The frames look great overall. The only thing that looks somewhat off is the fork on the aero frame. The XMCS aero frame seems to be doing something like the Quick Pro ER:ONE or the BMC Teammachine R. The angle on the sharp, ridge-like part of the fork on the two mentioned frames are parallel to the ground, whereas on the XMCS aero frame, the sharp, ridge-like area seems to be angled upward. Unless my eyes are playing tricks, I guess this is intentional or perhaps an overlooked aspect? Not an aero engineer. Just my observation.
