I weigh 175 lbs. and I can put some good torque into my compact double (I'm riding a steel frame). I'm having trouble with my wheel coming out of the dropouts, or becoming misaligned. It's a big problem. Are the wheels to blame? I already took out the dropout adjusters, and tightened the quick releases about as much as humanly possible. What can I do? Wheels are a big investment, I know this because the the wheels are brand new. The axle rests about half way through the drop out. Is this to blame? Maybe the axle isn't long enough? There is knurling on the quick release and on the outside of the hub.
Check the alignment of dropouts, and if QR mates with dropout with full surface on both sides. Maybe you could use marker or some kind of fresh ink, paint the dropout, install everything and then observe if paint transfer was uniform.
If you have spare wheel (or you can borrow one) ideally without QR try installing it and see if problem persists. If the problem persists, than the issue is on the frame side, or in the way you are tightening. Otherwise, it is on the QR side.
Lastly, I have to ask this, are you sure you are installing and tightening QR right way? (finger tighten, and then use lever on QR to get a good tight)
The dropouts look like good quality chromed steel, i.e. quite 'hard'. I realise the QR skewer is brand new, but if it's not great quality the serrated (?) nut faces may not be hard or 'sharp' enough to bite into the chrome. I'd suggest trying a better skewer, or possibly using sharp toothed washers between dropout and nut:
I had a similar problem with my brand-new tri bike. My issue was it had adjustable dropouts so you could snug the tire (depending on tire of size) right up to the frame for maximum aerodynamics. In my situation, the anodize plating on the dropouts was so smooth, as was the carbon finish on the frame, there just wasn't enough friction to keep the dropouts from moving horizontally. We ended up sanding off the plating on the dropouts and putting carbon grit in between the dropouts and frame, which has worked beautifully for two years now, including adjustments for different tires.
Looking at your pictures and assuming you don't have an axel issue, my only suggestions are:
- Make sure dropouts and QR nuts are clean and free of grease. Use some citrus cleaner or equivalent.
- Try roughing up the outsides of dropouts with a low-grit sand paper?
