I tried turning the barrel adjustor and that seemed to help a lot until I got on the trainer and put some tension on the tire. The front derailleur doesn't want to shift to the larger cogs at all. Then I dropped the chain. I'm guessing it's still me not really knowing what I'm doing plus the cables being stretched, plus maybe a derailleur adjustement. But I'm hesitant to do anything more to my bike than I already have. It seems like an easy fix, I kinda feel embarassed about the whole thing now.
