I wish there was a dislike button. Who are you, and how much 1st hand experience with VB and other frames do you have?
Saying there is "no quality control whatsoever from velobuild" is simply false. I don't even want to argue, I just wish posts could be downvoted.

I'm sorry that you feel butthurt. It would certainly help the conversation if you could bring yourself to argue your point. Have you audited their production to know they are doing any QC? Are you sure you aren't conflating quality with quality control? In general you don't necessarily need any of the later to produce a decent product...

I've bought two frames from them, one perfect as you can only wish for, the other had a fork steerer tube that was 2mm(!!!) out of round, oval oversized pressfit BB (so you can't press in anything because you can just pull it out without any force), threads of the brake interfaces filled with resin, a seat tube that was only reamed out to about 7cm depth, voids on any machined surface and flaking paint right out of the box (that it wasn't painted as agreed upon should be a given at this point),.
The issues of that second frame are so obvious and present through the whole manufacturing process that I can't imagine even a rudimentary QC process to miss ALL of them and not pull that frame at some point from the production line before it reaches a customer.

I've audited enough production places to know the theme. They aren't evil, notice the defects and send them to the customers anyway - they just don't have dedicated processes set up so a defective product can be detected and pulled from the line at a later stage without incuring penalities to the person reporting the defects.
QC is a significant "non-productive" share of the production cost. If you can cut that, you'll be able to offer the product for cheaper. If your production is set up well in general, so the defect rate is low, you might even come ahead in customer experience on average.

Looking great. Almost done in 1 day... impressive!

You could have used some dampner on the cables to avoid that rubbing sound. Not sure you are a weight weenie ahah Some ppl end up not putting it because of the 30g extra 

As regards indexation I don't think you'll have a major problem with it. Keep us updated and show us the final result on the road too eheh

I would honestly just expect no quality control whatsoever from velobuild.

Most if not all my Chiner (frame) parts had QC stickers on them somewhere. Whether that means that somebody actually checks tolerances or whether there's just some bloke applying them to make customers feel good - I don't know.
Anyway, I've not dealt with Velobuild in the early days - only started buying from them in 2022. But ever since then I have followed the VB threads here closely and they dealt reliably with all warranty claims from what I can tell - even if it takes a while sometimes. And since they do seem to respect their warranty and ship out replacement frames and parts, you would think that they're making some kind of effort at least to not have to deal with overly many of these issues.
Also, Chris told me that all their parts undergo testing according to the ISO 4210 testing protocol. However, providing documentation of ISO 4210 fatigue tests is obligatory if you wanna sell bike parts in most countries, AFAIK. No matter how cheap the stuff is. So that is not really a distinguishing factor.

But on the flipside, you will find plenty of horror stories of bad QC from the big brand's frames. This is the internet. People are very vocal here when they have issues. And very rarely are they screaming about it when stuff just works. Though this forum seems pretty balanced most of the time.

That does not mean the average quality of bikes that are shipped to the customers is bad (especially for the price), it just means there is no established process that consistently checks if what is shipped out meets some kind of internal quality standard or is exactly what the customer ordered.

If the production process is running great at that moment and you aren't looking for anything special, you'll probably get a frame punching way above its price point. If the workers in the factory had a shitty day or were in a crunch to get a batch of frames done before the holidays, you'll get a horrible frame in the mail. They might replace that shitty frame free of charge or completely refuse to do anything at all, again depending mostly on the luck of the day (and to a part your reach in media...).

I tasted the electric and it's really great for the settings which offer a lot of possibilities. Without counting on internal wiring, much easier. It's very difficult  to go back.

Yeap! I completely agree. It's like driving an automatic gears car. Notwithstanding the manual still has its advantages, and at the moment comparing a full 105 hydraulic to a di2 is double the price 500vs1000.

I'll be using an old 105 given by a client in this frame. LC advertises it as allowing 4 cables so I'm not expecting it can't handle mechanical shifting. That screw is adding additional support which is always great, not crucial, but great. Replacing the hanger is a solution, yet let's see. Looking forward for PaxiH feedback
