Basically, it's a great starter bike, and a more than ample trainer.

But I want to get another bike "on another level" that I can grow into as far as competition worthiness.

But, if I did decide to upgrade, what would you suggest first??? Changing the 105's out to DuraAce? New wheels? This is where my "newbiness" shines through.

Thanks for your reply though. I definitely need some direction as far as this is concerned, and my local bike shop (naturally) is pushing me towards the 5.2....of course, they want to make a sale, I'm sure.
