vs this:
My first generation Enve CX fork looks like the fork in the second image. I never have had an ejection event, but when I had external cam Salsa boutique QR skewers, I had to re-seat the wheel after every ride, or I would have disc brake rub, indicating a small amount of movement. Upon replacing these with Dura Ace (admittedly overkill) internal cam skewers, the problem went away.
The newer version of the Enve CX fork is through-axle.
