The thing just won't stop clamping on the left, sort of like it is off balance. So... I made an appointment for a tune up in two weeks, first available at the LBS. I figured they would adjust it at that time and if it is worse than that I'm happy to pay to have it taken care of. Darn, I'll be forced to ride my new road bike while this one awaits the mechanic.

Maybe I'll have learning opportunities in the future

Thanks for the suggestions.
