Ridden And Rated - Six Helmets

Oct 24, 2016
by Vernon Felton  
I clearly like black helmets. All of these helmets, however, are available in a wide range of colors. So if you feel a deep kinship to eggplant, turquoise, puce or chartreuse, rest assured, your color needs can be met with any of these lids.

Not so long ago, you were faced with two choices when considering a new helmet: either a full-bore, full-face storm trooper option or the kind of wispy, head thong you might expect to see in the peloton at Le Tour. There was a huge gap there in the middle, which was strange since most riders don’t pray exclusively at either the altar of DH or the temple of XC.

Fortunately, fuller-bodied helmets came along and offered a more sensible combination of deep coverage, light weight, and decent ventilation. That’s a good thing. Bikes have improved over the years, allowing us to tackle terrain at higher speeds… and with greater consequence. Most of us can use a bit more bucket covering our brains. Here are six helmets worth checking out.


A Quick Word About MIPS and Your Brain

If you want to dive straight into the helmet match up, scroll down. However, since MIPS and other slip-plane technologies crop up constantly in this review, I'm going to parse an entire article down into a couple of paragraphs. Do you need this stuff in your next helmet? Here goes...

Right now your brain is happy. It's just sitting there - a 3.5-pound lump of water, protein, fats and carbohydrates with the consistency of soft tofu - in a soup of blood and cerebrospinal fluid. It's at peace. It's content. What would be bad, right about now, is if your soft and squishy brain - laced as it is with a 100 billion neurons and a vast array of nerve fibers - suddenly slammed into the hard and unforgiving walls of your skull. Your helmet is designed to reduce the chance of that happening.

Helmets “cushion” the blow of an impact to your head by spreading the impact over a wide area of the helmet and reducing the energy that’s actually transferred to your head during the impact. Your helmet, to be less geeky about this, acts as a barrier that absorbs the energy of a sudden blow. How do they absorb energy? Most bike helmets feature a crushable foam (EPS) liner. It's basically a high-grade version of the stuff that disposable coolers are made from, and it's covered in a thin plastic shell. That plastic shell reduces friction in a crash, helps disperse impact energy and also helps keep the EPS liner together during an impact. But when it comes to absorbing energy it's mainly a foam thing. Or at least that's historically been the case. Helmet manufacturers wanted to stop skulls from breaking, so they created testing protocols that ensured that all certified helmets (that little EN or CPSC sticker in your helmet) reduce energy (measured in Gs) to a level deemed acceptable (generally, either 250 or 300 Gs depending on the standard in question).

How MIPS works in a crash.

These days, however, more attention is being placed on the question of how to reduce concussions. That's because more evidence has surfaced showing that concussions are a far greater problem than most of us once thought (think early dementia, etc.). You can get a concussion from a direct blow to the head. Growing evidence, however, suggests that rotational accelerations are very likely to cause concussions.

Rotational accelerations? Think of it this way. Linear accelerations (what we've been trying to slow down with our EPS foam liners) generally involve situations in which the head is moving in a straight line and comes to a sudden stop (or is struck by an object moving in a linear fashion). That's why the bulk of impact testing protocols involve dropping a helmet with a weighted head form in it directly onto an anvil at a specific height and speed.

During rotational accelerations the head is generally twisting or receives an angled impact that causes the head and its squishy contents to rotate, twist and, in some cases, shear. Bad news.

This is why more and more helmet manufacturers are adopting new technologies to reduce the rotational energy. At this point, MIPS (Multidirectional Impact Protection System) is the most popular. MIPS is a slip plane - a thin layer of plastic nestled against the foam liner that is said to reduce rotational accelerations by allowing the helmet’s liner to rotate independently around the slip plane during an angled impact. 6D has created its own concussion risk-reducing system called ODS (Omni-Directional Suspension), which features a series of plastic/rubber bumpers sandwiched between inner and outer EPS liners. When an angled impact occurs, the two layers compress and slide against one another, which (like MIPS) should reduce the amount of rotational forces transferred to the brain.

6D's rotation-damping system is called ODS.

Do you need MIPS or ODS? Here's where it gets murky. I can't tell you that one technology is better than the other because currently there are no agreed upon testing protocols or standards for testing and measuring the effectiveness of these technologies. The helmet industry and safety associations are working on it. In the meantime, the manufacturer's are testing in-house and claiming reductions in rotational acceleration. Again, we don't have an apples-to-apples comparison here or even, to be blunt, complete agreement on how the apple should taste.

If you are a skeptic, you might dismiss all this as so much snake oil - just another means of selling a product. You might argue that your helmet already slips (to a certain degree) on your head during a crash - that your sweaty scalp is your own personal MIPS device. While we can't debate precisely how effective MIPS or ODS is at reducing the risk of concussion, the odds are good that these technologies help to some degree. Is it worth paying a bit more money? I'm not going to tell you what to believe. I, however, have been knocked unconscious several times and have a family tendency towards early dementia. I'll take every extra bit of protection I can get. That's my bias, if you will. Okay, on to the damn review already.


Bontrager Lithos MIPS helmet review
Bontrager Lithos MIPS

Bontrager’s Lithos MIPS sports the same core features as the rest of the trail-slash-enduro helmets in this review - extended rear coverage, a tilting visor (to accommodate goggles), and a well-designed fit system. It also sports a few noteworthy perks, including Blendr - the cleanest POV camera/headlight mount that I’ve seen on a helmet to date. You can snap a GoPro or Bontrager Ion light into the thing in nanoseconds flat. The helmet also sports a MIPS slip-plane. What’s not so awesome? At 450 grams this helmet is a bit porky. Also, unlike the other helmets in this review, the chinstraps are not routed through the EPS foam liner itself, which means that on hot days, you have more of the soggy, sweat-soaked straps snuggling up against the sides of your face. It’s not a deal breaker, but at this price, it’s a surprisingly unsophisticated touch. One big perk? If you crash and destroy the helmet within a year of purchasing it, Bontrager will replace it for free.

Bontrager Lithos MIPS Full Review

Lithos MIPS Details
• Weight: 450 grams
• MSRP: $174.99 USD

• ‘Blendr’ video camera/light mount is brilliant
• Pairs well with goggles--plenty of visor adjustment
• Crash replacement offers some peace of mind

• A bit heavy
• Chin strap routing could be improved

6D ATB-1T Helmet

One thing that’s immediately noticeable about the 6D helmet is that it’s big. The upside? This thing is the king of half-shell coverage. It sits low on your head. The ATB-1T is also big - as in thick. 6D’s unique design pairs two EPS layers, between which are sandwiched 27 rubber dampers that allow the foam layers to slide around during an angled impact. You can easily push the inner liner with your fingers and see that, yup, ODS truly allows the two shells to move independently of one another. Cool. As in neat. Because, no, this is not the coolest helmet in terms of ventilation. 6D claims otherwise, but ventilation is better on most of the other helmets in this review. The general fit is good- the helmet features a nice, large dial on its retention system and an effective four-position height adjustment. Kudos, as well, on the Fidlock magnetic buckle on the chinstraps, which snaps quickly and easily into place. This is a well thought out helmet. However, it is also noticeably heavy at 500 grams.

6D ATB-1T Full Review

ATB-1T Details
• Weight: 500 grams
• MSRP: $269.95 USD

• Innovative & unique slip-plane technology
• Magnetic buckle is very easy to operate with numb fingers

• Heavy

Giro Chronicle MIPS helmet
Giro Chronicle MIPS

The Chronicle MIPS is a new helmet from Giro. While it looks a whole lot like the Montaro, the fit is a bit different - the Chronicle sits a bit lower on your head than the Montaro. It also forgoes the Montaro’s integrated camera mount and goggle grippers. Why, then, did I include it here? Because it costs a hundred friggin’ bucks! Damn. And, yes, it also includes a MIPS layer. Double damn. Moreover, the fit is excellent and ventilation is very good. The Giro Feature used to be one of the go-to options for more affordable helmets, but the Chronicle is better on every front. While the harness adjustments are nice and indexed, my sole complaint with the Chronicle is that the adjuster dial on its Roc Loc 5 harness is tiny and consequently harder to adjust with cold, gloved fingers than the larger dials on the Troy Lee, 6D, Specialized, etc. Otherwise? Outstanding.

Chronicle MIPS Details
• Weight: 360 grams
• MSRP: $100 USD

• Great balance of weight, features and price

• Smaller dial on fit system is harder to adjust while wearing gloves

Specialized Ambush Helmet
Specialized Ambush

A bit of extra weight is generally what you have to accept if you are going to run one of these trail or “enduro” helmets. The Specialized Ambush essentially flips the bird at that notion. At 310 grams it is noticeably lighter than just about any helmet in this genre. The ventilation is also without equal. This is my absolute favorite helmet for warm weather riding. Specialized tucks the fit adjust dial into the back of the foam liner - it’s easy to operate and helps make their Mindset 360 retention system incredibly comfortable. There’s no dial digging into the back of your head with this lid (when you’re bald, you feel these things). Moreover, the fit is rock solid- no slipping about when the trail gets rowdy. If you’re a fan of running goggles, the Ambush is an excellent choice, as it offers the greatest range of visor adjustability (tilt) of any helmet here. The ambush is a lean, mean thing, which also means that there are no camera mounts and no slip plane-type devices. Whether or not that matters is up to you. Again, at this price, I’d prefer it if Specialized added some kind of extra concussion-reducing doohickey to this lid.
Ambush Full Review

Ambush Details
• Weight: 310 grams
• MSRP: $180 USD

• Lightest of the bunch
• Pairs well with goggles - plenty of visor adjustment
• Best fit adjustment system out there
• Excellent ventilation

• At this price it should feature MIPS or some other slip-plane technology

Troy Lee Designs A1 Drone Helmet

Troy Lee Designs A1 Drone

Troy Lee’s A1 offers one of the most comfortable fits of any trail-riding helmet. It sounds silly to say it, but the padding on the helmet has a lot do to with it. It’s just the right type of dense and plush. It’s also removable, so you can wash and de-funk it. The fit system works well - again, there’s a nice big dial to snug things up here. Downsides? The visor doesn’t offer a huge range of adjustment, and while it's anchored by nicely finished aluminum knobs, those little buggers have a tendency to back out. Ventilation is not great despite a whole lot of big vents. I’ve run the original A1 and another A1 Drone for a couple of years now and sweat dripping down in my eyes is more of a problem with this helmet than with others in warm conditions. On the upside, the A1 is a great choice for cooler weather. Weight is reasonable on the A1 and the price is good for such a nicely finished helmet. If you want MIPS, TLD now offers the A1 Vertigo MIPS for $215.

TLD A1 full review

A1 Drone Details
• Weight: 344 grams
• MSRP: $125.10 USD

• Most comfortable padding of the bunch
• Good cool-weather helmet

• Despite plenty of vents, ventilation suffers. Not a great choice in summer heat
• Small range of visor adjustment

POC Tectal Helmet

POC Tectal Helmet

I found the POC Tectal one of the more comfortable fits on the market - a step up from the game-changing Trabec, to be sure. Ventilation is good. There are some breezier lids out there, such as the Specialized Ambush, but the Tectal is upper tier here as well. I’d have absolutely no reservations running it on very hot days. The Tectal's retention system offers nice indexed tweaks via a dial at the back, which is easy to adjust - even when you’re wearing full-finger gloves.
POC reinforces the EPS foam liner at key points in the Tectal with aramid fibers (the stuff in folding tire beads). If you’re willing to spend a few more bucks, POC’s upper-tier Tectal Race gets the aramid reinforcement spread throughout the entire EPS liner. POC also embedded a Recco reflector in the helmet (something you generally find on snowsports helmets). The reflector can help search and rescue workers in a helicopter find you if you are unlucky enough to ever have search and rescue workers looking for you.

What is missing here? There’s no MIPS or alternative slip-plane device that might help reduce rotational accelerations and, therein, reduce the likelihood of concussions. Admittedly, you might not care, but at this price, it feels like an oversight.

Tectal Full Review

Tectal Details
• Weight: 360 grams
• MSRP: $190 USD

• Recco reflector helps search and rescue operators (in helicopters) pinpoint your location, should you get lost in the wilds.
• Good ventilation
• Nice build quality

• At this price it should feature MIPS or other slip-plane technology

Helmet Review

Which Helmet Would I Buy?

There’s no shortage of good helmets out there. Consequently, you may find yourself wondering, “Why didn’t you include the ________?” [go ahead and fill in the blank here]. Well, the log in the picture above is only so long - I couldn’t fit them all on top of it. Or, to be less facetious, you have to draw the line somewhere. The six lids in this review are ones that I’ve used and found deserving of more attention. Each has its own merits.

If you’re aiming for maximum protection, the 6D is a compelling option. At this point, it’s impossible to say that 6D’s ODS system is more effective than MIPS at reducing the risk of concussion (see that brain bit, in this story's lead), but their unique system shows promise. If I didn’t give a damn about MIPS or slip planes, I’d go with the Specialized Ambush, wish feels like an XC helmet, but offers much more coverage.

The Bontrager Lithos isn’t cheap, but offers both cool features and MIPS at a reasonable price. The POC has the best overall fit and finish, but is a bit pricey given the lack of a slip plane device. The TLD is a solid and attractive choice for the money, but I’d like to see better airflow through the center of the helmet.... All of which leaves me staring at the Giro Chronicle.
Giro Chronicle MIPS helmet
Giro's new Chronicle MIPS helmet - for my money, it's the lid that brings together the best balance of features, fit and value.

Here’s the thing - every lightweight, half-shell bike helmet on the market is a one-time use product. In other words, you smack your helmet once and you toss it in the trash. Remember, the EPS liner is meant to crush - it doesn’t spring back into working shape again. It does not feature a resilient multi-impact liner (what you'd find, for instance, in a football helmet and some snowsports lids). Kali's upcoming MacDuff dirt-jump/street helmet is a multi-impact model, but as it stands, we mountain bikers live in a largely one-crash-and-it's-in-the-trash helmet reality. Well, I have a hard time paying more than a hundred bucks for any helmet that has to be binned after one wreck. The Chronicle is the right choice for me given my budget, but it also kicks ass in terms of fit, ventilation, and overall comfort. Oh, and it has MIPS. Given all that, the Chronicle is nigh unbeatable.

 I'm not generally the guy that does the "you didn't test the one I like" thing, & I suppose you're expecting this, but I'll be your huckleberry: The Bell Super, especially as it's been recently revised to version 3, is perhaps a helmet that should be in this test, seeing as I see it on more heads (including mine) than any of the other helmets in this article.

 I agree - not trying to heckle, so I'll begin with a positive. This type of review format is awesome. Problem is, the price spread is huge. If you're going to compare a top-of-the-line product from one company, make it a cross comparison. Where is the new Giro Mataro? Micro-dial, MIPS, GoPro mount, etc. That's a direct competitor to the Troy Lee A1, but one of those helmets fits great and the other is terrible. My suggestion is to create product classes based on features and cross-listed by price. Some helmets might lack features and be very expensive and it's important to know where they all fall into the market if you're going to do a range review like this.

PB has listened to their critics & started doing these "showdown" style reviews, even though it costs them a lot more time & resources(& they only get one article out of it, rather than 6 if they reviewed each helmet separately.)

The only reason I even spoke up is because it's a bit of an elephant in the room situation: the Bell might very well be one of the most successful helmets our sport has ever seen, & I spent a lot of the review wondering one specific question: how do these compare to the model I've been happily riding with for 3 years? Especially because I take Vernon's point about helmets being disposable to heart, & usually look for last years model on clearance rather than buy anything along the lines of the new hotness.

 I wonder why football helmets, which often are custom made and cost up to $2000.00, do not use the MIPS technology. Since concussion is a much greater concern and there are much greater resources then cycling. MIPS does not help. Otherwise it would have been already used in other sports.
What does HELP to reduce injuries is good inner shell design. Hotspots provoke damadge. I have tested all the helmets in this review except for the most expensive one. They are all poorly designed, except for the tld a1 and the specialized. All the other helmets provide poor protection because the massive hotspots. Poor inner shell design. The bell stroker has a better fit than all these helmets.
Just try on some italian helemts like KASK REX if you need something that fits good and it is well built. Most of the helmets on this review, except the TLD, have weak rear adjustments that will not hold in a crash.

POC: bad shell design, weak rear adjustment, it only fits glasses with flat arms (like their own)

GIRO: very poor fit. Poor rear adjustment. Push the helment on your head. See hot spot. Try an italian helmet. Repeat. No hot spots.

BELL: same as giro but slightly better. The cheaper model, the STROKER is a better helmet. Does not fit sunglasses well.

SPECIALIZED: really dislike this company, but they know where to copy the good stuff. Otherwise is cheaply made.

TLD: the best in the group but way too hot.

BONTRAGER: poor strap placement, better fit than average.

RECAP: Hotspots greatly increase injury. An helmet with poor inner shell design will have hotspots. Most of these helmets have
huge hotspots. Get yourself a Kask Rex, it is another cathergory compare to all the helmets in this review.

 A few weeks ago in an article related to kali helmets, a guy showed up in the comment section talking about the awesome advantages that kali offered to reduce the risk of concussions effectively. The whole thing was BS but this guy seemed to reach people around here. The new marketing ways are impressive. Mips is basically the same, another ripoff, another crap to raise the helmet price and make money easily without offering significant benefits. We'll often see this kind of innovations about concussions from now on, cause anything that sounds to reduce brain injuries sells and sells a lot. Too bad money always goes before health.

 IMHO, focusing on the rotational component of crashes is a red herring at best. 6D's ODS does quite a bit more then MIPS in reducing the force of more common low speed impacts to the brain. MIPS really only adds additional protection against the rotational component of a crash. Frankly, if you have hair, that alone adds a level of slip compared to the relatively sticky rubber headforms that MIPS have used for testing.

What I think is far more important is the additional protection that ODS provides in low speed impacts that are at the concussion or sub-concussive level. Most EPS-foam only helmets need to be sufficiently firm to guard against skull fractures in higher speed impacts, but doing so reduces their ability to absorb lower force levels that can cause concussion or sub-concussive impacts. The ODS design has hourglass- shaped rubber dampers suspending two foam layers to reduce force transmission in low speed impacts while maintaining the ability to reduce the force of high speed impacts.

Here is a review of MIPS from the non-profit Bicycle Helmet Safety Institute which is 100% funded by consumers: www.bhsi.org/mips.htm

Of pretty much all the crashes I've had, from the lost front tooth to the fractured collarbone and snapped wrist, rotational forces have been taken care of by my hair (probably) and the chinstrap (definitely) My latest, spearing tree, resulted in mild concussion and a sore neck.
If there had been some kind of impact suppression system (e.g. Sorbothane or D3O) I think my brain would have lost a few less cells Smile

 I totally agree with this ^^^
None of these helmets really address low speed crashes that you might experience on the trail. These helmet will save your life and keep your skull from fracturing but won't be very soft at all in a typical low speed fail. 6D addresses low and high speed impacts via decoupling the shell AWAY from your skull. Definitely worth the money for the amount of engineering and thought put into it. Regarding the review, mine doesn't really feel that heavy and the ventilation has never been an issue even in the middle of summer here in NC. Love this helmet.

 MIPS is "snake oil" - perfectly worded in that report. All helmets move rotationaly to your head when you crash, and as that article points out, so many helmet designs are counter-productive to what MIPS is trying to achieve in the first place. Looks like the early POC design is the only one that actually applied the technology correctly.

 Problem is, we know it's snake oil, studies show it's inconclusive, yet the words "should have slip plane tech at this price" are in the article. Marketing wins again, drop mips into a helmet and double the price

 My friend has a MIPS helmet and I have inspected it. My first though was, hair would have more effect than that little yellow thing. My second thought was, really? $40 extra for that little made in China bit of plastic that looks like it cost about one point two cents to make? It's a bit of a joke, in my opinion.

 @bluumax: Did you read my bit about MIPS/ODS and other slip plane technology? If not, give it a spin. In the end, you might feel that investing in any kind of slip plane is a crap idea (until, at least, there are standard testing protocols for actually measuring rotational acceleration). If that's your position, I understand it. That's not an unreasonable position to take. As I said in the review, I'm not telling anyone what to think about MIPS or ODS when the technology is still very much in its proving stages. However, I think it's likely that both technologies reduce rotational accelerations. By how much? That's completely up in the air at this point. And, clearly, every execution of MIPS is going to yield different potential benefits, based on how well or poorly executed it is. As I noted in the article, I've busted several helmets, been hit in the face on occasion and simply lived the kind of life where concussions have been a reality....all of which is why I am personally biased towards extra protection--particularly when the helmet in question costs a lot and is only good for one smack to the head. As I said in the review, if MIPS/ODS didn't matter to me, I'd go with the Specialized Ambush.

 That's a good point for sure, and it looks like there will be a lot more helmets that provide absorption of low speed impacts as well coming out soon. I'm def keen on checking out the Leatt line when they come round...

 @vernonfelton: I thought the overall format of this review is what pinkbike readers have been asking for. The reasons for your choices - giro montara and spesh ambush - show the intelligence and well informed depth of knowledge that pb mgmt has been seeking in a new writer. Great review - it's exactly what the site needs.

 @vernonfelton: sorry mate, i think you've misunderstood my comment, I know MIPS can reduce rotational forces etc, the problem is the mindset of "reduce rotation force=less chance of concussion" is not yet conclusive, so yes you can show it reduces a force, but there is nothing to show they reduce the chance of concussion, Its like me selling you a set of bars that reduce arm pump by reducing high frequency vibration, but the actual cause was youre gripping the bars too hard, yes the bars reduce the frequency and you can show it through graphs, but it wont stop arm pump. Another example is knee braces, proven to reduce the forces acting on ligaments, but every single study since the 70's has shown there is no link between wearing a knee brace and reduction of knee injuries.
My point was more that marketing is slowly trying to push people into thinking that unless they shell out for MIPS or ODS they are increasing the risk of a concussion, the media has a responsibility to take this claim with a pinch of salt and look at it objectively, because the next thing you see will be MIPS becoming a requirement at races etc. BTW i know you covered this at the start and i still think its a really good article, wasnt a shot at you, more a shot at how the whole thing seems to be unfolding industry wide

 @bluumax: The concussion thing is, indeed, a thorny and twisted subject. That is true. A lot of people want a concussion-proof helmet, which is an impossibility to make. For a whole lot of reasons. Any one individual's concussion threshold is going to be different from the next person, based on gender, age, size, shape of their skull, prior incidences of concussions, etc. What's more, you can get a concussion from a linear impact as well as from rotational impact. Hell, you don't even have to hit your head to get a concussion. Someone shoves you hard in the back and your head suddenly swings forward--that'll do it too. There is a decent amount of scientific literature that indicates that rotational accelerations are, indeed, a strong contributor to concussions, so I think it's good that the helmet industry is looking at ways to address that--in fact, it's necessary. It is frustrating for everyone who wears helmets, however, that there still isn't agreement on how the testing for rotational accelerations should be conducted. Naturally, it shouldn't be rushed--the test protocols should actually yield results that matter in the real world--but it would help us get beyond the snake oil concern. At any rate, thanks bluumax for writing in. I do agree that there is a whole lot of marketing out there and that some companies are claiming more than they probably should, which is why I wrote the piece noting my own bias (at the upper price ranges) for helmets with slip plane devices, but also noted the helmet that I'd recommend if readers didn't buy into MIPS/ODS: that helmet is the Specialized Ambush.

 It ain't @vernonfelton's fault that there's no evidence either way on whether MIPS helps outside the lab on the trail. As individuals we can decide that MIPS is snake oil, but the fact is that position is only a data-less hunch. PB isn't, and shouldn't be, in the data-less hunch business. I do wish the review had been a little more skeptical of the idea that one anti-concussion technology is as good as another. But, big picture, I give Vernon and PB credit for spotlighting the concussion issue instead of just puking out another "it's light! it looks rad!" helmet review.

"It ain't @vernonfelton's fault that there's no evidence either way on whether MIPS helps outside the lab on the trail"

But it IS his fault that at least twice he states that slip plane tech should be included given the price of the helmet - a clear if tacit acceptance of the hype around it...

 If you want a concussion-reducing helmet for $100, I think the Kali Maya is a better bet than the Giro Chronicle. I don't have much faith that MIPS makes any difference in the real world, and I believe in the Maya's dual-density foam to protect better against smaller hits that won't crack your skull but will rattle your brain.
  • 1 0
 That's what I'm getting next, but so far I've heard very little on it. Anyone have one?
  • 3 0
 @NotDannyHart: i have one and its my favorite helmet ive ever had. Definitely recommend. Super comfortable. Fits like a glove on my head but that depends on your head shape. Vents pretty well. Light weight . Kali also has a lifetime crash replacement. There is also a review here on pinkbike you can look at.
  • 3 2
 I've had Kali helmets in the past and their liners didn't last (separating layers within months) making their helmets really uncomfortable. The company wouldn't stand behind them either.
  • 2 0
 I like the cone head technology in the Kali stuff but I personally could not get the Maya shape to fit me very well. It's a slightly shorter(top to bottom) helmet and didn't seem to cover the sides of my head above my ears as much as some of the other helmets. I'm sure it works good for most but if you have an egg shaped head it may fit a little high up and short.
  • 1 0
 Yes, dual density. That is the direction. All other sports go that direction. MIPS is pure fantasy. Just a marketing gimmick. 60$ upcharge for 0.5 cents cost increase. Ok, maybe 0.05 cents.
Giro should hire some good helmet designers are their fit is among the worst.

Pinkbike or greenbike?
  • 4 0
 @NotDannyHart: Yep, I have a Maya and is it s good well fitting helmet. And to me, the Cone shaped twin density foam makes sense, when it comes to absorbing low and high impacts. I think that Kali now have helmets which combine ODS as well as the cone twin density foam. My next helmet will be a Kali.
  • 6 0
 I'm still wearing a Fox Flux, one of the few helmets that works with the sloping flat back of my scull I have. Most helmets flop around. The Bell Super which I also have, doesn't work for me (except in winter) due to flopping....

Also, when did $200+ helmets become acceptable? Aren't you still supposed to replace these every three years because the foam hardens? Personally, I like my helmets to be $100s. That way I don't feed bad replacing the regularly.
  • 5 0
 Why can't the industry start a standard rating test that helmets can go through and actually print the results? This way we could see which helmets are best in different impact tests rather than just looking at buzz word technology and fancy colorways.

No disrespect to all the websites and mags out there but most just say obviously we never crashed it but it fit well and looks cool. I've seen some tests on European web mags which do this but the manufacturer should supply this.

First company that does it with good results should sell a load more helmets, everyone thinks POC are the safest, prove it POC of beat there score any other manufacturer.

Result = We get safer helmets which we all want

A repost from my comments from the Leatt 6.0 helmet a few days back Again, 6 helmets tested but no data to say they are any safer even though they have MIPS tech in them. They look sweet! New Tech!!!!! Any safer??????????? Show us the numbers!!!!!! @vernonfelton

 A bit anecdotal, but: The Ambush seems to run large. I had one for a year, and agreed wholeheartedly with everything in the review, except that the Large was way, way too big for my head. In the past I had ridden Large helmets from Spec, and the fit was solid, so I bought the Ambush assuming fit would be the same. I've read at least one other review out there that mentions something similar, so I don't think its just me.

I had to run skull caps or hand-bands to make it even get close to fitting, and even then it wasn't ideal. I later tried out the size down, and that was (of course) just too small for my head, so I moved on to an iXS Trail, which has been great.
  • 2 0
 Ditto. To the point I didn't read your post and said the same down below. Shame cuz the Ambush was the most round shape for my skull and that visor actually was worth its weight in plastic.
  • 1 0
 The Ambush Comp, a lower cost version, was recently released in 4 sizes (SM, MD, LG & XL). The new size being the LG. The new LG size is the one you need as it is smaller than the old LG (now called XL).

 I love the format of this comparison. I like how helmets of different price points are compared against each other. I am certainly on a budget, but I am willing to spend more if there is value gained in those extra dollars spent. Im sure lots of other riders feel the same way. Many sites and magazines have comparisons of different products in the same price point, I feel the format in this write up is much more useful to me. Hope to see more articles like this!!

 @vernonfelton - thanks for shedding light on the whole rotational force issue. Problem is, we're all just in the dark as to what it is we're actually trying to protect ourselves against. And while that made sense, say, 20 or even just 10 years ago, it doesn't anymore. The industry could change that - and it would be relatively cheap and easy. All that has to happen is for the industry to fund a large scale study, like so:

Accelerometers are dirt-cheap (in terms of testing equipment, not in terms of pocket change), and rather thin and light these days. It would be relatively easy to construct a skullcap/beanie with a dozen or so accelerometers, hooked up to a recording device. Produce a few hundred of them, hand them out to riders to wear under their helmets, have them chronicle what kind of riding they do and what happened in each and every crash they had while they had the sensor beanie on their noggin. Do this for a few months, rotate through different demographics (downhillers at bike parks, all mountain riders, free riders, cross country riders, commuters). Then crunch numbers and find out what forces actually apply to their heads - straight on, rotational, oblique, what have you. Crunch the data, analyze what sorts of risks we're actually protecting against, then turn that into modern test standards.

The industry has every incentive to fund this stuff - it would make riding safer (so even non-helmet manufacturers would benefit), it would make helmets comparable (thus allowing for clearer marketing), and it would probably drive home the point to riders that they are at risk (thus driving sales of the new helmet types). Everybody wins - most of all us riders, who'll get to have fun on bikes at lower risk of brain injury.

Compared to what manufacturers spend on sometimes rather stupid and ineffective marketing, endless videos, trade show booths, and so forth - well, it seems like this could be a slam dunk. Just in case anyone in the industry asks your opinion on where they should prioritize their R&D money...

 Well put g-42,especially in comparison to the multitude of conjecture based conclusions people have stated here. The reality is that we don't know, because marketing is mostly more important than reality. I don't know either, but I bought a Bell with mips after a serious head injury, because one more and I might be done.

 One thing that I need to note is that the POC Tectal retention mech fails when the back of the helmet is pushed on. I know it would be a rare way to fall like that, but WTF it should not do that. The POC Tectal Race version doesn't seem to do so, but poorly designed in my opinion.
  • 1 0
 It unwinds, not fails. It's not a good thing but as long as the helmet stays on your head it almost acts as a shock... (Yeah, I bumped the back of my head while wearing a Tectal)

 I love how they push a technology that really has no data proving its claim MIPS More Income Per Sale

 Seems like most manufacturers generally offer non MIPS versions so nobody's forcing you to buy it. Doesn't really seem like a downside to it though.
  • 1 0
 @el-nombre: Only possible downside is MIPS changing the fit/feel. I had a Bontrager Lithos and Smith Forefront with MIPS and without. I don't buy into MIPS but if price was the same it still would've been a no-go due to fit altering of that plastic sheath marketers call MIPS.
  • 2 0
 I've written off two A1s due to major to minor crashes, so I appreciate that you've taken replacement value under consideration for this comparison. I've been using the Smith Forefront for most of this year, and I'm glad it doesn't constantly pour sweat on my eye like an open faucet like the A1 does. Also, the helmet liner on the A1 while plump and comfortable, isn't very durable. I had four A1 liners in total that I rotated since I sweat easily and profusely, and they all eventually would come undone at the seams after washing even inside a garment bag--not to mention they were a pain to put in and take out.
The Smith Forefront doesn't have as much coverage as the A1 but it breathes better and it's lighter plus the adjusting mechanism has finer adjustments but it would definitely lose in this comparison due to price; glad I picked one of the left over ones on sale!
  • 2 0
 Also any thoughts on the size of the 6D helmet? I read that the increased size has the potential to actually increase rotational forces. Thanks for taking a shot at getting all this technology straight. This is the only piece of bike gear that I will always buy the best option on the market regardless of price.
  • 1 0
 This is my concern with the 6D. Heavier weight is gonna take longer to come to a stop. It looks really nice with some great coverage. As always, gonna be a game of compromises.
  • 2 0
 I recently swapped to a 7 Protection M2 trail helmet. Fits excellently, large dial adjust is firm and doesn't slip, dual density foam with Cone-tech, 19 vents that really do keep the head cool and bug mesh under the front vents. Nice low rear area and fits no worries with riding glasses or goggles.
Having previously worn the Fox Flux and the Poc Trabec I have personally found the M2 to be superior. Good colour range for the coordinating conscious and only £59.99 from Chain Reaction.

 Is the "ventilation and cooling factor" subjective? I ask this because the Troy Lee A1 is the coolest (in terms of temperature and general ventilation) that I've ever worn. Back to back with my Bell Super, it isn't even close. The Super feels like I'm wearing an oven. Big fan of the Troy Lee - great fit, looks and ventilation, in my opinion.

 We get this confusing note often, "its hot" or "it's super ventilated man!". So, thanks for pointing this out.

 The 6D significantly increases the lever arm in order to accommodate a slip plane? Sounds counter productive. I tried one on at Sea Otter this year, it was so big, I looked like a giant dick.
  • 2 0
 I'd really love to know how people can talk about the fit of a helmet as if there is one perfect shape for all. In the past month or so i've tried on a few of the ones featured here and none of them felt right on my head, including the A1, supposedly the best fit of all. Whilst i appreciate there will be some plain bad designs out there, the way some people in the comments are harping on about fit as if theres a holy grail shape that they should all be aiming for is laughable. Try on some helmets. Buy the one that fits YOU.

 It has taken me 20 years of riding and racing to realize that the best bike part I can possibly buy is one that protects me. Paying more for the safest possible helmet is the best investment I can make for my family and to prolong my years of shredding. Thank you, @vernonfelton for the article and your perspective on helmet safety.

 What I miss in most helmet (and shoe) reviews is an accurate description of the type of fit. My head is relatively small and not quite round. Most helmets, once adjusted to fit in the fore-aft direction, are too wide for me. Some do get me a good fit. Unless @vernonfelton includes a 3d model of his head I have no idea if this review is useful to me. At least select a couple of people in the office with different head shapes and put the helmet on their heads. It's only five minutes work and it adds a lot to the reviews.

 While it's over simplified but he is right. The hottest most advanced helmet isn't all the great if it doesn't fit right. So many people buy the one they hear is the best from other or looks the coolest but it may not fit you head as well. Some fit some head shaped better than others. I would recommend everyone tries on multiple helmets and get the one that fits the best. They all for the most part do the same thing and are disposable. The really expensive one isn't going to get you another crash. And just because you don't see damage doesn't mean that it's not been compromised and a second impact to the same area could result in more damage to your body than it wout of have if the helmet was new.

 A few years ago discussion on helmets was like - why should I get MIPS at all. Now it seems like every helmet needs it otherwise it is not worth buying. There were other high priced helmets before MIPS and there are still a lot of options not having MIPS at all.

I guess (and please take that guess as a real one) that a well made helmet is more protection without MIPS that one with that funky yellow liner to state it is having a MIPS

...just my two cents

 Just a heads-up (ugh), the Specialized Ambush is a very large large. Even cranked down as tight as she'll go it's still too loose for many normally-large sized heads whether oval, round or narrow. And the medium Ambush is not large enough opened all the way. Fantastic ventilation, the visor is a rockstar and the coverage was nice. After I sold mine unused (other than living room try) I asked the guy who sold it why they parted with such a great helmet. Same reason: large too large.

 Great question. Again, the industry and the safety certifying agencies have not agreed upon how to actually test for rotational acceleration (think glancing, angled hits). That's the key thing here. Until we get some agreement on that, it's all just comparing one test to a completely different kind of test--apples to oranges and all that, unfortunately. It is, without a doubt, frustrating.

 @vernonfelton - just thought to ask here as I had a question after seeing the recent pit viper sunglasses review. How do these helmets do at staying on your head if you push them backwards?
