Yes. Those in Post #2 are Shimano QRs, as is the one I posted above. I was referring to the ENVE QR skewers you posted. They don't appear to have the same sort of mechanism; I guess the cam part is harder to see. I was not intending to be critical.
EDIT: I have titanium skewers on my Airborne; they are very much the "external" cam type, but they work fine.


These skewers have a logo on them... which, fortunately, looks pretty much the same upside down! LoL
