Rear wheel slipping in the dropouts


TrentonMakes

Question

I've been lucky; not much this summer in the way of "mechanicals" but one reared its head on my last ride, and I dealt with it again tonight. 

 

My road bike is built on an 80s-era steel frame with horizontal (forward facing) dropouts (i.e. not track style).  With the tremendous wattage* :D  I pump out while standing on climbs I've pulled the wheel so the tire is rubbing on the left seat stay.  I have a Shimano QR skewer that seems to be as tight as I want to make it. 

 

Is it possible to add a toothed ring washer in there?  Or I suppose I could just go with a bolt-on, allen head skewer (or have the axle swapped out).  Suggestions? 

 

 

...also my rear wheel's gone a little out of true but I can take care of that.

 

 

 

 

* actually I believe it is a lot of wattage, but it's neatly countered by my weight.

Horizontal drop-outs can be a problem. One possibility is that you have an exposed cam skewer. They don't provide as much clamping force. Here's a good article on them:

You could buy some of these:

Thanks, Jerry.  Well, I have an enclosed-cam skewer, but the opposite end is a plastic nut with the aluminum insert and I think that's where the problem is.  I wonder if a stopgap might be to reverse it, so the cam end is on the drivetrain side where it can better resist those forces.

 

As I recall, this issue came up because my rear wheel is built on a Deore LX (MTB) hub that's adjusted for road bike dropouts - the cap nut on the skewer bottomed out before it was tight so I used a nut that the threaded end passes through.  Therefore I would think an enclosed cam road skewer might help.  (the allen head skewers don't seem to have good reviews)

 

But I spent some time adjusting Saturday morning, and it didn't happen on yesterday's ride - although there were a couple times when it felt like it happened.  But no, that dragging on that climb was just me.
