I put them on quite tight and haven't had them slip yet.
I weigh 160, however, I don't have a ton of mileage on them yet (maybe 300-400 miles). I haven't had any brake rub issues with them. I also haven't seen any reports of slippage or rub issues with the skewers from others. I'm sure some other people on here can chime in on that if they have had problems.
Out of curiosity I did a search and all I could find re: slippage was one person who had a problem and then they realized that
they simply weren't tightening it well enough. That I could see, as the shorter length lever probably transmits a less tight "feel" for a given amount of force. That said, even getting them really tight for me is by no means hard. I go by the "just tight enough to leave an imprint in your palm" standard that is recommended by some manufacturers.
These are open / exposed design, and I see nothing low quality about them. The washers in the open cam are also metal, which leaves me to think there is less of a chance for deformation than there would be with the more common plastic washers.
This definitely sounds like a function of your particular frame, which is confirmed in that they work OK on a different bike. To me this sounds like a potential dropout wear issue, which
Lennard Zinn has previous discussed. All you need to do is ride with improperly-tightened QRs for a bit, consequently wear a groove into the dropout face, and then no matter how much you tighten you are going to be out of luck. The closed cam Dura Ace may have had a larger contact area or a different tooth pattern / texture that overcame whatever problems you had. At any rate, something to take a look at the next time you take off your back wheel.
No offense, but Zinn taken out of context does not help. Yes, I have his book, and all the info provided therein can be obtained free on the internet.
It's a steel frame with old-school dropouts. It's very hard to get the drop-out adjuster screws precisely in the right setting, even by using calipers. This is a fact, and even the almighty Zinn agrees, that internal cam skewers provide more leverage than external.
Like I said, KCNC skewers are light but they do have issues with clamping force. Just search this on the net and there are many others like me. I am happy using them on my CF bike as that was the original intent (no point saving weight on my steel ride) but they are made for 1 purpose and that's it.
Actually, I think they look ok too. But that's subjective.
