I'm looking at getting a new frame, specifically a 2013 Cannondale CAAD10 (52cm). Right now I ride a 2009 Felt Z80 (51cm).

I'm just wondering if this would be a pretty smooth upgrade. I love the ride of my Z80, I ride pretty fast on it, have taken it through a few duathlons, but am looking into the CAAD10 because I want a lighter frame that would be faster for racing (20-30mi), and still be ok for a good low/mid mileage weekend ride (30mi). If this would do a century without sending stitches through my back, that's definitely something on my radar too.
I had a 2006 Felt F5C 50cm (

And yes I'm only referring to the 52cm CAAD10 because I've got the chance to buy that frame off someone for CHEAP.
