Looking at the picture, how do I know whether it's a structural crack or just something else? I can see something grey underneath the white paint, but doesn't look like carbon to me...there is a crack in the 'grey' thing. Will HQ Fibre x-ray it for me or do I have to call Cervelo Canada for this service...?
From my experience in taking x-rays of humans, it's by no means an absolute guarantee of locating a crack. because an X-ray picture is two-dimensional, the beams have to pass parallel through the actual plane of fracture. If they pass perpendicular, since x-rays are only an image of material density, it won't appear any different.
Send your frame to whomever you feel most confident will do a good repair, and you'll probably be quite pleased.
