the seat tube is thicker cause it's cheaper/easier to make, the geometry is fudged just for the sake of it like with all of these copies

Would you mind sharing the pics and weight of your frame?
It looks quite appealing 

I dont buy my bikes on aliexpress and i've had several warranty issues / goodwill instances when my counterparts did the right thing. I've had 2 or 3 warranty / crash claims with Farsports, i've had velobuild send me their updated C rings free of charge, i've received wheels that were centerlock after ordering 6 bolt and received adaptors free of charge. I've had a derailleur replaced free of charge & received a bunch of freebies.

Long story short, there's more to dealing with chinese counterparts than aliexpress & assuming no warranty coverage. I'm the highest tier on aliexpress and usually (not always) they are helpful. I had a bad experience with Alibaba, they clearly gave no F about me, that was disappointing, but i'm not going to cry about it, after all they were sticking to their T&Cs.
In fact 2 weeks ago i ordered via aliexpress a replacement crank arm for cheap. I shouldn't have paid for it, but this seller is a dick and i'll do my best not to work with them again. Either way it should save my ass for cheap enough.

I guess my point is: build relationships with sellers you learn to trust. It's so much easier than it used to be to have clear discussions with them. Either they speak decent english now, or they use translation software that actually works. It used to be an uphill battle to make yourself understood. Now i feel i can ask very detailed questions and i usually get spot on answers.

Last: the vast majority of people still assume that if it's unbranded and chinese, it's poor quality. I have friends who to this day will not use an unbranded chinese bike out of fear of death. Sadly (?), some of them are actually highly educated people with engineering degrees placing them in the 0.01% of the population. Others are just Luddites. Which ties back to Factfulness, in fact.
Most of this forum exists to navigate issues around oval holes, unfaced brake mount surfaces, out of tolerance interfaces, and structural integrity of parts. Together, usually referred to as QC. Aka, quality... Aka, who to order from to minimize the chances of ordering a dud.

A bad exampe could be Winspace with it's Agile frame, it is already too close to western brands and I can purchase 2nd hand SL7 (non S-works) frames cheaper in JPN.
Like the Agile frame direct from Winspace ends up to be 300.000JPY, while a used SL7 frame is ~250.000JPY. With that pricing it is rather pointless to opt for direct China frames.

mine is arrived, and have the lockring with internali splines
