Hi guys
Got an irritating problem. My back wheel under heavy torque keeps slipping out of the droputs. I have checked axle length and all that stuff and am using Ultegra QRs so should be ok. I think the problem lies in the horizontal droputs which are chromed and don't offer and form of resisitance. Anyone have this problem?
I have read a bit on the web and there seems to be a few answers.
Star washers between axle and frame, or tugnuts (whatever they are?)
Another idea was to sandpaper the dropouts a bit to roughen them up.

Anyone tried any of these? Or could recommend me some ultra strong QRs!

Maybe check the dropouts are parallel. Might also do up the QR more tightly.

I've not had a problem with slipping on chromed dropouts.

Skewer is super tight, will check the dropouts are parallel now... :)

There is a solution...eschew all forms of exercise and fill your free time with the consumtion of large quantities of pizza and Guiness. Couple this with a comfy sofa and Sky sports and the resultant weakened musculature will be unable to loosen the wheel / axle. Hope this helps :)

Get rid of teh Shimano and replace it with Campagnolo and your worries will disappear.

Im note sure if they are available still, but I have on one of my Corsas a sort of grippy metal washer/spacer. This has a rough serrated surface on booth sides and seems to work, I had a similar problem with the rear Q/R set up. That coupled with a good tight and correctly set up Q/R skewer seemed to do the trick, my drop outs on the rear of this bike were not chrome plated though.

I dont think changing the rear mech will help at all as the Shimano stuff is top notch. I have both manufacturers ares on my bikes and found them no trouble - except for the one I described above which uses a Campagnolo Nuovo from the early 1970s.
