So much hookless talk this week, understandably so… a few things: 1) ISO standards are being ignored. 2) 72.5psi (road) is a limit not a target 3) It’s not just 1 failure 4) Rim type+size should be the primary factor in tyre choice, then tyre width. escapecollective.com/thomas-de-gend…
Tyre manufacturer Vittoria insists recent Thomas De Gendt crash "is unrelated to the hookless rim design" despite heavy criticism

After Thomas De Gendt crashed out of the UAE Tour last week, CPA boss Adam Hansen publically criticised the use of hookless rims. Now, tyre manufacturer, Vittoria has hit back.
"If you look at the images of Thomas de Gendt's bike, you see that his tire came off, the safety foam on the inside got stuck in the fork and the front wheel locked up," said Hansen to Velo after De Gendt's crash. There are many people who want to ban this in the peloton, because you can literally take down other riders. One day there will be a massive crash."
In a responding statement, Vittoria has pleaded the innocence of the design, citing a variety of other reasons for the crash. "In the aftermath of Thomas De Gendt's crash during the UAE Tour last week, there has been some discussion about the hookless system. It is crucial to clarify that the rim's failure resulted from an impact with an object, in this case, a rock, and is unrelated to the hookless rim design,” reads the statement. “The intensity of the impact caused the rim/wheel to break in a manner that prevented the tyre from staying securely in place. The force was so severe that it tore apart the tyre insert."
“It's important to emphasise that the accident was not a result of any compatibility issues among the components utilised by the team. The Vittoria Corsa PRO 28mm TLR underwent extensive testing on various hookless commercial wheels, including Zipp models (such as 353NSW),” concludes the statement. “The compatibility was thoroughly validated through laboratory tests, outdoor field tests, and races, with official communication provided through the SRAM website. As members of ETRTO, we consistently develop our products in strict adherence to ETRTO norms, encompassing both current ETRTO standards and "Previous Standard Data (PSD)."

- A bit much to suggest that Pogacar is better than MvdP on most terrains. The only terrain Pogacar is clearly better is long climbs, on any other terrain they are pretty even except flat cobbles and short and steep climbs (max a few 100 mtrs) where MvdP is clearly better than Pogacar.Velovibes21-12-2024

- That’s the most stupid thing I’ve read for a long time, did you not go to school and learn even the most basic physics? Aero depends on one thing only, drag, drag depends speed and the relationship is squared and apart from maybe at zero or the speed of sound or due to side winds that relationship is valid at all speeds, it dies not “suddenly” start at a magic number. Very simply, the faster you go the more the effect becomes important. If you think 25km/h is needed to have noticeable effects you’re delusional, athletic WR are cancelled as soon as winds top 2m/s that’s 7.2km/h, why because the assistance is already too important at that speed and the times prove it. You don’t even consider wind which can significantly increase the effective speed for aerodynamics and you underestimate speed of climbs, 6% is ridden more at 30 than 25km/h, a speed at which early generation high rims were considered to have more advantages than disadvantages. And finally, as in normal races you can’t just switch bikes according to terrain, it’s pretty pointless to discuss climbs as a separate situation, the aero will have justified itself plenty during the rest of the ride.Mistermaumau21-12-2024
