I have an Oval Master which has horizonal dropouts. When I take off from a stop or torque the bike to hard the wheel tends to slip in the drop outs and rubs against the left chain stay. I have cleaned the dropout throughly to make sure there is no grease or anything slick on them, and have been tightening my quick release alot tighter than I do on any of my other bikes. This has reduced the occurances quit a bit but not completely. (Well I have had no problems with my ultegra hubbed wheel since cleaning the drop outs, but my VeloMax still slips.) Has any one else experienced this and are there any ideas?
Thanks,
Tom

It might depend on what kind of skewer you are using. Some have a toothed 'part' (I don't know what it's called) that provides the bite on the outside of the dropouts. If this part is a little too smooth, it can slip. Try a different skewer, Shimano and Campy are both very good. What you are looking for is a set of skewers whose 'parts' have aggressive teeth and bite into the dropout on tightening.
I have several bikes with Campy rear dropouts, I use Shimano skewers and have no wheel slippage issues.

Thanks,
I forgot to mention in my first post that was one of the other things I have tried. I started with an American Classic skewer which didn't do the job, so I changed to a new Ultegra skewer which defently helped but didn't completely solve the problem. Even though it only occurs on my Velomax wheels. My Mavic and Shimano hub wheels work fine. I assume that this is because Mavic and Shimano have teeth on the nut that contacts the inside of the drop out while the Velomax are smooth. I may just need to put the Velomax wheels on E-bay and build some new ones. I'm thinking some blue Chris King hubs, Sapim X-ray spokes, Sun Venus rims, and Blue aluminum nipples, except on the rear drive brass there. That would show off the bike pimp I am, and make my Colnago look all the sweeter. SWEET!

Late reply Tom - but your problem is not unique. I have 3 Colnago Ovalmasters and 2 CT-1's. THe Ovals all have rear wheel slippage. The CT1's do not. The problem really is insidious, and I have tried many skewers. Can not keep the rear from slipping thoruhg on hard efforts or standing sprints! Anyone have any ideas? Similar problems?

Your hypothesis is partially correct. Sheldon Brown has an article on it.
Quick Release Skewers The Good Ones and The Bad Ones
We have been fortunate to get a world class bike person in Pittsburgh recently. He was the first person to point this out to me. He took a well know and liked "upscale" skewer and literally twisted it in his hand. My mouth dropped. His skewers of choice are Campy or Dura-Ace. I just bought some older model Dura-Ace for one bike and the clamping force is unreal. They are the heavier all steel ones. They really grip.
Lickton Bike even goes so far as to sell 1966 Chorus Skewers. I'd suspect just like the old D/A they are all steel. Lickton Bike Chorus Skewers
Speedgoat in Pennsylvania carries Record, Chorus, and Dura-Ace. These skewers are not cheap by any means but I bet any of the ones I mentioned if properly installed will solve your problem. Speedgoat Skewers
I say properly installed because I also just bought some XTR skewers which are the same as the Dura-Ace. I learned to read Shimano directions. They are excellent and I tend to learn from them. They were clear to only turn the nut and not the quick release end to tighten them. (I often see people turning both and the quick release end with the lever can be turned more quickly.) The clamping force is unreal. Ice XTR This link has the XTR at about 1/2 price. They are a great deal.
I'd just make sure just to turn the nut end and bring them up to max force carefully. I don't think they will slip if you go with any of the top ones.
Good luck.

It doesn't take much to see that any super light, supposedly weight saving skewers will not perform under the extreme loads exerted from the rear axle.
From my own experience with cycling parts, Campy have always made the best skewers,(after all it was their invention) with great closure feel and strong durable parts, even though they can be a bit heavy.
A lot of the early ones however have smooth contact surfaces for the dropout, so you need to make sure that the wheels you use these model Campy skewers on, have serrated axle nut surfaces. Shimano also have very good units too, and i have not had any problems with their upper range models, although the closure feel cant quite compare to that of Campy.
The top end Mavic skewers are also a good unit as well, and are a bit lighter since they use a plastic lever slipped over a steel lever boss to save weight.
Be advised however to make sure that each side of the wheels contact to the frame area has a serrated surface,since its a common mistake for many people to buy wheelsets and then use their favourite skewers, only to discover later that the wheels axle faces have smooth suface contact surfaces and also their(favourite)skewers as well. The result of this error can be as far ranging from a moved over wheel to a broken rear drop out.

Hey Tscott,
I have an Ovalmaster, which I really like, but am thinking about picking up a CT1 Bstay. What are the ride differences you see in the two bikes.
Thanks for your input
