1) See pic. Is this considered an internal cam skewer? I think it is, but just want to verify it's not an external cam skewer.
2) My rear QR skewer is not smooth upon closing or opening, it's just kinda jerky and not smooth (wheel is seated correctly, no junk in there, etc. - it just isn't a smooth acting lever like the front one). It does tighten up nice and holds the wheel nice and tight, no issues while riding, etc. - just doesn't have that satisfying smooth action when closing or opening, kinda stutters a bit. Anything to be concerned about here?
