That's really disappointing, do you think you'll have to try out a different headset/fork? Or will you be able to make it work?
I did my first ride on Thursday around the neighborhood, and other than tightening a few bolts everything worked okay. I need to work on fit some more, my Velofit seemed to put the seat too far down and with my 165mm cranks it just felt like my legs were "compressed" and I couldn't really get much power out. I did notice that if I brake hard, the fork does "chatter" some front/back, but I haven't ever had a disc road bike so that may be normal?
Overall, I really like the Ultegra mechanical groupset, shifting has been reliable and smooth even with the internal cable routing.
Your bike looks great, so at least you have that going for you!
For the fork and integrated handlebars, I have it lined up with only 2 spacers and it looks a little better with some pressure applied. Plan on finishing the build enough this week to ride it a little, hoping the 2 spacers are enough or that I can even remove one for my fit, then I'll cut the fork and brakes lines down and finish it up.
So far I've routed the brake lines and the di2 cables and battery, which was easy. Installed levers, bottom bracket, crank, crankset, brakes, etc. All of that has been easy and quality has been good on those tolerances on the frame. Synced the di2. Just need to throw on the wheelset and bleed the brakes so I can play with the headset spacers.
Cool! I've been following this thread with the greatest interest, as that bike is pretty much all in my Aliexpress cart (airwolf frame, Magene power meter, Elite wheels)
I even put that same saddle on my Triban today
All in all, as of today, would you advise to buy or to look for something else?
Will let you know my report on it soon, but probably would have been happier spending $200 more for something with higher quality.
