I need a black dog flat! looks so nice…
It’s about time! But I’d rather they focus on designing awesome products at a great price than marketing the crap out of their stuff any day. I’m a big fan of Hed stuff.
well, since someone has to point it out, I may as well do so: why are the numbers so different on the website than were posted on this thread here, specifically, this chart:

Forgetting about the raw numbers, the basic curves aren’t even the same for the Stinger 6 and 9 (particularly the Stinger 6)? I don’t doubt that they’re both fast wheels, but it definitely raises some questions–questions I’ve probably want answered before I plunked down my cold, hard cash…
Not sure if they have old charts up still or not. The Stinger 60 and Stinger 90 have both been redesigned for 2009, and they are both cosiderably faster in most conditions. I can assure you, these guys have been designing, tunnel testing, and real-life riding the hell out of the new wheels for 2009.

Linky no worky…404 not found.

I checked the Zipp site, to compare tests
The 808 and 404 curves look similar, not exactly the same numbers, but folow a similar trend

The charts are very similar for all of the data points, except the Stinger numbers, as you pointed out. That is very interesting; perhaps they did some redesign work since then? Otherwise, it will need some explaining.
When looking at the new website data, my takeaways are…
-
Why spring for the H3D…it isnt really any better than the H3
-
The H3 is still pretty good across highly variable wind with no stall and can be purchased used for a few hundred (a good value for the performance)
-
In similar fashion, in variable winds the discs still work consistently well with no stall (I wish they had a flat disc like a Renn or even the older Hed for comparison)
-
Unless you go really deep, most of the gains are small in comparison (get a 1080 or Stinger 9) - either pick all arounder road race type wheels that are controllable in variable wind gusts or really deep TT wheels and just deal with it
That is a sweet website, and some sweet wheels.
Dear Santa, a set of Jet C2 9 FR please for christmas!
Kind of curious why Chrissie Wellington is not listed under their “Atheletes” section. Saw her in a couple ads for HED in Triathlete magazine. With her switching coaches, rides, etc, is she making a switch on wheels as well?
Awesome site, very user friendly and a ton of info.
The plots on the HED website are inconsistent check out the curves for the Stinger 9. One from the Aero section and the other from the wheel section:
Aero:
Wheel:
It could be that for the comparison chart they removed the tare drag in order to compare “apples to apples”, but added it in for the wheel data, but that doesn’t explain the flat part of the curve in the aero section between 12.5 and 15.
It also makes be wonder if they used a Zipp 808 Clincher for the comparision ( because the lines compare very well to the Jet 9) and a 1080 tubular ( because the lines compare to a stinger 9).
looks like the aero section has the old data and the wheel section has the new data
or, the wheel section has bogus data, haha

Yeah…I saw that too (now that the link works again)…same thing for the Stinger 6 I believe. It looks like the data in the “aero” section matches that chart that jason had posted a LONG time ago, but the individual wheel charts are different…hmmmm…
They have done some changes on the Stinger 6 and 9 rims from the first tests from my understanding.
According to the website, the Sub 9 is no better than a 808 rear wheel:
Where is the negative drag of the Zipp Sub-9?
So aerodynamically speaking, the Jet C2 90 is somewhere between the STD Jet 90 and the Stinger 90?

strange way of interpreting that graph thar =)

Any idea on the cost of the Black Dog flat?

Interesting that the Y axis starts at 0 on one and 30 on the other.
Beyond that, the nearly vertical climb in drag from 12.5 to 15 degrees is certainly different. I guess when they say they optimized to 12.5 they weren’t kidding.
Hey, wait a second, no questioning HEDs data, you guys do not do that with ZIPP or Cervelo, you take theirs as gospel, so why start with HED…
