Speaking of AX Lightness, $511.50 (380 Euro) for the Phoenix saddle and $529 (393 Euro) for the Daedalus Seatpost.

So we have as of right now:
$3,600 Cranks
$16,000 Wheels
$1,883 Brakes/Pads
$12,500 Frame (if we're doing the TT thing)
$1,149 RD (I like going with individual parts rather than the Super Record groupset, it will be more expensive this way)
$449 Bottle cages
$299 Shifter cables
$511 Saddle
$529 Seatpost

So that's $36,920 without shifters or FD.

Anybody know of any tires that cost more than Dugast?

EDIT: So far I've got $440 for a pair of 700x25 Dugast Touring tires.
