Rear wheel slipping out of dropouts

Hi all, been struggling with this issue for a while now.

Basically, if I put too much torque down on my road bike, the rear wheel slips out of the dropouts & I come to a stop. Sucks as it happens when I'm usually mashing up a hill. It's already resulted in needing one wheel rebuilt, & I've put my fancy wheels back on so I don't really want it happening again if I can help it.

The way I see it is that there's basically two parts to this. The QR & the frame.

Previously I've used some lightweight titanium QRs, but those kept slipping, I'm currently using a Tacx skewer as that's QR in the flat with the grippiest end bits & it's an enclosed cam one (which Sheldon Brown says gives more of a grip). A few friends have recommended some Hope skewers, which I'll probably try next. I can't see them being much more effective though if I'm honest. All of which I've tightened so tight I've been almost unable to reopen, yet they still slip.

With regard to the frame, I've made sure that the dropout is as clean & free of grease as possible. The dropout is very smooth, is it supposed to be like that? Seems like it'd be hard for a QR to get much purchase on it. It does seem to me that it's not ideally angled though, which seems odd for a frame made by Paul Donohue with obviously a lot of talent (Reynolds 853 with an unusual shaped top-tube though, which suggests that it's a limited run). I don't know a huge about frame building, but a frame builder (Woodrups) is just down the road from me, is it something they could help resolve?

Anyway, I'm a bit stuck really. I love this bike, & as a climber I love mashing it up hills, but with this issue I can never feel entirely comfortable doing that. Anyone got any ideas?

Those Hope skewers are open cam, so will be even worse than the Tacx.

Campag and Shimano make the most secure QR, so try one of those: after a quick rummage, I've got a Shimano QR I can post for a tenner.

Yeah, I suspected that that may be the case. I don't think either of the friends which suggested them have the same frame issues. I'm interested! Any chance you could PM me a photo of it?

Ta-da!

Shimano are great for sure. Pair for £10 here

135mm rear OLD.

Is the axel protruding past the dropout? Even a tiny amount will cause this. If so a washer will fix it.

My friend is going to lend me some instead, of what looks like the exact same type. Cheers for the offer though!

NP.

Fingers crossed...

I've had a look at this, & no, doesn't appear to be the case. Something I didn't consider though, so thanks for the suggestion!

Now just for some nice weather so I'm inspired to ride this bike again.

Well, there's only one way to find out...

Did forty five hilly miles on this last Saturday, over Wessenden Head & then reverse Holme Moss. Both relatively sedate gradients of ~15%. Didn't mash either of them, but the Shimano QR held the wheel in fine without needing to put it on super tight. Gainied a bit of confidence back.

Awesome. Been having same issue so I know what I'll try next. Thanks for posting about it afterwards
