I’m sorry, but they had the bonus of both time and the lack of uci rules…… and came up with…… a slower bike.
Just read the pdf file and you can find it says 47 kmph.

Just saying, it should be stated on the chart. If this was remotely journal-like. The missing axis titles is pretty bad

What do UCI rules have to do with it? The other two bikes are also not UCI legal designs

The point is if you cross extrapolate the data between UCI and less constraints of non-UCI you’d hope to see the potential be pushed on in terms of bicycle performance… and it’s not happening.
Wait, what? This thing is slower than a Canyon (and P5X) unless you’re spending all your time at 10+ deg yaw? Why did they even include that chart?
Giant is a unique microcosm that isn’t aware of how much the rest of the world understands.
The trinity release data showed the bike to be slower than the P5 and Speed Concept but they came up with a messy way to display it to obfuscate that.
I’ve digitised this new data so I can model with it.
Using the IMNZ model with 2021 weather for a 4.15 rider (average yaw 1.8deg)
Canyon 17s faster (8 of aero, 9 of mass)
P5X 96s faster (96 of aero, -16 mass)
So clearly the answer for non-UCI is to get a P5X and strip some weight off. Which Cervelo did with the P3X… Best grab one of those while you still can
However, the Cadex does come into its own if you go a lot slower on a really windy day
IMNZ 2019 conditions for a 6.30 rider gave an average yaw of 8.8deg and thus a 34s advantage for the Cadex over the P5X
Of course, independent testing might show a different outcome.

Only because of that P5X rising positive yaw drag, right? If that’s not accurate, P5X is faster everywhere

Very interesting, but not a lot of us normal mortals rude 4:15. I would be interested to see what happens in your software for more mortal time of an 5hr IM ride.
And I think some bikes test much different with a rider on it then without it. But nevertheless, lets say it is 2 to 3 minutes slower for most normal non-pro mortals and you need to choose between 2 or 3 bikes and you like this one the best. Personally I would the chose the one I just like if I like it much more then the other 2 or 3 
But really interested what your software calculates on a IMNZ 5 hr bike ride on the named bikes.

I’ve taken all the publicly available P5X data and normalised to 100 at zero deg
(P5X) was the P5X release data from Cervelo
Tri Light and Heavy were from the Cervelo P3X release
(KAY) is Kileys shootout
There is a fairly clear trend from all the other testing, Cadex managed to be quite different…

Maybe time to bump up the training…

Note my response to justkeeppedalling - the Cadex data isn’t that believable. Knowing a bit about how they collect their data, I suspect the advantage of the P5X to be somewhat higher than their test results show.
The funny thing here is that the data they have posted doesn’t show what they think it does.
But back to your question, this is what their data shows.
I know you like unique bikes, for me - I’d rather go with a simpler (lower tier) bike - then the speed hit comes with a price and hassle reduction
Referring to base bar adjustment on page 7 of the brochure: Is there an aero penalty having it +40mm vs 0mm? I run things more or less slammed on all my tri bikes which means the base bar is generally very low and uncomfortable if I have to use the base bar (like when climbing and getting out of the saddle). Raising the base bar up even that 40mm would help comfort wise.
US website is up: https://www.cadex-cycling.com/us/tri
.
On the P5X people had been told by Cervelo that the up position was faster, presumably because it put the bar in front of the knees more
You want to have decent separation of basebar and armrests, but if you can do that without slamming the basebar - that may be the fastest as well as more comfortable
Obviously can’t know fastest without testing, but there is no reason not to prioritise comfort

The Cadex bike was used in a UK TT for the first time (I think) at the weekend in the National 100 mile TT. Where Tom Hutchinson took the silver medal in 3:28:04
That is a great position. I know he must put in the time training wise, but I’d love to know how he his able to hold that position for so long. It seems like it would be challenging on the eyes and neck after 90 minutes.
What are the road conditions like where this was done-you have any idea?

Course is here:

Largely single carriageway road, mix of newish and older tarmac surface I think there are a few bits of tar and chip / chip and seal.

I think Tom uses the same position for 12 hour time trials too. Training in the position is a major factor. He also does core work and stretching.
Anyone heard about availability for North America?
Anyone heard about availability for North America?
Bumping this up. Looks like they just started selling them in the UK (in munchkin sizes of XXS, XS, and S) and don’t look to be available anywhere else in the world at the moment.
Anyone heard anything about North American availability?
To answer my own question the word I got from a Cadex rep is that the earliest we’d see North American availability is “maybe†2024. ðŸ™
My frameset has just arrived in the shop (Velocity44 Stirling UK).
Just waiting on the 4 spoke/disc wheels now…
Cheers, Andy
