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!
