Cannondale CAAD7 Optimo => Tests,Weight ?

my plan is to buy a new roadracer bike. my old one is aged. in spite of my old bike
is build with an advanced frametechnology (filled brazing processing aso.) so my choice
is maybe a Cannondale R1000 (CAAD7, optimo Frame). but i never find Testdata or Weigth.
Maybe just buy and ride.
