So yesterday inspired by the user jakub and his pictures of the build I decided to buy the frame too. I placed my order yesterday.

I could not decide between two frames; this and TanTan FM599, but TanTan frame had the weird RD routing(on the right side) and did not come with switchable dropouts, and I was not feeling like buying new wheels yet. After talking with both sellers, the OG Evkin seller was much more helpful and ready to answer the questions.

I will update the post as it goes from shipping up to the build and then get as many specifications of the frame as possible and post it here for everyone in the future as a reference.

So far,

Communication with the seller:
Contacted the seller a week ago as two different sellers were selling the frame with names; OG Evkin Store, and OG Evkin Official store. I have contacted the official store and asked them what the difference is, the seller answered promptly that there is no difference, but also provided several coupons, so I naturally purchased from them.
Communication so far has been excellent. Seller, unlike many other sellers in AliExpress, communicates in excellent and understandable English.
There was one issue that the branded frame in my size was not in stock. However, the seller was kind enough to send me the frame in yet unbranded state.

Update 1: Shipping
I have asked the seller to ship within china to a courier service, so I won't have to wait much for the frame to arrive in my country(I live in Armenia), the seller agreed and the shipping took only one day, up from the moment of sending to receiving it.

P.S. The frame in question
