A few weights
First the frameset. Specialized claims "just under 1000g", but make no mention of size. This is a 58cm and this weight includes the derailleur hanger as well as all of the cable guides and tape that will come out so take maybe 35g total off of this.
The 350mm S-Works seatpost......sold separately
Finally, the fork with the race installed and enough excess steerer tube to use as a periscope if I could come up with a few mirrors.
