I got a DCE XCE29 and a set of carbon wheels from them at the end of June this year. The wheels arrived pretty fast but the frame took a while. I think it showed up on the 5th of September, 5 or 6 weeks after the order was palced.
There was an issue with the seat tube of the frame. The seat post could only be inserted to about 130mm - full insertion length should be 255mm. I sent a note to Ty, never got an answer. There was something sticking out in the tube that would not allow the post to be inserted beyond that depth.
Finally I took a 1" round pine dowel glued some sandpaper on it and sanded down the thing that was sticking out.

Also one of the screws holding on to the cable guide inserts (not sure what is the correct name for those) were cross threaded by the factory and it took an hour to extract from the frame.
The holes on the inserts at the head tube were also too small for the cables to fit through so I had to enlarge them on both sides.

This added to the build time but other than that I'm pretty happy with the purchase.

Would I buy this frame again: no. There are better options out there but I did not know about this forum at the time of the order. My biggest issue with it is the 27.2 seat tube diameter, dropper post choices are limited for that size.
Would I do business with DIYCarbon again: I like the website and I like that the prices are listed and clear - no 'inquire us' BS. So I may...
