What is the most aero location for a bottle for a 40k TT?
Profile aerobottle on aerobars Round bottle on down tube Behind the saddle on low sitting “wing” cage Low profile thin aero bottle on frame
I am leaning towards the Profile aerobottle to minimize changing my positon.
Thanks for the feedback
From my rudimentry knowledge of this, I am guessing it’s #4.
How hot will it be for the 40k TT? Will you even need that much water?
Thanks
It will be hot and humid, and I am a sweat a lot. The TT will be in Puerto Rico, and I like to have my water…
How about a small camelbak, with tube right at your mouth. No need to become un-aero for fluids. Short of this, I would go with the aerobottle on the bars.

Indeed. You will need water.
Best of luck.

And that would be the first one I’d eliminate from the list based on things I’ve read recently. It may depend on the bike you’re riding, but I’ve read where folks like Cervelo put a lot of thought into the design of that head tube and how it breaks the air and using the profile bottle really screws up that airflow. Plus, that big straw is more of a drag than you might suspect.
I’m thinking about trying #5 this year. That’s the Vision style of system where you use a standard bottle that lays on your aerobars. http://www.amazon.com/VisionTech-Aero-Carbon-Drinking-System/dp/B000LCB48O
Fabian Cancellara uses #2. How bad can it be?
I’ve used the Arundle thin aero bottle on the frame. In the heat of battle, it’s pretty tough to get in and out of the holder without really breaking rhythm and flow.
.
4 if it’s on the top tube. Probably.
Perhaps someone can answer some questions I’ve been thinking about:
Well you have to consider style points as well. I’m pretty sure I’ve never seen a handlebar mounted aerobottle at a TT (well very few anyway) and rarely do you see behind the seat holders. If you’re going to race a cycling race, you have to show up looking like a cyclist, not a triathlete 
I’m obviously kidding, but I’d still lean toward a single bottle on the frame, Psycologist’s suggestion, or maybe even the good old camelback under the jersey option.
4 on the top tube?
Have you seen the rear monted tear drop shaped hydration systems with a straw routed to the bars? That seems to fit your question
1) Why do behind the saddle bottle cages hold bottles vertical, surely they’d be better if they were held horizontal?
We’ve got a couple of triathletes who show up for our weekly group rides with behind-the-seat cages that hold bottles nearly horizontally. We call them bottle launchers.

Ok, round bottle on the frame it is. I the heat of the battle I can always throw it away and feel heroic (will have to go back to pick it up afterwards though) I will look like a cyclist 
And I won’t poke my eye accidentaly with the straw of the Profile aero bottle…
thanks
One option you forgot; down the back of the jersey/skinsuit/whatever you triathletes wear!
Cheap, easy, sorted!
Someone did make an airfoil shaped one, but I cannot agree more. Companies would do allot of good for themselves if they would think about things like this as part of an integrated system, versus bolt-on components. I envision a water carrier similar to that of the fiberglass fairing sport bikes (motorcycles) use on the rear seat, when nobody is sitting there.
I went for option #5 at a triathlon this last weekend, but didn’t actually even use a water bottle holder. I just put the bottle there, electrical taped it in place lightly to keep it from bouncing out in transition/mounting, and then dumped the bottle when I was done with it. Very handy and something I’ll definitely be doing in the future.
if you get caught throwing the bottle away you risk getting penalised.

I haven’t purchased the Visiontech bottle holder that’s designed for use on the bars. I just figured from looking at mine that if I took a very large rubber band and stretched it around the bars, I could easily slip the bottom of a bottle into the space between where the band crosses the top of the bars and where it crosses the bottom. That would seem to be very simple, secure and the bottle would be pretty much hidden from the wind behind my hands. I keep meaning to test it out, but I haven’t gotten around to it.

Oh, yeah, I tossed it just before an aid station at a legal spot.
It’s called a ‘never reach’ and it’s hideous.
I think 4 zip ties and a bottle cage would be another simple alternative to accomplish the same thing… For me it would fit neatly between my aero bar extensions… I gotta go try that out.
I just did, 3 zip ties and an old bottle cage, fits perfect between my aero bars. Riding bike on the trainer now and seems stable. hasn’t fallen off yet
