I am considering getting a brand new Cervelo P5 but the only dilemma i have is I can decide if I would like the P5 six or the P5 Three. My fit options are much better in the P5 Three vs the P5 Six however aesthetically the P5 Six is much nicer than then P5 Three. After talking with my local Tri Shop the aero dynamic advantage of the P5 Six vs the P5 Three is negligible and there is no wind tunnel data to show that that the P5 Six is faster than the P5 Three. Furthermore the 3t Aduro cockpit configuration is less than ideal with the High V riser (which my fit requires). Either way I am sponsored by my local tri shop so the cost difference does not matter to me.
I ended up with a p5-3 second hand an love it so far. I went with my own cockpit as well and it has allowed me to hit my position much better than the auduro would have. I don’t feel like I am giving up anything to anyone else out there despite the slimmer fork.
Because I see the P5-6 as more “fittable” than “adjustable” and want some scope to possibly make further tweaks to my position, I have the P5-3 on order, which I will most likely pair with USE Tula bars and TriRig Omega brakes. I’m hoping K-Edge will eventually release the TT mount that was mentioned here: http://www.cyclingnews.com/features/interbike-2012-k-edge-unveils-tt-mounts-for-garmin-and-srm
which would put a Garmin between the extensions and in front of the stem with the Tula. And perhaps a TorHans Bento Box to clean up the airflow behind the stem. With all that, I don’t think there will be much aero penalty compared to the Aduro.

Curious what your thoughts are on going with TriRig Omega versus stock Magura Brakes?
To use the Magura brakes I’d need to get the flight pods for the Tula to be able to fit the Magura levers, I just don’t really see the appeal of doing that and using the Magura levers and brakes vs the Tula’s standard aero pods and levers with cabled brakes such as the Omega.
there is a whole thread dedicated to the P5, don’t know if you’ve checked that out but just some thoughts on your points:
your fit - you say the p5-3 would fit better. How so? If you’re going to need to “add stack” then personally the Aduro high V is about as good of a way as you’re going to get to do so.
aerodynamics - the difference gained from the non-uci fork and beard is apparently fairly small; the Aduro is a much bigger gain over the 3T aura apparently
Personally, I’d go P5-3 because the price difference matters and I think it is a much better looking bike. It sounds to me like price doesn’t matter to you and you like the 6 more, maybe there is your answer…
If you are not 1000% sure of the fit, get the Three.
If you are 1000% sure of your fit, I’m sure you can fit on a Six.
I would not concern myself with the speed of the beard and fork, but my understanding is that the bars are more significant. Something like a Ventus is more on par with the Aduro.
But that puts it above the extensions, not between them, so it’s just adding frontal area compared to having the Garmin in front of the stem. The thing that is special about the K-Edge is that they are making it attach by sliding front to back rather than rotating, to allow it to go between the extensions.
Thanks, someone else had also mentioned that to me. Getting something low cost like that from the US is a pain because although I don’t mind paying the taxes when it arrives in the UK, the delivery companies charge an admin fee for collecting the taxes that will be around 50% of the value of the item. Not a huge amount of money but the principle of having to pay considerably more for the admin fee than the actual taxes is really annoying!
Drag: according to Andy Coggan’s home made wind tunnel, the Omega is a wee bit more aero, but both are good. Reality could be a bit different since there is no spinning wheel in his home tunnel setup. You also have to factor in the levers, magura forces you to use a flat brake extension or their levers are no longer aero. Some of the minimalist levers may be more aero than the magura levers. splitting hairs though really.
Braking feel: The omegas are good, a little bit less good than a normal brake once you get it set up well. The Maguras on the other hand really are super-awesome-amazing. If you use carbon braking surfaces a lot, and have the coin, they might be a good idea.
Can’t lose either way really!

The 3T Aduro is really the only huge aero advantage of the Six over the Three. It has the downside of making adjustments in your fit a bit difficult, but there is nothing less than ideal about the high V riser. It adds no drag. Also looks super cool.
If you need a high V with the Six, you will need a stack of spacers with the Three, or a high stack aerobar with the Three, and that will look and perform worse.
You would need a really expensive aerobar on the P5-Three to match the Aduro, like a Ventus or USE Tula

So do you think you would have the ability to brake later with the Maguras and would that offset the slightly less aero profile?
