Forum newbie here looking for feedback on a bike in consideration: Specialized Roubaix Dual/Triple Comp

Im not a real serious rider (35miles a weekday - 50+ weekends) overall average of 18 MPH on an aluminum Trek 1400. Centuries and fun rides - no time trials, no sprinting, etc.

Comfort and durability are my issues. I want the frame to last another 10 years of regular riding. Titanium prices scare me. The super light aluminum (foil) bikes just wont survive the garage tools occasionally falling against it.

Specialized Roubaix Dual/Triple Comp - DuraAce/Ultregra/18-27, Ksyrium, Carbon, etc ...

Any feedback available from those who own(ed)?
