Shocking blowout of 25mm hookless wheel/tyre combo 

I took the video offline because things got a bit crazy and people were freaking out and making personal attacks, which really isn't worth it for the coffee money that YT pays. Back online now, hopefully people can react more calmly and intelligently. The tyre and wheel have gone off to Continental who are taking it seriously and at this point we still don't know exactly what caused this, but what is clear is that it SHOULD NOT have happened as the wheel / tyre combo is fine / approved, and the pressure was within the max recommended. My personal view is that hookless removes an important safety element for very little tangible gain and I will not be using them in the future, regardless of brand. I have no idea why YT has removed most of the old comments, (including Peak Torque railing against hookless), and kept some others.

Hookless is the biggest gimmick in cycling

But GCN say hookless rims are great, and they’re always so honest and forthright with their opinions aren’t they - right ?? 😉

Great video, I have done countless videos on this subject, I think that there is just too much to go wrong for little to no benefit for the consumer. And only benefit the manufacturers by making it cheaper to make. I will always prefer a hooked rim if I’m buying something.

Scary. I've been running hookless for three years. Followed manufacturers advise on compatible tyres and pressures, and have ridden 34K km with no issues at all. But ... the whole rim /tubeless tyre compatibility issue is a minefield and nobody in the industry seems to want to cooperate. That leaves us having to make judgements we shouldn't need to, and carrying unnecessary risk.

Hookless must go! They are made purely to save wheel companies a small amount of cash, no other reason. I won't touch them with a barge pole. Clinchers and tubes for me thank you very much.

Hookless is the wildest fad the cycling industry tries to shove down our throat every opportunity they get.

💯HOOKLESS is JUST NOT SAFE! PERIOD. 💯

The issue might not be with hookless rims in general. The issue might be with the Extralite hookless rims you have. I went ahead and read the user manual for the Extralite CyberDisk 339 clinchers and there are just too many warnings and confusing information for me to ever consider buying them.

25 mil tire is too small based on the new ETRTO standards. For your rim with it should be 28mm

Putting lives at risk for the sake of saving on tooling cost. Hookless needs to be completely banned by a safety body. WELCOME TO THE BIKE INDUSTRY 🎉

That is insane! So dangerous that! Thank you for sharing this.

This is widely spoke about in the group, what’s to stop this happening… hooked all the way😊👍

i will stick with my clinchers and tubes. thanks for posting this. i have heard about this before but always assumed that people were pumping up with too much pressure.

Thanks for the demonstration. Will stick to clincher, even if I ever go disk! Love that campy set in the background, 2 way fit, no spoke holes, hidden nipples, very nice...

I’ve been riding for well over a year with a hookless zipp 404 with the str with the recommended width of 28mm. No problems. Sorry to see the complications you’re going through, and glad that didn’t happen in the middle of a ride.

Product recall needed!!! This is crazy, thank you for posting

Thank you so much for sharing this! Thank you! I'm so sorry this happened to you, but you're extremely fortunate to experience it off of the bike. Like you said - if that happened on a descent the consequence would be dire.

Hi,

Thanks for sharing, I’m an early adopter consumer, I like trying new tech and went with tubeless on my road bike since the GP 5000 TL where lunched, but this is scary, I would never go hookless after watching this.
