There are so many Frame manufacturers in the far East and most of them manufacture frames for someone else. They will be made for the original "Named" manufacturer to theit design and Materials. The relationship will be good with quality control at a high degree.
Unfortunately- There are a few unscrupulous Frame manufacturers about that will either make a copy of the original- or will sell the "Rejects" from quality control on.
Not knowing whether this is a well made frame- or whether it has just been made as a copy at poor quality- I would not like to buy unless I could see one.
