinarello shapes are both highly desirable and recognizable. The brand was bought by LVMH years ago. They know their branding/marketing, that's literally how they make their money. Vuitton bags the most copied, LVMH brand. Seems fitting that Pinarello would be the most copied bike brand too

shouldn't the microspacers be added between the c-ring and the headset/bearing cover (and not the top cap)?
I did try to use microspacers, but in my case, my compression ring is U-shaped and I did not find any U-shaped microspacers, so I ordered regular round microspacers which I cut so they would fit the U-shaped compression ring. I was not satisfied with the result however. The idea that the microspacers could shift and touch/damage my brake hose in the steering tube made me abandon this option.

i 3d printed mine, so they would make full contact with the C ring, and the C ring has a positive notch, so my spacers have a hole to fit that notch. That way, maximum contact area, and can't move to interfere with hoses. In your photo, the diameter of the shims looks very small, and indeed, if you don't round the area you cut, you can expect them to potentially grind into the hoses.

Yes. They're only selling off leftover stock. No explanation as to why.

Feels like everyone on this forum on a 218 had a cracked frame at the seatpost area. Given VB margins, they can't be profitable selling models that are constantly creating warranty problems.
Plus the fact it's an obvious clone of Pinarello, which I assume has resulted in Pinarello contacting VB, one way or the other (and/or the factory they source from).
