Chain Help
Hi everyone, I don't know a lot about tinkering with my bike but I'm trying to learn. I took my back wheel off to practice getting it off an on again, I watched a video that said to align the chain on the smallest chainrings when taking it on and off so I did that but now it rubs like crazy on the bottom of a part of the derailleur and I don't know how to fix it. Once I shift it into 4th in the rear it stops rubbing, thanks a lot for any help. Apparently I can't post a picture or even a link to one yet, but I'll add it shortly.
