Excuse me in advance for the following. I am an inexperienced rider who just got his first "nice" bike and I don't know the terms very well, so hopefully I can explain it.
I just picked up my new Trek 7.2 FX today (they assembled it out of the box for me, so no test rides on it). I took it home and rode it around for a bit. After about ten minutes, I noticed that whenever I shifted into my 2nd gear on my (crankset?) front gears seemed to make a crunching noise as if they were in between gears. If I shift out (to 1st or 3rd) and back into 2nd, it will fix that problem. For this particular issue, maybe I'm shifting incorrectly...I don't know, but after it goes away, then it sounds like the chain is almost rubbing up against something. I looked down and I didn't see it rubbing or anything but it appeared as if the chain wasn't perfectly straight...like a very slight sway to left and right.
Any ideas?
