Hello. I wonder how the new Fulcrum Speed 25s would rank in this ranking..."Sister" Campagnolo Bora Ultra WTO line look like a good option considering the data on the 45...curious about the 60s (deeper rim, higher stiffness?) and the 33s then (wider inner rim, higher stiffness?)...am I asking too much??? 

I just realized the tire limitation the Cadex have for the hookless version, it's a bit of a mess to understand what is tested as not working and what is not approved but so far you are not suppose to use the GP5K S TR on the 50 Ultra "as per Continental's specifications on rim inner width, the Continental GP5000 S TR in size 700x25C is only apt for use on the CADEX 42 and CADEX 42 Disc' (could this be legacy of old etrto specs?). The Corsa are also out but at least you can use the Cups... Now always difficult to see what is cover-my-ass and what is really not suppose to be used.

I'm sorry if I've missed it in the thread, but what is the basis of the aero watts numbers? Are they tour test numbers, but with a bunch of wheels into a standardised frame?
I ask because the numbers are of the right order of magnitude to be that - but differences between wheelsets seem lower than the differences they've had in the past when they swap out wheels between control wheels (404s) and whatever-comes-with-the-bike wheels. So I'm wandering what's up.
I realise the magzine iteself does a poor job of this - so the informatiom may not exist - but it would be handy to have a model year for the wheels, since many manufacturers re-release stuff with the same name and different performance.

So on paper considering all factors and notwithstanding the hookless stuff, the Cadex seems like a great performer all around given it’s up there in weight, aero, stiffness and rim design? Hub seems solidly engineered too.

Except it is hookless and the ride is rough...comparing to Lightweight and Bikeahead composite
Yes, except that they're hookless and the price absolutely isn't on the friendly side either.
Edit: heh, I see hookless already mentioned before me

Technically i can see that with hookless construction and wide int width, it demands quite low tire pressure so that might offset some of the rough vibration by design?
Hookless, price both are definitely big concerns. I have just came off testing the Black Inc Five (five spokes wheels) which is 1318g a pair and i can see the immediate benefit of a very stiff design on modern rim bed (wide enough to not bee too harsh) and the stiffness it provides is nothing like other spoked wheels these past generations. The sure-footedness is out of this world when cornering at speed as well as on fast descent.
It’s only 30mm rim depth but with toroidal spoke shapes. The whoosh whoosh sound it makes is fun!
Really want to try the cadex if not for the limb-selling price.

I would be curious to see them tested. Historically those types of constructions are not super stiff (if we except the track specific "Io" that are quite another type of beast), Specialized Tri-spokes, Corima 4 Spokes (or more recent 3 spokes), Pro or Cadex... Having the "blades" or "sticks" so narrow, put them under a lot of flexion rather than tension (there are no "brace angle"), then more complicate to make the sturcutre stiff.
Now compared to other similar wheels, they do not seem to have go the full-aero route, then my interest in terms of behavior.

@C36 thank you for starting this thread and compiling the data. For me the decision comes down to three options and I will ignore the drag numbers because they are all so close. At 188cm / 85kg with a solid sprint, I think the rear wheel stiffness is likely the most important spec, followed by weight. Tires will be 25C Conti or Michelin clinchers.
Wheel model / aero drag / stability (lower is better) / F-R stiffness (higher is better) / wheelset weight
DT Swiss ARC1100 62 / 216.1W / 6. / 54-49 / 1698g
>>Stiffest rear wheel but heaviest overall
Shimano Dura Ace C60 / 216.3W / 6. / 55-46 / 1638g
>>Decent rear stiffness, average weight and nice old school cup/cone bearings
Bontrager RSL 62 / 216.4W / 4. / 55-44 / 1538g
>>Lowest rear stiffness and lowest weight
Any feedback on other pros or cons I have overlooked?

Subjectively, Shimano wheels just roll nice. Is it the cup/cone bearings? Hard to say, but they just work. Objectively, the Bontragers are quite a bit lighter, have effectively the same aero drag, supposedly the most stable, and are only slightly less stiff when compared to the Shimano and DT Swiss options.RedRacer wrote: ↑Sun Feb 19, 2023 10:53 pm@C36 thank you for starting this thread and compiling the data.

The matte finish with the shimmering Dura Ace logos look ace too
comparing tour mag drag number vs giant's own testing protocol.
https://www.cadex-cycling.com/global/te ... ultra-disc
so even giant admits the diff is so small less than 1.5 watt . tires make a larger difference.

According to the Tour article Newmen are going to be importing/distributing the carbon spokes used by Giant, Hunt etc. into Europe under the brand name Vonoa.
Given you can't buy any aftermarket hubs that take carbon spoke, I can't really see the play here. But maybe build it and they will come.
I have a pair of these which use the same spokes.
