Thanks, guys. I found out this evening that I can get a fitting at my local bike shop. Same shop I bought the bike from, so I wish I would have done a fitting a year ago. Oh well. I'll go gather that info soon and formulate a plan.

Bianchi10, thanks for the response. I'm glad to see the change made a difference for you. I look forward to getting to the bottom of this, as I've been bitten by the bug for sure.
