That's very unfortunate to hear, I guess you're very unlucky. Seems like not all owners run into the same issues like you did. As far on my judgement of the frame, no issues so far. Fingers crossed that I won't run into trouble and need to deal with them once after putting some milage on it. I'm building up the frame as we speak.
Hope everything is fine. I had two issues: Headsetplay (top), after complaining they told me I had the wrong centering ring (don´t know if this is the right word for it). They sent me a new one, but it was exactly the same one.
Second issue was the tight clearance between fork und frame. Adapter they sent me didn´t work and I´ve bought a different bearing, which doesn´t fit lengthwise (49 instead of 49,5mm) but builds a little bit higher.
Can anyone sent a photo of the "centering ring"? I bought a cervelo one, but haven´t tried it yet.
Regards,
Jim
