I own, ride and race the Ican A9.
Very satisfied with the frameset. When I build it up, I was impressed by the manufacturing quality and finish of the frame. It's very stiff and 100% suits the purpose of an aero frame. Though I'm not going to make aerodynamic claims, it feels and rides fast when I'm riding solo. Quick in accelerations and easily maintains its speed.
Oleg might have had issues, but when I look around, each brand has several cases of products that should not have passed their quality control.
