Yes, they are external cam. And there's not really much "cam" to them. Very subtle. Very little "over center" feel to the lever travel. But, at any rate, it's not the lever side that's the problem. The levers are staying in the closed position and are staying in the same orientation as when I close them. Even the very loose front skewer was still closed with the handle pointing at 3 o'clock when I checked it.
[I'm not sure where the idea came in that these are horizontal dropouts. They're not. Is there even such thing as horizontal FRONT dropouts?]
