Speaking of downright forum n00b clown, you only needed to quote BryanD there. If your devoted fanbase wanted the 200 lines of back-and-forth prior to that, they have...the thread.

You said you're going by the charts. I'm saying that's a ridiculous way of supporting your contention as they're inherently biased. If I'm missing something then do tell; always happy to learn.

You are missing the fact I never said the charts were the perfect analysis. I said, and I will say it again, I'm using the charts as a comparison because that's all we have. Please enlighten me where we have other data? Oh that's right, we don't.

Bad data is worse than no data. It causes people to draw incorrect conclusions as opposed to looking for the real answers.

Of course you failed to address the Mullen v. Dowsett power difference which is just as inaccurate as what you've put forward (the difference being I did so in jest).

I'm so terribly not sorry that I didn't schedule that into my day.

Let's do some analysis.

Mullen was on the new Cannondale Disc brake bike and Dowsett was riding a Canyon?

Ryan Mullen https://en.wikipedia.org/wiki/Ryan_Mullen is 6'2 174 pounds. Alex Dowsett is 6'0 and 165 pounds. https://en.wikipedia.org/wiki/Alex_Dowsett

So Ryan is taller and heavier then Dowsett. He did 458W and Dowsett did 441W.

It must be those evil disc brakes. Right....

So how was the weather during their individual efforts? Same wind?

The tires were the same on the bikes right? Same stack and reach? Same frame sizes?

What about clothing? What about their individual Cda? Wait a minute WERE THEY USING LATEX TUBES?

And we can go on and on and on and on and on.

You are looking to blame everything on disc brakes which is a flawed analysis.

Why aren't we testing the P5-X? Well, because we know from Rinard that a round bottle on the downtube of the P5 costs 3-5 watt. We know from Cervelo that the P5-X is only faster by 3 watts, and also that they tested the P5 with a round bottle on the down tube (plus gels on the stem). So, QED: an intelligently configured P5 is faster than a P5-X. This isn't a debate. If you don't put a round bottle on the downtube of your P5, it's faster.

I like how you just passed over this above from PV.

You're funny.

You seem to miss fine details. P5-X was claimed to be 3 Watts faster AVERAGE from -15 to +15. I think you are smart enough to understand what average means.

Another fine detail you missed. Cervelo never claimed to put aero as #1 for this bike. You knew that right? The goal was to make as fast as the P5 minimum, and improve from there. Darn those pesky engineers.

Take the gu's off, the downtube bottles, and the aero pouch and re-test. Then, if it's truly slower, well then we can criticize some more.

EDIT: And I'm sure you will claim "oh but you missed the fine details of all the GU's." Well no I didn't. I posted the pictures to a thread and talked to Cervelo about their test protocol. The sky is not falling where I'm at so I'll just sit back and wait for the white paper to explain their reasoning. However, I'm sure there is a crisis support hotline you can call about the P5-X anger. High blood pressure over bikes is bad you know.

Bryan. Take a step back. Think about what is getting your blood boiling. Reassess.

This is a really fucking stupid conversation.

Now that's hilarious! At the end of the day, I'm not emotionally involved in this. I'm just poking fun at you and One Line Robert.

You know why I like this debate? Because I'm really fascinated by bike frame design and I want to see if bike engineers can truly pull off what they claim.

That's really all it's about for me. If it's slower and they can't cool. If they can, awesome.

Interesting how you can poke holes in my Mullen v. Dowsett comparison yet you shut down when someone does it to a Cervelo graph...

Umm...I told Cervelo I didn't understand parts of their test protocol.

I specifically told them I didn't understand why they taped GUs on the stem, why use an Aero Pouch on the Shiv, and why they put an XLAB Bento Bag between the arms on the Ventum. I was told "wait for the white paper."

You guys think I'm a blind fool! However, that is not the case. I just refuse to accept the doom and gloom sky is falling opinion that most of you have.

But you can't seem to accept that the P5x is slower when you get rid of all the gels?

I don't understand the whole doom and gloom thing you're referring to, I just don't think the P5x, and all disc brake TT bike for that matter, serve any other purpose than a cash grab for manufacturers. Anything that raises my CdA is bad, especially if I have to pay for the 'privilege'.

If it is then that sucks. You have to ask yourself if the tradeoff is worth it for better brakes. I look at it as a starting point for what's to come. I don't know why the rest of you can't see that.

9 pages of it—hey, I did my part—so far.

So, we have another 991 pages to go.

Giddy-up.

'Better' is not only subjective, but also not a primary concern (P4 is still the nuts) in a sport where going as fast as possible is the goal. If it really is a huge concern for some then a P3, Omega X, and Hed Jets will do the same job cheaper and faster.
