Quoting Giant’s website:
If necessary, you may use an inner tube on a Giant hookless rim, so long as the tire you are using has passed the Giant test protocol. However, please note that Giant hookless rims are designed to perform best when set up as tubeless and used without an inner tube.
Nothing related, but I found it interesting that Giant has a list of tires that failed the test, and the Vittoria Corsa and GP5K (old version) have failed.
With hooked rims you can use anything you want with a tube.
With hookless…you really do need a tubeless tire.
I’m clearly not one who believes hookless rims are a problem…but even I wouldnt try a clincher tire on a hookless rim. They’re not designed to be as tight fitting as tubeless, so the likelyhood they’d lift the bead past the edge of the rim am blow off is WAY higher.
According to Zipp, you must use tubeless tire compatible with their rim even if you want to use a tube. That frankly sounds like a road side flat change nightmare.
Even though I love road tubeless, I can easily see that it is not for everyone nor every bike as it requires a certain amount of regular maintenance.
Ah fancy that, three big brands who would be destroyed if they were found out to be covering up a safety issue, weren’t lying after all
I’m not seeing how those photos are proving it was an impact.
Smooth as glass road in UAE and De Gendt hit some giant rim breaking piece of debris in the road that no other rider hit or tried to avoid before hand…
I take it you’ve been to the road in question and inspected it for damage and debris? 
The article shows how the wheel damage is visible in the original photo at the site of the crash. It does not say what caused it but an impact is the most plausible cause.
Or the rim gets damaged in the crash.
Is it possible a tire blowing off could crack a rim? My guess is no but there has to be a pretty large pressure release when that happens.
Rim could be damaged after the tyre blew… but if De Gendt says he hit something I see no reason to doubt him
yes.
ENVE pointed that out years ago, and made a pressure relief valve stem nut.
Don’t want to mislead, but FWIW in 2020, Enve replaced my front wheel as it had cracked near the valve stem:
Both sides. That was before the pressure relief nut was introduced, or shortly after. I’ve got pics from earlier in the year where there was no problem.
Not sure if that was from sudden pressure loss, or something else.
ENVE as always was great and replaced immediately upon receipt of pics.
I was saying, that isn’t a case of hookless/hooked. I don’t understand the noise made against hookless from people openly saying that they won’t use it.
You are surprised that people are discussing genuine concerns re: the safety of the concept with certain tire / rim combinations?
I didn’t, and couldn’t, say who is or isn’t allow to talk about something. I said I don’t understand.
Everyone is entitled and welcomed to have and share their opinion.
My opinion, for instance, is that I don’t understand. Does that mean that I don’t want that someone express their opinion? Not at all!
My point since the beginning is that people are attributing an incident that doesn’t look like a hookless/hooked issued as it was.
A safety discussion is always welcomed. What I don’t understand is the rush to blame hookless and then spark an argument baseless.
But, again, that’s only my thought and I’m sharing it. That’s all. If I was unhappy with my words before, sorry. I didn’t mean.
I personally won’t use it because it has been shown to be less safe than hooked for road use.
This was already posted a couple times up thread but I’ll post it again here.
You must be aware you posted a link where in the description a person says they like hookless right?
This discussion far outdates the most recent incidents…
You must be aware that the same description also indicates that Josh Poertner doesn’t like it presently and the actual article makes several pointed criticisms of hookless, right?
Point. Counter-point.
