Let me be one more guy that says "nice bike".
Unless you are doing elite racing there is no reason for you to need to upgrade anything. I know a guy that is a regular Top 10 finisher in P/1/2 races that rides a BD Motobecane. Your bike is WAY nicer than his. It is also way nicer than anything that I own.
So there is no "need" to upgrade or buy a new bike, but if you want to do it more power to you. 99% of the folks on BF have bikes WAY WAY better than they need and that is A-OK.
