Is there a problem with Hookless? SRAMs relentless IP filing!

[@basedgodstrugglin]

Next SRAM IP filing: A double triangle structure were a wheel can be attached to the back. At the front a structure can be attached (a “fork”) where a second wheel can be attached.

[@SenorGonzo]

Will there be a direction bar attached to the “fork”?

[@alastairstedman7840]

No next sram ip is probably an MTB front mech. The only reason their 1X system ever became a thing in the first place was because sram needed to market their way out of not being able to make a MTB front mech that worked properly.

Being an old fart I left hookless rims (and 1x groupsets!) behind in the 70's and seeing them come back is a bit like the vinyl revival for me. All very nostalgic, but after a few tyres blew off rims back in the day, best left in the past.😀

[@scifi2688]

Tubeless Rims had it's problems back in the 60's/70's. 55-60 psi was the max back then and gluing the tires to the rim was common. Sealant, even today, started to seal when the air pressure dropped down to 35-40 psi. For Mtn applications, it's a tolerant tradeoff. TR hooked Rims should be the standard. Otherwise the Rim walls has be lengthen by a few mm and/or the tire sidewalls stronger and a few mm longer to set deeper in the rim . About 5-7 years ago, people were proposing a return to hookless rims but also requiring machines much like how automobile tires are mounted today. But there's a lot of resistance to losing the ability of tire changing and mounting tires by hand. Also, I'm sure many of you suffered from tires that are imperfect or out of round tires, so Improvement of tire manufacturing has to meet more accurate tolerances.

Been watching out for this promised video! Here are some rough notes I made while watching: 1) the reason you don't see many sram filings in the last couple of years may be due to the 18m period where applications are treated confidentially by the patent offices, The numbers up to end of 2021 will be accurate, anything beyond that is still in the "fog of war", so to speak. 2) you don't need a working prototype to get a patent, but the idea should pass basic muster and be plausible, e.g. you can't patent a perpetuum mobile or something clearly nonsensical. The requirements for something to be plausible depend on the area of tech: much higher bar for medical where you might need to already have results from studies showing efficacy of your active ingredient/preparation, much lower for mechanical engineering 3) it is not strictly advised to take an invention you developed at a company and go away and file for it yourself, because the company may have a case against you if the company can prove that you invented it while on their payroll and that it was an area of tech related to your job 4) patents can take years to be granted, depending on how badly the company wants a broad claim. having a patent pending for a long time can be advantageous because no-one knows how or when it will be granted. 5) the sram carbon rim patent has been granted in the US, CN, TW, but is pending in Europe. The independent claims are also limited in that "each of said plurality of strips extends less than completely around said radially inner portion, said first sidewall, said second sidewall and said radially outer tire engaging portion.", so whether the CN manufacturers may be infringing or not is unclear, for example if their strips extend completely around, that would be a good argument for non-infringement. Sram's priority date goes back to 2018, so to invalidate the patent you'd have to prove that this feature was known before then, either published or in a product or some other kind of disclosure. 6) that sram is willing to enforce their IP should be common knowledge by now, so it makes sense to check out what they've got cooking before developing a product. Campi had to be really careful with their new wireless groupset precisely because they didn't want to tread on sram's shoes.

In 2016, Jaguar Land Rover sued Land Wind for copyright infringement and unfair competition before the Beijing Chaoyang District People's Court.

@@thefunktopuss930 A Chinese manufactured product that infringes a US patent can be legally seized at customs. Whether the agents inspecting it will know that it infringes is a different matter, but the US Patent law does absolutely prevent sale of a product that infringes a US patent. It also protects copyright and for that reason, bootleg DVDs of US copyright movies were also seized, when it was possible. But more to the point, Winspace can absolutely be sued in USA for selling a product that violates a US patent. And they would be careful, because they have money to lose in patent litigation. Once someone sues you, you have to defend yourself.

A friend of mine is a patent lawyer in London. The stuff Amazon is patenting around conveyor belts, for eg, is there 100pc to prevent competition, and not to protect their IP. SRAM here is doing the same. It's sad when a business focuses more on preventing competition with such shitty practices rather than by innovating and making great products. I don't think I'm ever buying anything SRAM ever again. Their 10T cassettes and small chain rings are dumb AF, their groupsets got heavy and ridiculously overpriced, zipp stopped being a category leader over five years ago, out with SRAM, in with competitors.

@charlesmansplaining same here. SRAM are just sellers of snake oil and quite sleazy at that. I remember Sachs front mechs - lightweight, perfect shifting in all conditions - SRAM has bought the company with all their patents and failed to copy what was working flawlessly. Failure after failure, they have actually convinced people that by getting rid of the front mech completely, a rider will benefit both on rear shifting quality and ease of maintenance.

Totally on board with your your appraisal of hookless rims. Always seemed like a problem looking for a solution to me. Hooked rims work for all riding condition. Nice and simple. Couldn't ask for a better design. Hookless rims have too many limitations and require too much careful consideration by the user as to whether they are appropriate to use or not. As you state. Mr. Torque, this is all about money and profits, not customer satisfaction.

Poor Hambini being stuck in the forest today... 👀 On topic: If the whole hookless is meant to be some sort of savings scheme, then why are ENVE and ZIPP still charging up to 4000USD for their wheels. Shimano seems to have nailed the value/performance with their new C-series wheel set, Ultegra C50 can be found for as low as 1200 euros. Why would anyone pay 3500 euros for a pair of ENVE?

Hey Teaque Pork, I tested out Galfer disc brakes after your video on possible resonance with elite wheels and shimano discs. I have found the last iteration of shimano discs (RT800) now produced in china, to be of poor quality and impossible to set up without squeeling. To test out if the squeeling was caused by possible resonance, I switched them with Galfer disc rotors. They have been flawless, even with prolonged braking at 70-80 kph, no squeeling, no brake fade, excellent performance. Check them out, excellen brake rotors.

I did the tyre testing for Kristian's team at Sub7Sub8. We had to use Cadex hookless tubeless wheels because they were the sponsors and it was a launch event for the Cadex Triathlon bike. We knew the wheels themselves performed very well in wind tunnel tests on Giant trinity. We knew that the availability of hookless tubeless specific tyres was going to be an issue and I wanted to know what the wattage delta was to conventional hooked rims. So I tested hooked versus hookless on smooth and rough rollers with the same tyres (the ones which worked on hookless). What I found was that even on a smooth aluminium roller the same tyre run hookless (at the same range of pressures 80-100psi) the power consumption was slightly lower. On a rough roller the difference was magnified. I am guessing it is to do with the hysteresis losses where the bead is constrained by the hook. (all tests run at target pace of 52km/h).

Using hookless rims on narrow road or gravel tires is crazy, even if you use foam inserts.

Motorcycles have a compliant member like that on the rear sprocket but that's more for managing the application of torque and not damping resonance. I wonder if you could just tune the wheel resonance just to push the spoke or rim resonance out of the range of any harmonic that the disc and pads create.

I f*ucking hate hookless. Neither I nor the Trek service manager could mount a 25mm tire on the rim with an inner tube, like they're forcing down this tubeless path, and I'm not doing that shit. I sliced my arm open trying to mount their 25mm SES tire. I had to go up to 28mm tires, which yes, supposedly they're more comfortable, but the fact that the wheels dictated my choice and not my desire for increased comfort makes me angry. I'm still not 100% confident I can fix a pinch flat while on the road.

The "admitting" around 5:45 describes an explanation of a technical problem that can be solved by the invention. The problem might exist just for certain conditions as you have already stated. Hookless rims might be optimized to be more cost efficient as compared to hooked rims. Making rims cheaper to produce AND providing the customer with cheaper rims might not be sooo bad. I do not know if the hookless rims are just viable in case of using disc rotors.

[@mpvsystems9302]

If SRAM wanted to get a lock on something valuable, instead of putting the hooks back on a clincher rim, they should figure out how to mechanically key a tubular tire to a tubular rim. Needless to say, Zipp's tubular rims are obviously less expensive and lighter to manufacture than their clinchers, and this would potentially recover the very minor increase in RR caused by the glue....

[@chrisridesbicycles]

Why so complicated? Wouldn‘t it make more sense to get the old tubular tape out and glue the tire to the hookless rim for things like Roubaix? Good points on the disc squeal, never thought about it like that but maybe MTB wheels squeal a lit less because they are often 2-cross or 3-cross and there is no single resonance frequency.

Legally I'm not sure where you would stand on that and it may depend on what you have in writing and/or your legal jurisdiction. ETRTO also recently updated their minimum tyre width guidelines for wider rims, which puts a few brands at risk now.

Bit of a rant against patents there old chap. Most inventions are pretty simple when it comes down to it and your patent attorney doesn't validate the engineering principles because it isn't necessary, and it's the inventor's job to provide an enabling disclosure. Junk in, junk out. And are inventors really badly treated? Perhaps to an extent, but the reason the employer gets right in the invention (usually) is because they've already paid the inventor to come up with it, by employing them, and will then have to invest even more to take the back of the envelope description you've whinged about and turn it into a product. The reason most countries in the world have a patent system is because it is economically important to be able to protect ideas in order to do business. Also, you haven't considered that the only reason you even know about a lot of the technology described in patents is because they are described in patents. That's the deal, you tell the world and some time later everyone can use it. It is a bit old man shouting at the sea to complain about them.

@@PeakTorque Well you kind of did for the first few minutes. I don't think you really understand patents or how the system works tbh. You are in good company, so don't take this too hard. Consider your comments on the drawbacks of hookless, for example. You think SRAM are somehow acknowledging this in their patent. They aren't, they are trying to build in inventiveness arguments for an overmolded hook, likely so that they can make hooked rims the same mold as their hookless ones. Being able to make something cheaply isn't inventive in most countries, so they need another reason. Making something that works better or has broader usage is an arguable technical advantage though, so the attorney has told this story. I don't know why you think that's not inventive, mind you. Seems quite clever to me. Similarly, I doubt the radiating layup of unidirectional tape in the Zipp patent is anywhere near as broad as you think it is, because you weren't talking about the claims by and large. The priority date could well pre-date the Winspace products or even Hunt's wheels I suppose, in which case I'll look forward to some ill informed article on road.cc or Velo later this year. Post the patent number for the Zipp one and I'd be happy to give my take on that.

@@DrJ-e6z i am named inventor on a number of engineering patents and have worked with numerous IP lawyers in the UK and China. I know how it works thanks though!

[@DrJ-e6z]

@@PeakTorque Ah, well in that case I am en engineer. The Zipp patent in the US explicitly excludes the continuous winding techniques that I believe are used by Winspace et al. This was to overcome JPS61244602A which discloses composite reinforcement of an aluminium extrusion. In the pending case in Europe, the applicant is trying to argue that a continuous winding does not constitute a "strip" and also adds the limitation that adjacent "stacks" of strips must overlap. So if you have a stack that doesn't overlap, or an overlap between continuous windings, this would not fall within the scope of the claims (based on a quick look at the case). I don't think they will get very far with the argument that a "strip" isn't anticipated by a continuous winding, but time will tell... The EP examiner has said that using unidirectional tape is inventive, however. Not sure why, because using unidirectional fibre is an obvious "lying in the road" development in of itself I would say. In China it appears that the originally filed claims sailed through. Hard to judge whether this is because the 1980s Japanese case was not cited (in which case it is foolish in my view to covetously claim in this way) or because the internal definitions are considered by the examiner in China to exclude the prior art. The headline overall is that SRAM/Zipp are trying to protect a rim that has been reinforced around the spoke holes by separate fan like stacks of reinforcement. My best guess, not being an engineer, is that this construction saves weight c.f. continuous windings.
