That "graph" is a marketing tool Cervelo is using to sell their P4 design, no more, no less.

Go over to ST and read the ongoing multiple page discussion on the true aero gains of the P4.  It is inetersting stuff.

Huh?  That "graph" (or the data behind it) has been on Cervelo's website for years.  It's an illustrative explanation of aero benefits in general, not of one of their products in particular.

You beat me to it-

correct; the "graphs" went up, I believe, right around the time the P3C was released. Look at it again - it has nothing to do with comparing bike models, but uses known aero benefits to determine real-world effects of bike aerodynamics and sped and time.

Are you talking about Cervelo's comparison chart, stacking several other bikes (except the more-aero Trek TTX) up against the P4?

Ahhhh.  Yeah, I'm thinking that was part of the P4 chart.  My bad .......

Right, but who goes out there and says, "I'm going to bike this in 48 minutes" and adjusts their effort level for that?  We go out and put out a certain level of effort that we feel is appropriate, and the speed/time takes care of itself.

I do.  I don't say I want XX:XX time, but I know the pack I want to be in and will adjust my effort as needed.  If I want to be in the first pack off the bike and I'm in the 2nd pack coming out of the water, that aero equipment helps me go faster at that hard effort.  Once I catch the 1st pack and all I have to do is sit 3 bike lengths behind them until T2, that aero equipment allows me to use less watts and still stay with them.

Yes, but you're a freak.

x2!

No Derek, you are correct. A triathlon, especially long course for AG'ers is a race against the clock and as such should be executed at the maximum effort which can be held for the duration of the event. It's a nice fantasy to pretend to be pro's jockeying for position, but at the end of the day it's you against the clock. If you are adjusting pace to go faster either you don't know your pace or you are going to have a bad run.

 I'd be interested to see if someone has or could put together a performance matrix based on "seconds cut per dollar spent" for example ( i just made up these numbers)- if I pick up an aero helmet ($150) and save 15 seconds over an olympic ride I basically purchased each second at a cost of $10 each. Now If I was to add a set of Zipp 909's for $2,000 and save X time then my cost per second is 2000/x. This can be expanded to every piece of gear you could think of.

One of the tritalk podcasts had an a discussion just on this topic.  I think he rated 10 items based on which where the best time saves for the cost.   I think the aero helmet came out top rated, or close.
