A shot in the dark here but it never hurts to ask, right? I have a Trek 7.3 FX that's about 6 weeks old. It probably has less than 250 miles on it. Last week it started ticking only while I'm cranking. It's a single tick per rotation of the crank and at first it seemed to do it when the crank was in the same position but now it seems to be moving around. I'm guessing it's either the chain or front derailleur, any thoughts? I checked for sticky links by running the chain backwards but it seemed fine.
