hi-
i'm looking to build up a set of fast 700c road wheels (aero)
that i'll
use every day in fast group rides. i think i'll use aero
bladed spokes
like DT aerolights or sapim cx- ray. i can find hubs with
20/24
drilling (front/rear) but where do i find some aero rims that
are
drilled that way? all i can find are mavic cxp33's with 28
holes. any
suggestions for sources, or other rims to recommend? how about
non-proprietary paired spoke rims? also, any opinions on
bearing drag
for different hubsets? i'm looking at some american classic
hubs.
opinions? how about white industries? thanks for opinions
(trying not to spend $800 for rolf prima vigors)

extra questions: the concept of an aero wheel-is it low spoke
counts/bladed spokes that make the difference, or the deep
rim-or both?
are the rims deep and stiff so you can use less spokes, or is
the deep
rim important in a slipstream/turbulence decreasing effect? or
is the
main effect low spoke number?
why is there no data on wheel efficiency? taking into account
bearing
seal drag, wind efficiency, weight distribution (hub vs rim)
etc. has
anyone taken different wheels and just "rolled them down an
incline"
and tabulated that?

Dear Mr. The Blur,

Putting aside for the moment the prudence of a 20/24 spoke wheel,
one choice is the Velocity Deep V.
http://velocityusa.com/rims/road-rims.php . If I were building a
semi-aero, ultra-light wheel with bladed spokes, however, I would
use an Aerohead OC 28 hole rim for the rear. By the way, there
is plent of data bearing on your questions, which Carl Fogel will
undoubtedly dredge up from the bowels of the internet. -- Jay
