A few months ago, I ran across this old (1995) wind tunnel test for aero wheels: http://www.sportsci.org/traintech/aerowheels/jmn.html#zinn#zinn
I was surprised to see the old Spinergy Rev-X do so well. The Ironman photo of Steve Larson on this Lotus (with Rev-X’s) made me think of this.

Hey Dave
say what you want about the old Rev-X but i ran my fastest 40K TT on a set! i kind of wish i had keep my set.
Dan…
I’m with you on this one. I, for years have felt that my 2001 Rev-X super stiff wheels were faster than my Hed H3’s. My fastest combo has been the Rev-X up front with a Renn disc.
I was just surprised that the wind tunnel data backed this up since many on this forum have bashed this wheel’s aerodynamics (not to metion it durability) for years.

What works for you (and the rest of your setup) can vary significantly depending on the other equipment involved. The Spinergy by itself however, is not faster than an H3.
Chris
Perhaps it is not faster than the Hed H3 in the wind tunnel, however, per this article is was faster than the Zipp tri-spoke.

I’m not talking about the wind tunnel, I am talking about real world testing with an SRM.

That would be interesting to see. Different front wheels tested on an indoor track, being measured by a SRM power meter. BTW, I love HED products and plan to buy a new C2 Jet 90 to go with my HED aerobars.

indoor track would only get you data for 0 yaw, or very nearly 0 yaw, where most wheels do pretty similarly anyway.
an outdoor circle track someplace where wind is of relatively constant intensity could get you some good data if you swapped back and forth a few times.
This would effectively give you a sweep of various yaw angles averaged out
