So I am fairly new to road cycling and have an issue with my rear wheel. I had just replaced the tube in the rear tire and popped it back on the bike only to find that the back tire wobbles. The wobble occurs when you grab a hold of the rear tire and move it from side to side. There have been no adjustments made to the rear tire/rim. It does have a quick release, but I made sure that it was nice and snug a few times. What could the wobble be caused by? How much would it cost to get fixed? thanks for the help, I just want to ride!
If you're lucky, the locknuts won't be completely loose and you can fix it without buying a cone wrench (which I'd advise anyway).
Just get a couple of shifters or whatever, and tighten the locknuts until the spindle has only a tiny rattle. This will disappear when the QR is tightened.
The above technique won't work though if your spindle is the type with a groove or flat along it and keyed washers. If you have this type you can actually do without a cone wrench altogether; just substitute painstaking fiddliness.
