P5x is much heavier, and the course is quite hilly. He also ran shallower wheels compared to normal deep front and disc wheel.

Anthony Costes also opted out of using a disc wheel, and I would classify him as one of the most aero obsessed pros out there.

Make sense but not very good from a marketing perspective if one of your few sponsored athletes won't ride your premium bike for a IM.

I don't see it as bad marketing. A certain bike or wheel choice is better in a certain scenario. No bike will be the best at everything.

Diamondback athletes also choose the Serios over the Andean for very hilly courses.

as an interesting point, last year he biked almost 5min faster with the P5x vrs this year with the P5.

What we don't know is if power output was similar and also if there were any differences in the conditions wind/weather/etc.

Referring back to the ST piece - Triathlon Bikes in the age of Aero - we can speculate that there is no way the difference in the frame account for 5 minutes. Really we are splitting hairs on the frame. The bike course was actually fast according to trirating than 2017. FVL is getting old + FVL was at the front of the bike for the entire 2017 race versus being overtaken by Cam Wurf in 2018.

yep, what most captured my attention, is that one could think that as a heavier bike, P5x would be significant slower in a hilly course like IM France.

that doesn't seem to be the case based on comparison to last year, however that's without knowing the full details and data.

Fred, and all our athletes can choose whichever model they feel will be fastest for them on any given race course. Not much different than road teams using the S or R series depending on the course profile. Fred wanted a lighter bike for the hilly course so went with the P5.

Here I fixed the marketing slogan.


The P5X, the fastest, most technologically advanced triathlon bike ever made, kind of. *See hilly course disclaimer.

No doubt you're right
But I also find it funny when people compare frames in the wind tunnel only
-Road feel
-responsiveness
-sponginess standing
-handling in corners
-handeling while braking
- drink bottle placement options
-fit
-comfort
-matches rider style

Of course there's a million race factors like having a injury or not keeping food down....

Great to see you coming on here and setting the record straight Jake!

That's a luxury stable..."hmm shall I take out the hurcan or the murcelago today?"

Have you seen the course profile?

That should answer your question.

The year I watched some pros rode Road bikes with clip ons instead of thier tt

Doesn't surprise me. There's little that's flat, or 'straight downhill'.

I rode it on my tt bike, but then my road bike is crap, if I had a super fast aero bike I doubt my tt would have been faster.

Fred was the "first" to bring a TT bike in Nice for his first victory there in 2011. At the time not riding a road bike on this course was an heresy for most...

His time was slower this year because we were a group of 5 athletes and nobody could escape which lead to a very controlled pace.

For my part, I rode a Cervélo P5 during the race mostly because all my mileage was done on this bike for the past 5 years hence I know by heart how it reacts which is a big advantage on a technical course like Nice. The lighter weight is also good to take but on a rainy day I would have chosen the P5X for the disc brake efficiency in wet downhills.

Congrats on a great race! Love seeing pros doing some of these "tougher" courses as well. Is Kona your next full?

Terrible Tuesday’s Triathlon

Thank you! Yes, Kona will be my next full. I will first take 2 easy weeks, then will include 70.3 Vichy and 70.3 Nice as "tests" without tapering during my Kona training block.

Edvald Boassen Haagen just won the Norway Nat Champs on a P3, mechanical.

From an aerodynamic perspective, the P5 is one the top bikes on the market. In fact, the only bike that is better is the P5X.

Cool to have a proper pro observation

You look really fast! No surprise you won so much already

Anyone know what the actual weight different is between the 2 bikes?

Weiss rode diamondback serious intead of usual undean at IM Austira last weekend

speaking of which, I would have loved to have had disc brakes on those long descents, but it was raining the year I did it. Guess in dry conditions it's not technical enough of a course for that to make a huge difference.
