For the purposes of avoiding work to be done, I have been daydreaming
about my fantasy road bike that I am going to buy when I find an extra
$10,000 lying around.
Here's the requirements:
under 7kg
able to withstand my 98kg (someday 95?)
comfortable
maintainable by me (ie no bonded kevlar spokes or similar craziness)
deep section clincher wheels (despite weight penalty) due to potential
for multiple flats and need for aero.
Here's what I've come up with:
Pinarello Paris carbon frameset (I have a alu Pinarello and I like the
geometry and handling, but not the weight) 59.5cm
Shimano Dura Ace drivetrain (I want 177.5 or 180 cranks so this limits
my options for lighter cranks) because I like the brifters' shape.
Wipperman stainless chain cuz I ride in the rain and live by the sea
Zero Gravity Ti brakes
Deda Zero100 stem
Deda Newton strada bars
San Marco Regal Ti saddle
Time RXS Ti pedals
(also Rocket 7 shoes. Light shoes don't seem to come in size 50 from
anyplace else)
Zipp 404 clincher wheels
Vittoria Pave tires
This comes to about 6.9kg (a shade over 15lbs)
Any suggestions for alternatives? In particular the wheels might be
improved. Clincher deep section, though.
Huh. I would think that even with that rather light weight budget, most
of the ProTour bikes would work, or would work with minimal fiddling.
There's not really a lot to choose among them: do you like the Scott
CR1, Cervelo Soloist or R3 Carbons, or the funky new Trek 6.9 with the
two-size fork and press-in bearings? Any of them can be built to 7 kg
with a fairly normal parts mix.
Here's an Aluminum Soloist (I'm pretty sure it's Al going by the
slightly less faired-in tube shaping) with no especially goofy parts
(32/36 spoke wheels!) and Campy shifters that comes in below 6900g:

It is a 51 cm frame, though.
As you can see, the absurdolight bikes really get going around the
13-pound mark, when they start specifying aluminum cassette blocks to
drop another 50g versus the lightest Shimano Dura-Ace cassettes.

Here's an almost-boring Litespeed Ghisallo in size ML (compact geometry,
but it looks like it would fit someone near to 6 feet) that sports no
parts more exotic than Dura-Ace, excepting only a dysfunctional-looking
7g water bottle cage.
It's a little less than 6.9 kg.
Note that some of these bike weights can be a tad suspect. Often the
part weights are listed individually, but the more honest builders will
describe whether the assembled bike was weighed as well, thus accounting
for the odd grams here and there that crop up, either due to lubricants,
parts not at mfr-spec weight, or forgotten odds and sods like stem nuts
and bar ends.
