I'm not sure what the point is, exactly. Are you trying to test me on all
possible bike parts, looking for me to say some part is 'not dumb', so you
can say "gotcha! that part IS dumb!" ? Do you sincerely want me to design
your build list for you because you want to build a 19 pound Roadeo and
don't know how to do it? Do you suspect I'm wrong and you want to prove
that I can't build a 19 pound Roadeo? Or are we just killing time because
it's Winter?
Whatever it is, you are right that I have better things to do than to
design a proper and complete build list in the way I normally approach
builds. I approach builds with a lot of forethought and deliberation, and
I've gotten pretty good at it. I'm not going to design a Roadeo build for
you, but I'll give you something in the ballpark.
My 59cm Black Mountain Cycles Road bike weighs 20.2 lbs (9171g) as pictured:
<https://lh3.googleusercontent.com/-xiDzS8dRIe0/WnKLL05wvvI/AAAAAAAADvk/5IhDi47sWgkPgaumF3PRVI5xtkIkMWWUQCLcBGAs/s1600/IMG_0134.jpg>
I categorize everything in five buckets:
A. Frameset (59cm BMC Road + Cane Creek 50 headset)
B. Wheelset (HED rims, 32 spokes, White Industries hubs, Challenge Eroica
tires, SRAM 1070 cassette, standard tubes)
C. Drivetrain (Herse Cranks, White Industries Ti BB, Shimano SPD pedals,
Dura Ace 10 F+R ders, Dura Ace downtube shifters, SRAM 1091 chain)
D. Components (Flite saddle, ultegra seatpost, Nitto Soba handlebars, Civia
Bryant stem, Shimano mid reach brakes, customized tektro brakelevers,
newbaums tape)
E. Accessories (bell, two ti cages)
A 19 pound Roadeo needs to be 545 grams lighter. I assume the Roadeo
frameset is a hair lighter than my $600 Black Mountain frameset, but I
don't know for sure. Assume they are the same. I would save some weight
by running a not-dumb all-metal wheelset. I think carbon wheels are dumb.
Carbon sucks as a braking surface, and carbon clinchers with a metal
braking surface are neither light nor affordable. My current favorite
not-dumb wheelset is the HED Ardennes Plus. Its a 1610g wheelset, with
25mm wide tubeless ready metal rims. Everybody smarts regards those rims
as bomber, and Jenson sells the wheelset for $349. not-dumb-wheels
<http://www.jensonusa.com/HED-Ardennes-Plus-GP-Clincher-Wheelset/> That
would drop about 150 grams. I'd run Chinook Pass EL tires and light tubes,
which would drop another 150 grams. The 220 gram Flite saddle works for
me, but the 145 gram also works for me. A Dura Ace cassette which is
half-ti costs $189 but it saves another 75 grams or so. Don't run a bell,
and a nice steel threadless stem would weigh about 70 grams less than the
one I have. That puts me right at 19 pounds with nothing dumb. I think
that maybe VO Gran Cru brake calipers might be a little lighter than the
Shimanos, but whatever. There are plenty of lighter 'road' pedals, but
whatever. My customized brakelevers might seem dumb. I customized them to
improve the shape and for the fun of the look, but it also reduced the
weight to just under 100g per lever. SRAM carbon levers weigh more like
125 grams per lever, and I could go find 50 grams somewhere else. If the
$2400 Roadeo is in fact a few grams lighter than the $595 Black Mountain,
then I'd be ahead of the game.
