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?

They're some Dura-Ace C24s I've had for a while, but haven't used in a while. It looks like the clearcoat-y sort of thing over the carbon fibre has flaked off a bit in some places. I don't have anything else carbon other than a few forks & I've never seen that on them. Anyone seen this before & got any idea whether they're safe to run?

Ha, it's been a little niggle for as long as I've had this bike, but never got around to sorting it. Yes please! Bring out on Sunday? I'll remind myself to send you a message.
On a related note, may bring you the original fork at some point to see if you can remove what's left of the steerer extender. I think it'll probably need drilling out, but it's proper hardy metal so none of my drill bits will do it.

The original fork for my Donohue had a steerer extender in it with a rounded bolt head, so couldn't get it out. A friend came around today to try out my bike (he was looking to buy a similar size frame & was curious about fit) & commented on how bad the headset is. Eventually persuaded me to take action & sawed off the end of the steerer extender so I could get the fork out (couldn't unscrew the headset before). Will solve that steerer issue later, in the meantime I've stuck a fork I had lying around (& some other tyres as these clear 28mm!). Feels refreshed! I've got another fork lying around which I eventually want to use (straight blade) but I don't have the courage for cutting/plugging a carbon steerer.

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