Let's see what this does for HED's sales now.

I know it's not a tech article and there isn't a protocol presented, but when did that ever stop anyone on BF from buying anything?

Hed 90's Rofl.

Funny they mention testing aero bottles as faster than round ones and hands below the forearms as much slower and what wheel is that again?

Duke of Kent

Yes, but a dude producing in the neighborhood of 480w+ for the duration of that TT got beat by a guy probably putting out ~50w less.

On a "slower" bike...with HEDs (Bonty copy) and a better position.

In most independent tests Zipps are not the best. The Reynolds DV (46) Stratus beat the Zipps hands down. Lighter stronger better hubs. Zipps do however have the best marketing so I guess they do have that going for them.

Using your logic then HED beat Zipp at the ToC and last years TdF. It's the engine at that level not the wheels or the bike. I'm confident that Cancelara would have won the WC on a Felt or Trek, he's just a stud.

Just curious, where are the independent tests you speak of? I'm currently in the market for a set of TT wheels and would be interested in the results.

Were the 46s compared with the 38mm rims (303s) or the 58mm (404s)? I highly doubt the 46s performed better than the 404s. Possibly better than the 303s. But if you were comparing the 46s to the 303s (1106g) than the 303s are lighter (not that the few grams makes a real difference. I'm a little confused bit the apparent contradiction.

I would also consider that at that level of cycling Im sure that EACH RIDER gets wind tunnel time (no?). Therefore, while ZIPP or HED or Cervelo might test and say that hands down is slower or aero bottles are faster or this and that... thats probably in "most cases". You could certainly have someone whose position is laid out in such a way that it actually makes these things MORE aerodynamic.

That is the benefit of individual purpose specific wind tunnel testing. You don't have to worry about the crappy data that we see every day. You just do what they tell you works the best for YOU.

The 46's were compared to the 404's, your doubt goes to prove my comment on how good Zipp has been at marketing their product. The new DV66 is supposed to be a wicked front wheel for TT bikes. I'll do some searching on the tests. I don't have the link on this computer so it might be later this evening before I can post it.

I m not sure the word "slightly" would be a reason to purchase one over the other for me....I like Hed's prices personally....I feel most of my Zipp money would be going to keep Cancelara riding them...I would rather save a little cash....

cslone

The Bontrager carbon wheels are made by HED.

biffstephens

I have always been courious about this....are they made by Hed or were they designed by Hed?

You can barely see the HED at 12 o'clock on the center bikes from wheel here...

Not all of them. Only the deep section versions. Also, the rear disc that Astana is using now is made by Carbonsports with a nice paintjob to cover it.

cslone

Correct, the Aeolus line is what is made by HED. I wasn't clear on that. The rims are made by Bontrager and sent to HED, where they bond the Carbon fairing and build the wheel. The Bonty disc is made the same way in the HED factory(which is not being used by Astana...they're using the Lightweight with a Bonty decal).

I just wish more companies would offer CF rims. That's one plus to Zipps.

jrennie

Not defending Zipps, Pcad can do that and cslone can stand up for the virtue of HED. I dont ride either. Thought it was funny that csc/cervelo tunnel time would produce those resuls and their top TT rider is doing all the slower options.

wannaride

Hardly damming stuff for the Zipps. There is no quantification for "slightly" and it is only at certain yaw angles. At least one sentence makes no sense anyway: A behind-the-seat bottle holder is less aero than any other hydration option. Air flows cleaner through the legs than behind the rider's butt, so a bottle holder is less of a penalty if it is equal with or above the saddle. The statements are absolutely contradictory.

Just thought you should know about a reply from Josh @ Zipp on slowtwitch:

"For the record, the 808 is faster with a 21mm tire by about 5 grams average and the stinger is faster with 23mm tire by about 6 grams average, but the 808 does it with ~12% less side force for better handling across all angles...not to mention the 808 is about 1/2lb lighter for the pair."

El Diablo Rojo

The companies offering quality carbon wheels are many. What company that you'd buy from doesn't offer a carbon wheel?

cslone

Yeah, because Zipp would admit their direct competitor is faster? Also, HED seems to claim they're wheel is faster, who do you believe?

And this came from Cervelo, who is generally a Zipp riding bike. What would they gain by saying the HED is faster?

Psydotek

Makes sense to me?

They're saying that a water bottle behind the saddle is not as aerodynamic as most peole think. However, if you must have one back there, the higher the bottle the better.

I have been hearing that once CSC's contract is up with Zipp that they will be moving onto Hed's. Has anyone else heard this/read about it?

53x12

+1 I would have too agree with this. The Zipp marketing machine is quite good at what it does. I would also be interested in those tests once you get a chance to locate them.

waterrockets 

No, I mean loose hoops with no innards

It would be cool to see Reynolds and Hed rims through QBP. I like to roll my own, you know?

itri-45

I have zero vested interest in either Zipp or Hed. I thought you and others would like to know how Zipp responded to the statement from Inside Tri. I knew tire size matters (aerodynamically) but didn't know it would cause who wins and who loses.
