Actually the reasons are stated in the video: increased rider comfort, better cornering grip, better system efficiency, etc. Whether you feel the pros outweigh the cons is a personal decision. For most riders, including myself, the pros of hookless wheels are compelling and the drawbacks either don’t apply to me or are statistically insignificant.

Alex, even taking into consideration who is paying you to publish this, I find your informational video disturbingly lacking of evidence, misguided and even to the point of being potentially high risk. The aerodynamic claims have not been shown. The weight saving of 200g per wheel set for omitting the bead is unproven and I suspect highly exaggerated. The difference in recommended rider weight vs safe pressure between Zipp’s own recommendations and the other unstated manufacturer’s guidelines is highly dubious. The only advantage to hookless is the reduced cost to the manufacturer which isn’t passed on to the consumer. The safety implications of hookless is all that the consumer sees. You and GCN should be feeling highly embarrassed to publish this video.

Most of the ”pros” of hookless seemed so contradictory, this was painful to watch. First mentioning ”better aerodymics” and seamlessly transitioning to ”hookless is best for gravel riding” from there. I thought gravel riding was all about wide tires & low pressures which makes aerodynamics completely secondary? A typical carbon rim at a popular 40-60mm depth usually weighs 400-500 g per rim, so taking 100 g off from the rim’s lip construction is just ludacrous. That example of ”perfectly usable” tire pressures was also quite dubious. I can’t believe how a strict limit of 73 psi and riding pressure of 67-68 psi for a typical middle weight rider and middle tire size can be included in the same equation, as I know for a fact my pumps have about 5 psi worth of measurement error between them. Also, TSS = Tubeless Straight Side, not Sight. I hope GCN could discuss these ”developments” with a straighter sight.

If I have 1, I just ride until it breaks and leaves the thorn in my tire that would have definitely peirced any tube.

Yeah.. go hookless for all the advantages only to not be able to choose a tire that's faster, grippier and lighter. Also there's so many "advantages" listed in this video that are either misinformed or that Zipp didn't really take advantage of. Quick couple examples: - Hookless lighter? I can think of at least 8 brands of wheels of the top off my head that are hooked and lighter. - Hookless drove carbon wheel prices down? No. Carbon wheel prices were going down long before hookless was even mentioned in road biking. Chinese wheel manufacturers who build equal or far better quality wheels than western brands and charging 1/3 the price. That's what drove prices down. All wheels can be dangerous. Hookless is way more dangarous than hooked and it's supported by data at this point. How many more high profile crashes do we wanna watch before we admit that?

I've actually seen a tubeless tire come off a hookless rim mid ride. That rider fell and 3 other people who were on his wheel crashed with him. He ended up with several broken ribs and a broken collarbone. Now, I don't know whether it was user error on setting up the wheels and tires or not but I can tell you I've ridden for 25 years and I've never seen a clincher with tubes or a hooked tubeless do that. At the end of the day, you can blame of the users who setup tires incorrectly but to me, it seems like they've increased the complexity to save 200 grams but added the very real risk of a catastrophic blowout. Do you think I want to ride with the person who buys these things from the manufacturer but lacks the technical acumen to set them up properly and they become a ticking time bomb? It can't be this hard and has to be more reliable and intuitive for the average rider. The cons for the average user outweigh the risk IMO.

After watching this video, I am still not remotely convinced that there is any compelling reason to use hookless rims on any bicycle, much less a road bike. The main advantage seems to be that hookless rims reduce production headaches for wheel manufacturers; for riders, the tiny advantages mentioned here are more than offset by the huge disadvantages. Since I personally prefer to use more-supple clincher tyres with TPU tubes rather than tubeleless, I can't see myself ever switching away from hooked wheels.

Hey ZIPP/SRAM (plus GCN)... please read the room and listen to all the hundreds of comments below (in less than 24 hours no less). For Road Cycling the vast majority of people are not interested in Hookless and see no advantages to them! I'm sorry if you've spent millions changing all of your manufacturing equipment over to Hookless only wheels, but no amount of marketing will convince us that hookless is of any benefit! I've never ran hookless wheels, but I'm sure, on the balance of probabilities, it's a perfectly good system (better for low pressure MTB/Gravel than road IMHO)... if you are careful to ensure everything stays within the correct standards and tolerances. But here's the thing... Me and most people, just want to put any tyre, on any wheel, pump it up to any reasonable pressure than our tiny cyclist-arms can manage 😆and run it in any amount of changing temps (e.g. 15-degs indoors to 35-40 outside in the sunshine!) FWIW: I cycle around 10'000 Km per year. And have ran a lot of tyre brands (Conti, Schwalbe, Vittoria, Michelin, Panaracer, Specialised). In recent years, on my best bike, it's been GP5000 28's (with Latex or TPU tubes, running 73-76 psi @ 82Kg), although I put on 32's on this Winter and I may be sticking with them in future (as they roll REALLY nicely on crappy S.England roads 👍)

The thing is whether you think road tubeless is worth it or not you can't deny that it at the very least offers something over standard clinchers and tubes, depending on various factors and personal priorities it may not be enough to make you want to switch or use it on all bikes, all the time but its there. But road hookless offers what over hooked tubeless? I already have tubeless, I can already run lower pressures, and wider tyres (of which I am not nearly as limited on selection) and I can revert to tubes and standard tyres if I want/need to. You guys have shown multiple times in various videos that decent carbon wheelsets are as tough as nails already and don't need to be "stronger". What does that leave? Highly dubious at best (outright BS at worst) weight savings, wishy washy aero claims, and the promise things might get cheaper in the future? And that's BEFORE we get to potential safety issues.

What I can't get past is the 'limitations' between the hookless rim and the 'approved' hookless tiers for your particular brand of wheel. At least with a hooked rim (tubeless or otherwise) i can use any tire I want without fear of compatibility and/or liability issues. The problem is; there seems to be a severe lack of industry standard because right now, every player in the market wants to be the "industry standard". MAVIC already solved this problem decades ago. Why can't we all just settle on UST?

I do not believe, that we will get arround that corner on a flat tire on a hooked rim either. Or did somebody achieve this masterpiece, already?

sorry but the slight aerodynamic and weight advantages do not make up for the obvious safety downsides. while riding, one must now carry an accurate pressure gauge to not overinflate the tires. can't use a co2 canister anymore because of the overinflation risk. let's also suppose an 80kg rider purchases a hookless rim/tire combo, perhaps during some sales, and then goes online to check the pressures and either finds out different calculators give different values or even finds that the chosen combo is not even approved to work together. this does not feel like progress, except for the 1% who race professionally and have support cars and mechanics at their disposal, not for the average weekend rider

As a big tubeless fan (after finding a proper sealant - milKit/OKO), I am also back to running tubes in the commuter and ordered TPU for my deep sections. Whatever they are pushing, I feel I need to do the opposite now.

I do feel that my video which explains the pros and cons of a system in the hopes of helping people make informed decisions is a helpful one though. If hookless tech isn't for you, that's totally cool. What hookless tech or tubeless tyres have you tried? Yes, hookless is potentially dangerous, when used above the maximal pressure. But isn't that true of any product's maximal limit? What is most important to me is that the industry allows people to continue to make their own choices.
@phil_d

@alexpaton6795 Thanks for your comments, Alex. Firstly, I don't think hookless is a 'technology' as there are too many compromises. To me, it's a manufacturing advantage for the brands. Secondly, I don't agree that the same tyre on a wider internal width needs less pressure. If you measure the tyre when flat, it will have the same overall width, which is then divided into the overall inflated width AND height. If the inflated width increases (i.e., a 28c tyre on a wide rim may measure 30mm) you will lose height. What that means is less height volume increasing the risk of rim strike, even more so if you use less pressure. The actual air volume stays the same. There is also the consideration of dynamic loading spikes. Hit a pot hole and the pressure in the tyre will spike and as in my previous comment bike tyres do not have a stiff/steel sidewall to deal with these, which is why a hook is an integral part of a wheel's design.

Interesting. Had a Specialized Pathfinder Pro 38, literally blow off my Zipp 303s rear rim earlier this fall, while riding down a paved bike path on a warm fall day in Central Illinois. A combination that I had been using for 15 months without incident over various terrain and tire pressure. Since it was a road ride, the tire pressure was at 67 psi... so definitely below the maximum recommended limit of 72.5. Inspection of the rim and tire by my LBS came up with zero explanation as to why that happened. The tire had been in use for approximately a month when this happened. Wheel had been trued a few weeks earlier so it's a mystery as to why it happened and when it did. Fortunately it was a rear wheel, and it happened at a reasonably good time. 😓

Max allowed pressure for 38 mm TL tire on hookless rim are 57.2 psi. Unless the tire blows up wider than 38 mm at given pressure on given rim. If it's actually 40 mm wide max pressure is 54.4 psi. Of course you hade a catastrophic failure, you overinflated your tire/rim combination because it's to complicated to understand the limitations. This is just one of the reasons why hookless rims are a really bad idea.

@@JonRoth_MusicSourceProDJ Equal tension = width × pressure. When you increase tire width you need to decrease pressure for the same tension. Using psi as unit for pressure, and mm as unit for width the max allowed value for tension is: 2175 for hookless/tubless, 2610 for hookless/tubed or hooked/tubeless, and 3045 for hooked/tubed. Changing units to bar and mm the value for max allowed tension are 150, 180 and 210. (since 1 bar = 14.5 psi). Simple math. Easy to remember.

Hookless isn't a technology. It is the lack of a hook. I still don't know "why" they did this. It didn't improve anything. It just made the manufacturing process cheaper for the companies and everything else more complicated for the consumer. Weight savings? He's saying 200 grams per wheelset. That's quite a bit. I say BS. It would be negligible at best. Better aerodynamics? I say BS. The tire should sit against rim the same with or without hooks and would be more dependent on the tires, not the rims. Again, negligible at best. Better comfort? That is all dependent on the size of the tires and tire pressures which can be the same with or without hooks. You can ride really low pressures with hooked wheels too. I call total BS on this one. Hooked tubeless ready clinchers are the best bet to give you the ability to ride both tubes and tubeless, a better variety of tires that are available, and the extra safety measure of a hook to keep your tires secure. I still don't see any advantage for hookless. If anything, it's the other way around.
