My Ciocc is Columbus SLX. I weighed it yesterday and it's under 20 lbs. I have a Fuji track wheel on the back, a Mavic MA40/record wheel on the front, record crank, aluminum bars, aluminum stem, campy veloce brakes front and rear.
I can't tell you what to do to your bike, but that's the setup I have.
