Your dealer already has a relationship with ENVE and will probably get a new set of wheels shipped to them without getting the old/damaged ones back, but you don't have that relationship. You, being an individual, will probably have to send the wheels back before they ship a new one out and they just want to see pictures of the problem probably just to verify it actually is a problem.
This. I don't see what the problem is here. It takes a few seconds to take photos and send them to Enve.
