You sell Cadex products don’t you? Are you not a Cadex dealer?
What he said. Cadex tests to 115 PSI, but they explicitly say it is not safe to ride above 72.5 PSI. Engineers and architects test their designs at multiples of the safe operating specification to account for defects, tolerances, variances, and error. The testing provides a greater measure of safety confidence at the designed specification. It in no way informs safety in conditions that exceed the design specifications.
You’ll see the disc wheel is not impacted.
“Furthermore, all rims manufactured in DT Swiss`s own facility in Poland are NOT affected by this recall.“

Keep swinging and missing…
Depending on the wheel tire combo you can go up to 125 psi
Currently with the disc and the “aero” tires you can go up to 115psi… in 28mm ( which that would be one awful bumping ride )
Now if you want to talk about the new Cotton Tires those are different.
Different ? What pressure can they be used at ?
Thanks for all the ideas.
I didn’t mean to start another hooked vs hookless debate. I need hooked tires as I want to be able to inflate them to at least 80psi without breaking the manufacturer limits. Pretty black and white.
I know that the DT Swiss recall currently doesn’t include disc wheels, however the scale of the problem is very significant as they are recalling wheels worth a significant chunk of their annual revenue. This is a huge problem which may strain the company’s operations, finances and service reliability.
By the way, this tire isn’t on BRR for 28, but let’s compare the 25 to a Conti 5000TT in 25
CRR = .00459 vs .00252
so (0.00459-.00252) * 85kg * 9.81 * 10 for a 75kg rider at 5h IM speed.( 75+10 = 85kg, 36km/h = 10m/s)
17 watts.
Really ?
The ability to pick tires that are optimal matters
The ability to set optimal pressure matters
Don’t apologize, Eric uses every opportunity he gets to turn this into a hookless discussion [ pink ]
I gave 2 recs that were NOT given. One was a hooked disc and the other wasn’t…
BRR?
You see what that tire reads in your picture, ‘tubeless system’ not ‘hookless system.’
Like any brand Cadex wants to make tires that fit all wheels, hooked or hookless. They are not built for exclusive use on hookless wheels.
Hooked wheels that uses these tires can have higher pressure. That is faster, we have explained you that as often I assumed you understood by now and the tire can handle that, that is what that means, hookless cannot. That why it only reads ‘tubeless system’ and not hookless system on the tire. And the new tires have, hey, look at that, an extra piece of text…hookless compatible.
Somehow you missed the memo that these upper limit values were meant for hooked wheels. I even think there is still a page somewhere on the Cadex site where they explain this and also, because of the hookless limitations that they found, they lowered the min value.
1. Please note that the stated MIN pressure on many current CADEX tires (e.g. 85psi for 25C tire) was originally defined based on a durability test with a 120kg load at 1.5 times the regulated distance. CURRENTLY, for all CADEX tires this minimum (MIN) pressure can now be defined as 70 psi (4.8 bar) for 23C & 25C tires, 50 psi (3.4 bar) for 28C tires and 45 psi (3.1 bar) for 32C tires. Never inflate to less than the MIN pressure.
The decal on the rim, as I was once told by Cadex, is to make sure people don’t go over this pressure to get their tires properly seated.
See how it reads Tire Pressure Recommendations and not Hookless Tire…
Their calculator is still off as they told us it should have an update to the new ETRTO norms, but if you think you can run their disc with their Aero tire in 28 mm in 115 psi thats only for you because they probably made that aero tire for you only in 28 mm. I have never seen one other then 25 mm in their aero tire.
And that is now also not allowed any more due to the inner rim width of 22.4 mm on their disc, yeah, as I said calculator needs to be adjusted as well as their own chart that they display but as they tell all dealers do not exceed ETRTO norms.
Maybe you should become a dealer

Hookless… CADEX Wheel… Max Tire Pressure 125 PSI
CADEX Tire… Max Pressure 125 PSI
And you disagree with me and we can have these conversations like adults… But if you want to treat me like a child and talk down to me or anyone else… You can 100% be shown the door and I dont care who follows you out. It’s unnecessary to treat anyone like that…
Bicycle rolling resistance
I don’t treat you like a child, you started this by more or less mockingly asking if I’m a Cadex dealer and answering with outdated decals. So you get the hand returned. If you can’t handle that, not my problem.
I’m just saying you read it wrong. On a mockingly note, yes. Like you did.
You read it as if you can apply that pressure to a hookless wheel which you can’t, obviously, very big safety hazard, but I’m not going to rewrite the post again.
You are good buddies with Cadex, ask them how they feel about riding their disc at 115 psi. with an aero tire in 25 (as 28mm isn’t available in that tire). It is in the cotton version but that has a 5 bar limit, new tire, updated pressure limits displayed.

Bless your heart
Seems like, at minimum, we all should be able to agree on the fact that the way wheel/tire manufacturers are documenting the limits/requirements of their tubeless wheel “systems” is a complete shit show, and something needs to change. If it’s this difficult for the people on these threads to figure things out, the average consumer doesn’t have a prayer.

Didn’t you mean 120 PSI correct?
