I think the P5 will win. But I really like the Zipp!

Maybe I should throw my Ventus on the old Zipp and knock the dust off of it :D
My guess is the 3001 is a bit behind the P5.

My guess too. It will be close, but the P5 will be slightly ahead.

Should be very interesting...
On a side note, seeing that you are looking at older frames do you have any info on this old giant.
It’s a garage build which I didn’t spend any “new” money on.
Ignore the seat, it slipped and I use a dash not that one.
Edit: disregard, giant mcr2 but can’t post pics on phone.
Cheers,
Maurice

Sadly, they aren't that close - bare or with a rider on board.
Not because beams are inherently less aero, but because none of the most recent beam designs have taken things far enough.
Softride Rocket TT - Beam is round on it's front face.
Zipp - Downtube is just HUGE, and the area behind the fork crown is complete crap. At the stem is bad/worse on some sizes as well. The beam itself is like a knife though.
Pearson - Downtube is pretty good (though round leading edge), but there are a few custom ones around that take care of some things that needed improvement.
Dimond - Very good, but wide; as a high drag, high lift design, it suffers in low yaw conditions.
P5x - Fast, but...a lot of surface area.
I own or have owned all of these except the P5x, as well as a Shiv Tri, Felt IA, P5, Suplicy Quantum, Trek SC, TriRig Omni etc. The P5 almost always delivers the best drag numbers. The Omni is often very close.
Most days of the week, I'd rather ride the Softride. It's just a better experience.

Historical note:
Chet Kyle and Ed Burke would not allow me to test the Zipp 2001 head to head against the Project 96 GT Superbike.

That's a good anecdote! :D
Here are the numbers from today as well as a weighted average drag. The Zipp headtube is exceptionally narrow which I suspect is why it does so well at 0deg yaw. We really did give the Lotus and the Zipp the best chance of doing well with the component choices!

Considering the age of the Zipp and Lotus frames, it seems like they did pretty well.

thanks for sharing! Interesting.
Cool to see some Lotus and Zipp data public.
Next up... Lotus 108? :D

It would be interesting to see how an p3(with a p5 front fork) or a fully optimised p4 would stand up against the latest "super bikes".

I've never seen a bare frame in a tunnel, but with all the parts and wheels the good ones are ~.06. Frame alone maybe .02 or so?

Wow, that's a lot of nice gear. Did you find the Dimond Marquise to be slower than the P5? I have a P5-3 with Ventus II Ltd bar, Scott Plasma food storage, and dual rear carrier for a bottle and tire kit. I'm considering getting the Marquise because the integrated storage and fast looks, but never considered the width making it a high drag frame.
Re: Zipp 3001 vs. a Cervélo P5 in the wind tunnel [BigBoyND]
[ In reply to ]
Disclaimer: have not tested a Marquise. Mine is an original model with a P5-3 fork and a few other tweaks.
But the design, while refined, remains the same. It's wide and high curvature. Storage is great, and if you could ditch the two rear bottles completely, there could be a win in some windy conditions.
It is faster than a Zipp. The upper beam is well designed. But, there is a lot of material elsewhere that is hard to overcome.

thanks for this!!!
What can we extrapolate from this to compare a Dimond to a P5?
Here are the numbers from today as well as a weighted average drag. The Zipp headtube is exceptionally narrow which I suspect is why it does so well at 0deg yaw. We really did give the Lotus and the Zipp the best chance of doing well with the component choices!

Hello
great study and pictures. Thanks for sharing all the process and results.
I'm a big fan of the P5 and Lotus (don't know the Zipp), happy to see the Lotus tested :-)
A question : no remark on the measured CdA, but the corresponding power mentioned above is including aero power (around 243 or 244 w for the P5 ?) plus around 57 w for rolling resistance and bike friction for all 3 bikes ?

It’s a different frame, I wouldn’t want to suggest how a Dimond would perform until actually tested!
