Inside MIPS - Advancing Helmet Safety

If you've gone to purchase a new helmet lately, there's a good chance that you found yourself confronted with a dizzying array of options. All helmets are required to meet certain standards, but more and more companies are working towards developing products that go above and beyond those existing certifications, especially when it comes to reducing the amount of rotational force that reaches the brain during a crash.

MIPS is one of those companies, and although they aren't a helmet manufacturer, 1.7 million helmets were sold last year that were equipped with their low friction layer. I stopped by their headquarters just outside of Stockholm, Sweden, to learn more about the company's history, as well as what the future holds.

MIPS' offices and test lab are housed in a half-circle shaped building just outside of Stockholm, Sweden. They're not the first occupants, so the fact that it resembles a helmet when viewed from above is merely a lucky coincidence.

What Exactly is MIPS?

The term Multi-directional Impact Protection System sure sounds complicated, but the basic premise of MIPS is actually quite simple. It involves placing a low-friction layer (a thin piece of plastic suspended by elastomers) between a rider's head and the helmet's EPS foam. During a crash, this layer is designed allow the outer portion of the helmet to slide over it, reducing the amount of rotational energy that reaches the brain. Why is rotational energy bad? One word: concussions. When you hit the ground at an angle, which is typically the case in a mountain bike crash, your skull stops moving, but your brain, suspended in cerebrospinal fluid, continues to rotate. This rotational motion has been linked to concussions, as well as subdural hematomas and diffuse axonal injuries.

“My hair does the same thing – why do I need MIPS?” That line pops up fairly regularly whenever a review of a MIPS-equipped helmet is posted, and it's a valid question. After all, if you press down on the top of your head and move your hand back and forth your scalp moves – it's easy to see why some riders would be skeptical. According to MIPS, they found that the amount of force that's put on the head during an impact prevents a rider's hair or scalp from doing much to reduce the amount of rotational energy. That's where that plastic slip plane comes in – it's designed to be effective even when subjected to the high forces generated during an impact.

Hons von Holst and Peter Halldin, the originators of the MIPS concept.


MIPS may seem like a new creation, but its beginnings date all the way back to 1995, when Hans von Holst, a brain surgeon with the Karolinska Institute in Stockholm, began working with the Royal Institute of Technology (KTH) to study the biomechanics of head and neck injuries. Petter Halldin, then a PhD student at KTH, teamed up with von Holst, and after several years of research the two of them came up with the original idea for a Multi-directional Impact Protection System in the late 1990s.

The first commercially available helmet with the technology was released for equestrians in 2007, and by 2010, cycling, ski, and motorcycle helmets equipped with MIPS were being produced. It still wasn't all that common in the mountain bike world, but that changed in 2014 when BRG, the parent company of Bell and Giro, invested in MIPS, creating a surge of new helmets that included MIPS. Even though BRG is an investor, other companies are still able to license MIPS, which is why you'll find it in helmets from Scott, Troy Lee Designs, Smith, and others.

MIPS developed their own fixtures in order to measure what happens when a helmet is impacted at an angle, rather than the traditional linear drop test.

MIPS' Test Lab

If you look inside your helmet there's usually a sticker that contains a list of all the certifications it has achieved, whether that's CE, ASTM, CPSC, or SNELL, etc... Unfortunately, there isn't currently any form of certification in place designates whether or not a helmet provides an acceptable level of rotational impact reduction. That should change in the next few years – a team of industry experts has been assembled that's currently hashing out the details of what the certification process will entail.

Despite the fact that there's not currently any rotational impact standard, MIPS have developed custom fixtures in order to do their own research (research that they've also had verified by independent third parties). More than 13,000 tests have been performed in the lab, providing MIPS with a wealth of data to continue to evolve and refine their product. MIPS also use a computer model of the brain in order to simulate the effects of different impact forces and angles, in some cases reconstructing an accident and then comparing CT scans to the computer model to assess its accuracy.

MIPS headquarters
This test involves dropping a helmet at between 6.0-7.5m/s onto a sandpaper-coated, 45-degree anvil.
MIPS headquarters
High-speed cameras capture exactly what happens at the moment of impact, while sensors measure the impact force.

What's Next?

MIPS have several new products on the way, including the MIPS Spherical design featured on the new Bell Super DH. That design involves sandwiching two different densities of foam on top of each other, with a MIPS slip plane in between. It's intended to work like a ball and socket, with the outer layer rotating during a crash, and the inner layer remaining stationary. Eurobike takes place next week, and there will be several more advances unveiled at that time, all designed to help make sure riders' heads are protected as much as possible in the event of a crash.

 So interesting! I'm so excited for the technology that's being developed right now because it means in 5+ years it will be even better and maybe concussions can become a rarity in our sport versus an expected consequence of riding bikes.

I'm continually amazed at how at the surface, things like helmets seem incredibly straightforward, and expensive tech like MIPS looks laughably simplistic to an uneducated eye, but if you do some digging and learn about the how much analysis and data is used to create these "simple" products it gives you such an appreciation for the people working to prevent brain injuries in our sport.

It's a different conversation but IMO replacing a $300 helmet after a crash is expensive but honestly, missing a single work week due to recovering from a concussion is WAY more expensive and shittier. I'm happy to pay more if it means there's less of a chance of longterm consequences.

 Anyone who's suffered a concussion or repeated head trauma will see that current helmet technology needs to be improved. We need better protection. Period! I used my MIPS helmet today to its full potential. Still am feeling a lot of symptoms even with it. I wonder how much my POC MIPS helmet protected me from a helmet without it. Nevertheless, even if MIPS did, I would have had liked to be fully protected. I'm lying here buzzing with a headache.
  • 6 0
 I like that technology is being used to make safer helmets as well. However, the problem with concussion prevention is the movement of the brain in the skull. Unless you can absorb or defect a huge amount of force with a helmet system, when your skull stops, your brain will still keep moving and cause a concussion.
  • 1 0
 @drgnarswag: yes, your point supports what I'm trying to convey. Even if MIPS works to reduce deceleration and force, It is not enough protection. In real life use, it did not protect me enough. The door is still wide open to the risk of concussion--MIPS or not. Just don't buy a MIPS helmet thinking there's significant protection against concussion. That would be a false sense of security. I am a real life tester.
  • 2 0
 I think this article is great, it evaporated any doubts I had left. That being said: "reducing the amount of rotational energy that reaches the brain" is different than concussion prevention. It is obviously a very likely, given who designed the system but more time has to go by for it to be conclusively stated.

This could be seen as a legal technicality but really it's a necessary facet of medical advancement: data, data, and more data plus time equals reliable conclusions.

And just throwing this out there, I wish I could splash out for a new mips poc full face lid every time I thrash a helmet.

 @Aust95: I'm with you! I crashed hard a few months back and it resulted with my having a concussion. My helmet was thrashed and didn't have MIPS. I was off the bike for 8 weeks and never thought I'd rid myself of all the issues I was dealing with. Needless to say my replacement helmet is MIPS equipped!

 Have you looked into 6D and their technology? I was looking into a MiPS helmet but the more I look at 6D, I think that is the direction I am going to go. BTW, currently out for 6 more weeks due to a concussion and 5 broken ribs from a BMX crash. @Aust95:

 @Aust95: i would rather wonder if the mips reduced a injury in a crash than wonder if it would have reduced a injury in a crash.

i lawn darted over the bars off a pretty good size jump on my cry 450 10 years ago and was wearing a leate neck brace that I'm pretty sure broke my collar bone and also pretty sure saved my neck.
hope a speedy recovery for you!!

 @mcmaduske: Well yeah, that's the thing. I trust there are great scientists and doctors behind MIPS as well as Leatt and Kali. But because it is behind companies we never get to see them together, discuss the different concepts and decide which really is the best. That's what I'd love to see really. Which do I need for best concussion prevention. Would be great indeed to see that new certification become reality, about the transmission of rotational forces.

Still not sure about hair not being sufficient. What type of hairdress did they test. I've got fairly long curly hair so to stow it under my helmet (so that nothing makes its way to the front tickly my nose, eyes etc) I always use a bandana (currently the Buff type) to tame it before I put on the helmet. It is a huge slip layer and no matter how hard I press, it can always slide. I'm curious whether that thin MIPS layer allows for more movement than my hair.

Unfortunately most (diagnosed or likely) concussions I've suffered without helmet. There was only one that was cycling related and I wore a helmet against probably three or four without. Still, would make a difference so I applaud the development of safer protective gear.

 @mcmaduske: Concussion and broken ribs?! Pain! I feel for you. Rest well and heal good.

I am looking into 6D. It seems like it'd give better protection from linear impacts since the suspension system is like small compressible shock absorbers.
  • 18 3
 We still regard MIPS as unproven technology unless your helmet is so closely coupled to your head that it can't move on impact even a quarter inch. MIPS has not yet hit the mass market big box stores where most helmets are sold in the US. Manufacturers are looking at other technologies with similar effects, hoping to mitigate rotational injury, add to the price tag and sell new helmets.

Summary: Our review finds no radical safety improvement this year that would compel you to replace your current helmet. New technology has finally come to the marketplace, but there are no independent public test results confirming better performance. Some new developments, including MIPS, we consider unproven. Almost all of the helmets described below meet standards and offer good if not excellent protection. We have tested a sample of cheap and expensive helmets and found no real performance differences by price. We recommend looking for a helmet that fits you well and has a rounded, smooth exterior with no major snag points.

 Glad it got linked early. A smooth helmet is way more important than MIPS. Put a MIPS and non equiped helmet on. Press and move the helmet to feel the slip plane. Your hair is the slip plane.

 MIPS places a hard plastic liner between your head and the nice pliable, compressable EPS liner so that the EPS deforms less in an impact. This is because MIPS spreads the impact load over a larger area, through its structure and through its extended surface area, and internal/inter-material shear, when transmitting force between mediums. This greater distributed load will deform the EPS less, meaning an increased axial deceleration, which is the last thing I want. You could argue that the same volume of EPS is deformed but over a greater area, however I want my head to travel as far as possible into the EPS in a crash because that deeper travel means slower deceleration. Also, the MIPS' hard surface is uncomfortable to wear against my head in the two MIPS helmets I own, so it gets removed. Irregularities, bumps on a users' head slightly deform a helemts' EPS liner creating a more custom fit over time. MIPS prevents that happening. I prefer the other helmet makers' options.

 Here's an irony: The large centre dorsal spine/fin on TLD D3 helemts is a rotational injurys' bedfellow. It's a pity because they look so cool, but for safety's sake it should be removed to prevent it catching on the ground and acting as a lever or fulcrum for inducing rotational acceleration in a crash. A helmet's exterior is suppossed to be a smooth round or oval to reduce imparted rotational it slides unencumbered by spiky bits catching/digging into the ground. D3s have those stylistic sharp ridges and peaks...and now they have MIPS to counteract this risk.
  • 2 0
 MIPS needs space between the head/liner and the EPS/EPP core to work. This means that you need to size up the helmet in order to get a good fit. A bigger helmet means more weight on the head. It also means linger distance between the head and the outer surface of the helmet leading to more rotational force. Today there are other rotational systems that don’t need upsizing.

Mips is a steam hammer to crack a wallnut. Just put a bandana on and go ride.

 JohSch, I keep reading similar statements from people constantly on forums. I'm sure you understand basic physics enough to know that when my 210 lbs moving at over 15 mph hits the ground headfirst, the amount of force required to have my helmet slip isn't the same as wiggling it around while I just standing there with it on.

 @TheOriginalTwoTone: This isn´t my website, just shared it here.

But I´ve talked to other people in the industry which have tested MIPS vs theirs and others normal helmets and decided not to implement it into their own helmets.

So it´s as often, you have to believe in it (or not).

 I bought my son a MIPS infused Bontrager helmet. It was the same cost as the non-MIPS helmet and I can see the benefit, however marginal, of this technology. Going to College/University, we spend thousands of dollars on our brains, what's 100 bucks or more for a helmet to increase the protection of that investment?

 I'd like to see some data from MIPS...props to Kali for showing us some numbers.

 So I am confused. This system is claimed to be around for a while and to of been used in motorcycle helmets. I have road race motorcycles and still have tons of buddies that have done it their whole lives and I keep up with professional racing and I have yet to see One racer use a helmet with a mips tag on it. Even the racers that use Bell Helmets don't have mips-equipped. So when does this really protect our head and if it's so great and been around so long how come no professional motorcycle Racers use them?

 I know a lot of offroad/mx guys have mips helmets. Not sure about road stuff though. Its interesting though, Bell's high end mx helmet doesn't have mips, it has a different system (that I think probably works way better).

 Whatever if the fit isn't right. My son is a longhair and his helmet squibbles about on his head too much for my comfort because of his hairdo. I look at MIPS as a further squishy fit. Especially with DH helmets... no good if the chinbar ends up on your forehead.

 I crashed with the Proframe helmet which had MIPS. It did nothing special in comparison to a helmet without MIPS. I had a bad concussion and the MIPS system cut my head open. I'm not sold on MIPS. With respect to engineers etc, I feel it's a gimmick to get riders to spend more money. Sad when it comes to safety. That said, the Proframe is an awful helmet with a horrible design. Aside from swallowing rocks, the protection just isn't there. Disappointing....

 If MIPS is the best we have, I'll take it. As it is though, it's not enough. We'll still get concussions with it. I did.

Riders would benefit from more budget by companies devoted to development and innovation. Push technology for the protection of riders. I love this sport & don't want to abandon it yet I don't want to suffer another concussion.

The impact testing on that video is questionable because in a real life scenario the skull is attached to a lot of weight (neck, torso, etc.) which can act like a momentum lever to smash a skull downward. Even with reduction of force claimed by MIPS even reduce the forces below an acceptable threshold? It's like either get blown up by a hand grenade or get blown up by a nuclear warhead. There's a lower force in the grenade but in the end it's all the same.

 I agree, until I see numbers proving otherwise mips is a scam. 6d will send you all their data if you ask, it even be up on their website. With how widely used mips is you'd think we'd have something. Bell's high end moto helmet, 6d, and Leatt all have way better systems and I will gladly take the weight/size/price penalty on those when the time comes to buy a new fullface.

 @gdnorm: I wouldn't call increasing public awareness of the importance for helmets to work during linear and rotational impacts to be "fear mongering."

 I have brain damage, epilepsy, and dementia, from a long life of boxing. I have spent a lot of time on this issue for my own personal reasons. I currently believe that many different layers of different densities crushable foam that absorb impacts best related to expected events per use of a helmet is the best protection with current technology. Trust me, rotational brain impacts affected me as much as direct blows, and are not in any way less important to worry about. The problem is executing the protection. Mips is a step in the right direction, and I applaud all efforts. But multiple layers of different densities is possible today. Note- I am not a scientist, and wasn't a great boxer.

 3 years ago I crashed into a tree head first and have suffered with prolonged concussion (diagnose: post concussion syndrome/PCS) since. Science believes rotational forces cause it. I know at least five other mtb-ers in Sweden alone who have suffered 6m+ PCS in the last years so it's not uncommon.

Any technology which reduces the risk of injuries like this is interesting and badly needed. I listened to independent 3rd party testers like Folksam (link by @mikekazimer above) which clearly show MIPS equipped helmets transfer less rotational energy into your head. Went ahead and replaced all mine (and friends) helmets with MIPS versions after. Will never know if they had reduced my injury but it could not have made it worse.

Speaking of money, think for a moment how much it will cost you not being able to work for months, or even years. Add the psychological hardship for you and your family into the equation. Heck, a lot of people go mad from just spending 2 weeks inside a dark room with sunglasses on. Try going from an active lifestyle and riding 6 days a week to struggling to do anything at all. Please tell me that nobody truly thinks an extra €25 for MIPS is not a bargain compared with that.
  • 4 3
 Brilliant idea - but poorly executed. The MIPS system wears out quickly, is not replaceable (according to POC) and is bloody expensive. If I buy a helmet for $300 I expect it to last (without any crashes) for at least a few seasons and not break due to wear. Unfortunately, it would seem that helmet manufacturers are who employ MIPS use it as a marketing tool and wear feature that shortens the lifespan of the product.
  • 3 5
 That is the point. Short life span. Buy another one. Besides the fact it is a complete bs and i believe they can/should be sued for false claims.
Unfortunately the american companies, in general, they own the press. I have not read a review calling out the bs yet. You call out the bs, no more ads on you magazine.
The only ones calling out the bs are other companies that do not want to pay giro the fee for using the "technology". And i call bs on these companies as well, as they jumped on the wagon, then realised mips sales are not taking off.
All we want is helmets without pressure points. Those are dangerous.

 Bell/Giro have a financial stake in MIPS, and are obviously trying to create the impression that it's a must-have technology.

Every MIPS helmet I've tried on has been worse on fit, venting, and noise than its non-MIPS counterpart.

Perhaps things like the new MIPS "spherical" approach will help this. But since modern helmets work by being crushed upon impact, I'd be wary of anything that adds non-crushable layers between head and shell.
  • 10 1
 Hi, can you provide background information on Bell's financial ties to MIPS? Really would like to see this out of personal curiosity!

As an aside to fit, venting and (???) noise; I obviously haven't trail tested as many MIPS helmets as you have, but the two that I own (one for over 2 years, the other less than 2 months) aren't any noisier, nor is their venting poorer as helmets I've owned in the past.

On a final note: As far as I know, all helmets have operated on the principles of 1. deflection and 2. (for the last 20+ years to my knowledge) a "crushable" layer for a while. I don't see the harm in trying to make something safer, for safety's sake.

 @ssteve: The article states the Bell/Giro have a minority financial stake in MIPS. You can read more about that here:

Maybe I have a weird-shaped head, but I've always found helmets with the yellow MIPS layer to fit poorly, have less air flow (due to the yellow plastic blocking air vents), and in some cases make squeaky/creaky noises. I suspect this reflects a poor job of integrating the MIPS layer into the shape and venting of the helmet. My Fox Proframe with MIPS does fit pretty well and is quiet. I have absolutely no problem with MIPS if it doesn't affect other aspects of helmet function or fit, and am all for anything that has even a marginal chance of improving the outcome of a crash.

My point re: Crushable layer is that the thickness of the crushable foam is what allows it to work. Any part of that thickness that is taken up by other stuff, like a MIPS layer or a "spherical" layer interface, will reduce the primary effectiveness of the impact absorbing foam.

I think this article provides some good food for thought:

 @ssteve: Continuing last year's trend, there are many new helmets in bike stores using the MIPS (Multi-directional Impact Protection System - tm) slip plane technology. The trend was boosted by Bell's purchase of a substantial percentage of the MIPS patent-holder company in mid-2014. Most are implemented by a thin layer of material in the top that slides.
  • 1 0
 @Drew-O: Yeah, kinda zoned out on that one...

I thought I had an oddly-shaped noggin. Maybe it's the new normal. No fit issues here. Ventilation and noise have never really crossed my mind either.

I can't speak for the thickness of the helmet's crushable layer in regards to the new design, but having owned many helmets I don't see a measurable difference in foam thickness between my MIPS lids and non-MIPS. Have yet to take a caliper to them though..

Looking back at what I've read in the past, ideally we'd all still be wearing DJ lids with few (or better still none whatsoever) vents. Perhaps MIPS is an attempt to achieve the same effect in a modern (design/form) helmet? Maybe it is just a cash grab, either way I still put it on for every ride and I hope that it's safer than without!

 You apparently haven't tried on many MIPS lids in the last 6-12 months. Beyond that, you clearly haven't tried on many Giro or Bell lids recently. They're doing a better job than any other manufacturer at integrating MIPS at this time. Many of them effect fit and air flow next to none.

As for crushing... wtf are you talking about? If the gutter layers haven't done their job by the time the impact reaches the MIPS layer you're dead or retarded anyways. It's not in there for impact protection. Hell.. if anything it'll help keep a sharp rock or branch from busting you're head open. But it's designed for rotational impact not direct impact.

Man... at least @WAKIdesigns has solid reasoning behind his hatred of all things MIPS.
  • 2 0

They bought into MIPS when it was a very young science. They have progressively helped further develop and improve the technology.

Ultimately it give them the ability to offer MIPS at a lower price point than other manufacturers and the freedom to do things like create integrated MIPS and/or color the MIPS. Ever notice that they've got pink and what not... everyone else pretty much locked in on yellow.

They still have to pay for the tech.

 I'm using a 14 year old TLD D2 "carbon" Its been nice interacting with some folks here - I've learned a lot. Without MIPS I expect to die on my next DH ride. I'm not really superstitious, but I did touch it to dirt before the first ride back at Mammoth in 2004. The helmet was a 2003 on close out. RIP me.

 Good to see research done into safety that can be expencive and does deserve to cost a little bit more for peace of mind, is the thing worth protecting, but better to learn not to fall on your head, although not always possible when pushing the limits I can not remember the last time I fell on my head, is that just getting old or too much brain damage or just have not hit my head riding in many years

 No one has suggested MIPs isn't a good idea. According to the seminar on concussions our snow school received last season MIPS also hasn't been proven independently to provide additional protection either. While MIPS can't hurt the best thing is to always use a good helmet in good condition.

 @mikekazimer Y U no come to Gothenburg to ride with da trolls... also I hope you visited Öhlins while in Stockholm

 Sorry @WAKIdesigns, it was a super quick trip. Next time I'm in Sweden you can show me your troll trails - I'd love to check them out.

 Forget Mit's. 6D is the new sh*t. Bought one for my girlfriend and she loves it. Perfect fit and super safe.

 Couldn't put up the slo-mo of the actual test?! that would have been the coolest part!

 I'm a little disappointed to see the tests are not run on full dummies.

 Me too. And the main reason is that comparisons are being made between non-MIPS vs. MIPS and specifically they are comparing the angular accelerations measured at the Head CoG in both conditions. My main concern is that if the testing methods result in much higher angular accelerations than would be present if the head was attached to the body via the neck, then when they report the percent reductions in peak angular accelerations achieved with MIPS, they may be overstating those percent reductions that would be achieved with a neck and torso.

These guys are PhD level Biomechanical Engineers though; I would be surprised if they hadn't conducted some full dummy tests as well. Maybe they've already looked into this and found that the percent reductions (in angular accelerations) were similar so they kept using these simpler test procedures. I would be curious to know.

 The real test was done on the dummies buying this BS.

 A lot of MIPS helmets on sale/clearance these days, Wonder why?

 Anything from a previous year is on sale. MIPS or not. Come on now

 I had a look at my first MIPs helmet today. Was surprised at how little technology there is! Its just a coke bottle cut up and stuck inside. Massive waste of money IMO

 How exactly is simplicity related to efficacy? Seat belts aren't exactly complicated, but I wouldn't call them a waste of money. I'm all for any technology that has the potential to reduce rotational acceleration in the event of a crash, whether that's MIPS, POC's new SPIN pads, 6D's rubber dampers, or any of the other options that are emerging.

 Helmets are basically a bunch of styrofoam takeout boxes and cups compacted into a plastic shell right?

 @mikekazimer: seatbelts aren't luxury accessories that increase a vehicles MSRP for the consumer... I'm all for MIPS, and have it in three of my helmets, but the markup value is questionable and seems greedy. Better safety shouldn't be exclusive to those who can afford it.

 @TerrapinBen, I agree, but in many cases MIPS is only $20 more, and there are more and more helmets being released that aren't even available without MIPS.

 @mikekazimer: I like to think my hair will do just as good a job or even if I decide to go skin head, I'm pretty sure the helmet pads will do the job for me

 Simple yes, also extremely effective. Just look at the testing and how much more safer MIPS is compared to a traditional helmet. When it comes to my safety out on the trail, I want don't care how much it is, I wanna be safe.

 @mikekazimer: can they point to any real life studies that MIPS actually does anything for you? Oops, yeah, they can't, but hey it's really "cool."

 @mikekazimer: @bikerboywill and depending on the helmet manufacturer the up charge can be minimal. cheap insurance if you ask me...

 @TerrapinBen: seat belt was created by an Volvo engineer in 1959.

Volvo could've patented the crap out of it like MIPS did, but they didn't, they gave it out for free because they realized how important it was. MIPS is not essential like the seat belt, it's just incremental, if anything.

Unfortunately seat belt vs. MIPS is not a straight forward comparison, if someone patented the helmet concept and charged an arm and a leg for it, that'd be a different story.

 @hardingsan: the cost isn't the problem for me. My problem is the manufacturer have created tests to show how good their product is and that you definitely need it to be safe, there is no indipendant data showing they are better. Adding another layer to a helmet creates a worse fitting, less comfortable and heavier helmet.

 @aut117, here's one third party study that evaluates helmets with and without MIPS for you:
  • 2 1
 @mikekazimer: right, because these are super realistic, especially when you talk about rotational injury. I am talking about real world accidents and injuries such as the Harborview Studies. There is no such thing. It "may" reduce rotational injury, not "will" or is even "likely to," look at their marketing materials.

 @aut117: I'm sure that you're more familiar than most with the rules regarding making claims about a helmet's performance - companies simply can't claim things like "it will prevent concussions" - that's just asking for a lawsuit.

It's also hard to have real world studies when the technology is fairly new - in the grand scheme of things, there simply aren't that many riders out there with MIPS-equipped helmets yet. It's also difficult to determine the exact mechanism of injury after the fact, in other words, determining whether or not it was a linear or rotational impact that caused a brain injury. I'm all for more studies and research - I want helmets from all manufacturers to be as safe as possible.

 @mikekazimer: I'm curious if the efficacy of MIPS has been verified by independent studies or only tests done by the manufacturers of the product?
  • 2 0
 @mikekazimer: right, which proves my point. It may or may not do anything for you, it's theory. It's great helmet manufacturers are thinking of ways to potentially improve rider safety and invest in new technologies, but there is no need to drink their "revolutionary" marketing Kool Aid (which I'm not saying you are). You can still have the same concussion wearing a MIPS helmet.

 Maybe I'll anti up the extra $20 when I feel like my sh!tyy brain is worth that much... and there's real evidence that mips works. @mikekazimer:

 @stevendotwang: BMW developed the first ESD after an engineer crashed in the snow. They also realised the significance of the technology and rather than holding the Patent they gave it away to other car companies. The engineer was a little put out at first, until he realised millions of ppl where saved by his research and design then he was happy BMW did what they did.

 @dirtyrig: Not up until last winter it hadn't. don't know if that has changed. Can't hurt but better is to inspect and replace your helmet regularly.
