I get a few input here. I own 2 Flyxii frames.
First, I would try the following to recover the problem: use an Avid CPS hardware. It will somewhat recover the angle, not sure that will be enough though.
Second, I am with CD, I will stay away from Flyxii frames in the future, I lost trust. That being said I have pushed my FR-202 to a new limit last week
I had already used it in a very difficult marathon race (the "Mythic" race, Velovert Festival in the French Alps) with no issue. So last week, I took it DH. OK that was a Green rating, but still it was DH in the French Alps, in Orcières. It behaved beautifully, very smooth riding. All the people around were amazed.
So, I am happy with my Flyxii but if it ever breaks... I'll replace it with a CarbonSpeed (more expensive).
