Hello
I think you have to accept some compromises in quality. You should keep in mind that the price isn't comparable to an S-Works SL8. Furthermore, in my opinion, you should have some experience if you're going to take on a project like this—building up an inexpensive frame. Honestly, I think the weight is perfectly fine, and it's not a problem if it's a bit heavier. I think the frame is okay for the money. However, there are definitely some things that need adjusting or improving. That's something to keep in mind.
