rear derailleur position in dropouts - slipping wheel!
I did a short ride (~8 mi) this morning to run some errands. A few roads were a bit rough. When I got home, I saw that my rear tire was rubbing the chainstay on the left side. Even though the quick release felt tight, the wheel had somehow slipped.
I noticed that the wheel sits pretty far foward, and I'm wondering if it may sit more snugly in the dropouts if it was further in the recesses. I have an old style derailleur that also sits in the dropout, held there by a nut. Should I move both the RD and wheel back, to avoid the slippage from happening again?
Attached are pics of right and left side: notice how much space there is in the dropouts.
