First of all, thanks to everyone for your input. I've been busy (and sick) lately and haven't had much time to spend riding or working on the bike. One more day until my day off.

I actually did take the bike back to the shop (for a different reason, but also asked him to check the shifting), after my first test ride. He made some small adjustments and apparently didn't see any problems before returning it to me. However, I didn't point out the specific problem I was having because, at the moment, I didn't recognize the specific problem and realize I was going to have a problem that was going to be sporadic. To complicate things, I am an American living in Japan with only limited skills of the language. I am increasing both my skills in Japanese and bicycle mechanics through this process but... that is another thread.

1) It is a new bike, but I have close to 300 miles on it now. Would that amount of time on the road fully stress the cable system? If not, how do I "hold the derailleur and force shift it" without bending the hanger? I understand the principle, I'm just unsure how to safely perform the act.

2) The hanger doesn't look bent, but I am not an expert. It's certainly doesn't fit the extreme description found on Sheldon Brown's website. I am still looking for symptoms of a 'slightly' bent hanger. If the hanger is bent, is it better to replace it or attempt to straighten the old one?

3) I'm still trying to think of what "OP" means, sorry. Excuse my 'noobness' to this forum. I'll read the adjustment instructions from Park Tool and get back to you.

4) Still working on 1 through 3.

Thanks. I appreciate your help.
