　　Pros Supremely comfortable Great ventilation Light Excellent coverage Easy eyewear storage Cons Expensive Bennett Shane While Giro road helmets continue to share subtle hints of design language with predecessors dating back to the 90s, the Aries Spherical ($300) claims big gains in performance and makes a subtle shift in aesthetics while acing the Virginia Tech Helmet Rating safety test, receiving 5/5 stars.

　　At first glance, we were smitten with the look of the Aries because, frankly, the Giro aesthetic needed a change, and Giro nailed it. A more prominent Aura II reinforcement arch across the top allows for a beautifully minimal appearance and a strikingly low profile. So compact is the Aries that we had to double-check the label inside to confirm we were indeed holding a size large. Up front, a boxy central vent is cut aggressively into the leading edge, creating a racy and muscular look. Out back, Giro spared no material from being cut away, creating an aggressively tapered shape that balances the looks of the helmet perfectly. The finish on the vents isn’t just clean, it’s razor sharp. The contrasting gloss and matte panels work together to create a seductive visual depth across the helmet’s surface. I learned quickly that this masterpiece of form was equally impressive in function.

　　The fit of the Aries is excellent and that’s no surprise. Giro figured out bike helmet fit ages ago by using data to map the human head and dial in the shape of their helmets to fit the greatest possible number of people. That said, the Aries is noticeably more luxurious and secure than the range-topping Giro helmets of yesteryear, despite minimal use of padding, which has been replaced with an array of thoughtfully sculpted internal channels. On the road, the Aries continued to pamper while remaining perfectly positioned. Bumps, wind gusts, and full gas sprints never caused any slips or wiggles. Thanks to this supreme stability, we could ride with minimal tension on the Roc Loc 5 adjustment dial, which made the Aries feel even lighter and comfier. 

　　Giro claims that the Aries is 2.3% better vented than its predecessor, the Aether. While it’s hard to validate this numerical improvement, we can confirm this helmet moves prodigious amounts of air through its structure. Its venting is so effective that it may not be the optimal helmet for riding in cold conditions. Adding to the Aries’ robust strategy for moisture control, a new DryCore brow pad hides a silicone rubber strip inside its lower edge, where Giro claims it diverts sweat away from the eyes and outward toward the temples. While we can’t confirm with certainty that DryCore diverted sweat in this way, it did help keep the forehead dry and sweat off our lenses. 

　　Perhaps most importantly, the Giro Aries is the best-performing helmet ever tested by the Virginia Tech Helmet Test Lab. This safety rating speaks to the effectiveness of MIPS Spherical technology, which uses a ball-and-socket design intended to redirect impact forces away from a riders head during a crash, with the goal of reducing the risk of concussion. 

　　Even after all this praise, $300 is a lot to pay for a helmet. Certainly, there are helmets that compete with the Aries and cost considerably less. However, if you want the best and cost saving is not a priority, the Giro Aries Spherical is our top recommendation.

　　Pros Lighter than many helmets costing double or triple Great fit High comfort level Cons Limited ventilation Looks a bit dull Bennett Shane The Lazer Tonic KinetiCore ($80) is the brands entry-level helmet road cycling model, but managed to impress, even compared to the range-topping Vento Kineticore aero helmet. At $80, it makes a strong case as a clear standout in the entry-level price point of road helmets. 

　　The Tonic’s fit is excellent, and we found it more comfortable than the range-topping Vento. The simple twist-dial adjustment knob in the retention system is a refreshing change after fussing around with the Vento Kineticore’s ScrollSys adjustment. The Tonic is also much lighter than the Vento. All this prompts the question, why is the Tonic so inexpensive? For starters, the ventilation of the Tonic is limited, meaning that riding hard in hot conditions could cause excessive sweating. The Tonic also has a very safe aesthetic, verging on being a bit dull to look at. It certainly doesn’t look expensive or race-inspired. Storing sunglasses in the Tonic wasn’t a great experience either, so we ended up just clasping the glasses to the back of my jersey collar. 

　　The Tonic uses Lazers KinetiCore technology,  a MIPS alternative that features crumple zones in the EPS foam intended to provide rotational impact protection in the event of a head-impact crash. The system promises to work great, as the Virginia Tech University Helmet Lab awarded 5 out of 5 stars to The Tonic Kineticore after crash-testing.

　　Overall, riding in the Tonic was great, although it did start to feel a bit warm even just cruising around town in mildly warm spring weather. The Tonic stayed in place well, thanks to its perfect fit and ample, soft padding. Aside from not having a great place to easily store sunglasses and its somewhat bland appearance, we don’t have any other complaints about it. We could definitely see the Lazer Tonic KinetiCore as a great helmet for anybody, from a novice rider to an accomplished racer who wants to save some cash for club rides and races.

　　Pros Sleek profile Excellent coverage Reassuringly snug fit Cons Slightly heavier weight Bennett Shane POC’s entry-level road helmet, the Omne Air MIPS ($170), is a prime example of technology trickling down from higher-end offerings into a more affordable, albeit heftier helmet. The extra weight of this helmet is noticeable, but so is the excellent ventilation, sleek profile, and enhanced visibility of AVIP (Attention, Visibility, Interaction, and Protection) on the colorway we tested. 

　　Beginning with the ventilation, the Omne features five front vents and three rear vents. The three central front vents are matched at the rear, at the opposing end of deep and wide internal channels. It’s a simple but effective layout for ventilation that works well to move air freely over the top of your head. 

　　The Omne Air profile looks much better than many helmets, which are nearly double the cost. While the aesthetics of some POC helmets have polarized opinions, the Omne takes an understated approach to create a look that’s hard to resist. On the back of the Omne Air, POC has included the option of AVIP (Attention, Visibility, Interaction, and Protection), which is a fancy way of describing the color (very bright) orange. In all seriousness, it’s an effective means of getting motorists’ attention as they approach from behind and actually looks surprisingly cool. It also comes in several less brilliant color options.

　　Branding on the Omne Air is still prevalent but more subdued relative to other POC products from the past. If anybody asks, the acronym stands for Piece Of Cake, but the brand is pronounced “Pock”, not “P, O, C”. 

　　Once a head impact has become unavoidable, MIPS Integra steps in to redirect impact forces away from your head, with the goal of reducing rotational forces that reach the brain. Virginia Tech Helmet Lab testing resulted in a score of 4 out of 5 stars for Omne Air. We found the fit of the Omne comfortable and secure but not airy like the Ventral, POCs range-topping road helmet. Nevertheless, we stayed cool and dry while riding in warm conditions with plenty of climbing involved. No pressure points developed, and the plush padding and excellent fit kept the Omne perfectly positioned throughout our rides.

　　For riders looking for a well-vented helmet with a great fit and sleek Scandinavian aesthetics, the POC Omne Air MIPS is a smart choice at a great price. 

　　Check Price at REICheck Price at Amazon Runner-Up Best Road Bike Helmet Trek Velocis MIPS Specs MSRP $300 Weight 240g (Medium) Rotational Impact Protection System MIPS Air Number of vents 16 Available sizes S, M, L Virginia Tech Helmet Safety Rating 5-star Colors Viper Red/Cobra Blood, Dark Aquatic, Black, White, Red, White/Nautical Navy

　　

　　Pros Prodigious ventilation Uber-compact profile Liberal use of carbon fiber for crazy low weight Unconditional comfort guarantee Easy eyewear storage Cons Expensive Not a great application of BOA Bennett Shane The Trek Velocis MIPS ($300) is a beautifully minimal, lightweight, and well-ventilated helmet. A sleek, rounded profile is punctuated by 18 vents and clad with Trek’s OCLV carbon fiber, which gives the Velocis a contemporary and race-ready stance. Tipping the scales at just 240g in size medium, this range-topping option from Trek makes a strong impression right out of the box.

　　Inside the shell, you’ll find the MIPS Air — the lightest and best-vented version of MIPS — integrated into the padding of the Velocis. MIPS systems are designed to redirect impact forces away from a riders head during a crash, with the intention of reducing the risk of concussion. For those of us who like to keep padding fresh, the MIPS Air padding is designed to be removed and washed. Just be sure to remove the padding carefully, as it’s connected mechanically to the shell of the Velocis. Although this version of MIPS prioritizes weight savings and ventilation, it’s worth mentioning that the Velocis did receive a 5-star rating from the Virginia Tech University Helmet Lab. This 5-star rating is even more impressive, given the extremely minimal appearance and feel of the MIPS Air and the entire Velocis helmet.  

　　The fit of the Velocis is comfortable, if not exceptionally luxurious. The interior feels firm and secure, with no obvious pressure points. Unlike the Giro Aries, the Velocis is felt at all times while riding.  A three-position yoke in the back of the Velocis allowed for a customized fit and secure hold. Thanks to the yoke, we were also able to get a 60cm head into a medium, which was a nice benefit to both looks and weight savings.

　　Strangely, the 360° BOA® fit system was an unfortunate drawback to the Velocis. While we typically get along well with BOA® generally, we found the feel of the BOA in the single lace adjustment system sloppy and the squeaky sound it made during adjustments unbecoming of a $300 helmet. We suspect the BOA dials need more structure and support than the single-lace adjustment system can offer, so while the idea is great, we felt the execution was not. 

　　Once the adjustment was sorted and we were out riding, the Velocis was a joy to wear. Trek sculpted the leading edge of the Velocis to minimize interference with peripheral vision, which helps when riding with a more aggressive head and neck posture. Sunglasses are easily and securely stored thanks to channels cut into the interior foam. The Velocis is also noticeably quieter than other helmets in its class, speaking to its sleek and minimal shape. Many riders commented on the Velocis, mostly complimenting its looks and conspicuous display of carbon fiber.

　　The Trek Velocis MIPS defends its high price point well with a long list of features and a tangible quality that few helmets can match. Its ability to balance the demands of weight-savings, aerodynamics, and cooling makes it a great choice for racing or hunting trophies and crowns on Strava.

　　Pros Aero performance in any temperature Excellent fit and comfort Less bulky and lighter than some aero helmets Cons Slightly bulkier than some some non-aero options Bennett Shane The Giro Eclipse Spherical ($250) is an aero road helmet with excellent ventilation and respectably low weight, making it a one-helmet solution for any riding or racing scenario. Despite its balanced approach that prioritizes ventilation and weight savings, Giro claims that the Eclipse Spherical is the fastest road helmet they’ve ever tested in the wind tunnel, and its relatively lightweight for an aero model at just 270 grams in a size medium. 

　　Giro achieved best-in-class ventilation and weight savings in the Eclipse Spherical by incorporating its proprietary Wind Tunnel venting system and pairing these active intake vents with deep exhaust channels inside the helmet’s shell to accelerate cool air across the rider’s head and force warm air out. It sounds so easy to reduce weight and boost ventilation by simply removing material from the helmet, and yet, no other aero helmet to date can match the Eclipse in these areas. This speaks to Giro’s iterative approach to helmets. They don’t have to go back to the drawing board for every new helmet but rather draw on learnings from dozens of their best-in-class designs from the past few decades to achieve whatever blend of attributes they seek. 

　　Speed and comfort are great, but the actual job of a helmet is protecting the rider’s brain in a crash, and here again, the Eclipse Spherical proves its value by scoring 5 out of 5 stars in testing by Virginia Tech University’s Helmet Ratings Lab. This excellent level of protection is made possible in part by the helmet’s namesake, MIPS Spherical Technology, which uses a ball-and-socket design to redirect impact forces away from a riders head during a crash. MIPS Spherical was a great choice for the Eclipse, as it doesn’t compromise weight and ventilation the same way earlier and less advanced iterations of MIPS liners did. In the Eclipse Spherical, the MIPS system blends seamlessly into the helmet and goes entirely unnoticed. 

　　Throughout the Eclipse Spherical, all the iconic Giro details remain constant. Giro’s Roc Loc 5 Air Fit system, with its 2-way adjustment, makes for a secure and comfortable fit at the base of the occipital lobe. Iconic+ AntiMicrobial Padding and lightweight webbing with easily adjustable guides pamper the rider’s head on even the most grueling days. Like other Giro models, we found the fit to be quite comfortable, with a crowd-pleasing shape that should work for most riders.

　　If you’ve been wooed by the free speed of an aero helmet but have been put off by the weight, bulky looks, and lackluster ventilation in the past, the Giro Eclipse Spherical might just be the helmet that wins you over. Giro states, and we agree, that the Eclipse Spherical delivers speed without compromise.

　　(Photo/Specialized) Pros Lightweight Vents well Durable, high-quality construction Priced well below S-works models Cons May not fit round heads well Bennett Shane Specialized recently redesigned their Propero road helmet and the new Propero 4 ($200) is virtually unrecognizable compared to its predecessor. Borrowing design elements from its more expensive S-Works siblings like the Evade 3 and the Prevail 3, the Propero 4 is a low-profile aero model that comes in at a more reasonable price of $200.

　　Specialized used Computational Fluid Dynamics (CFD) and wind tunnel testing to focus on both aerodynamics and ventilation. Despite looking like it has a limited number of vents, 12 total, internal channeling does a great job of moving air from the front intake vents across the head to the exhaust vents in the back. The smaller number of vents also contributes to the Propero 4’s clean, streamlined look, which we feel makes it among the better-looking lids on the market today.

　　Inside the Propero 4, Specialized went with a MIPS Evolve for rotational impact protection. On top of that, it was tested in Virginia Tech’s independent helmet test lab and earned the highest 5-star rating. We found the Tri-Fix webbing splitter by the ears to hold the straps flat and away from the ears, plus they can adjusted to find the ideal position for your head shape. It’s also offered in both “classic” and “round” fits, so most people should be able to find one that matches the fit of their cranium. 

　　With a measured weight of 308 grams in a size medium, it isn’t the lightest helmet around, but it feels light on the head thanks to its excellent ventilation and great fit. Overall, we feel the Specialized Propero 4 is a great new helmet that provides aero advantages without the bulky looks and higher price of most other aero models.

　　Pros Excellent ventilation Very lightweight Low profile Unique styling Cons Expensive Bennett Shane The original Protone made a big splash because it was a great concept a uniquely styled helmet with heaps of ventilation up front, a gloriously compact profile, and aerodynamically efficient exhaust ports out back, all at an impressively low weight. Now, the Kask Protone Icon ($300) retains the overall aesthetic of the original but updates the internal shaping to increase ventilation while decreasing aerodynamic drag. A new retention system, which Kask calls Octafit+, includes a new cradle, stabilizer, and rubber inserts that connect to a wider section of the occipital lobe, providing a more secure hold.

　　According to Kask, some subtle changes have been made to the exterior structure as well, aimed at improved aero efficiency, but thankfully, these are subtle and don’t change the look at all. Cycling brands have to iterate to stay relevant, and it’s often a case of newer not meaning better, so we applaud Kask for staying true to the winning formula of the original Protone in developing its successor. 

　　After putting the Protone Icon on, it was clear that the Octafit+ system gives it a more comfortable and stable fit than the original. Vertical adjustment of the cradle is very easy, with just a gentle push up or pull down in either direction, so finding the correct tilt and a comfortable hold is a breeze. The leather chin strap is a great touch as it is better able to resist grabbing and irritating the skin on the throat and should help keep the strap looking better over time than polyester, which is more affected by sweat and friction.  

　　Kask does not use MIPS rotational impact systems, instead using an internal testing protocol called WG11 to evaluate all its helmets rotational impact performance. Kask claims that the level of friction generated by the head form used in MIPS testing is too great and that the Kask head form provides a more realistic test protocol. Sadly, the Protone Icon has not been tested by the Virginia Tech University Helmet Lab, so its ability to protect against concussions is less quantifiable than some of its competition.

　　Out on the road, the Kask Protone Icon performs perfectly. The torrential airflow and low weight combine to keep things cool and relaxed during even the most searing efforts. And in those moments, it’s nice to know that your helmet is saving a few watts of drag and helping you look like a boss. 

　　Check Price at Competitive CyclistCheck Price at Amazon Best of the Rest Specialized S-Works Evade 3 Specs MSRP $300 Weight 350g (Large) Rotational Impact Protection System MIPS Node Air Number of vents 9 Available sizes S, M, L Virginia Tech Helmet Safety Rating 5-star Colors Metallic Deep Marine, Black, White, Red, Hyper Green/Dove Grey

　　

　　Pros Unbeatable ventilation in an aero lid Compatible with ANGi crash sensor Excellent finish quality Cons Magnetic clasp is fiddly Expensive Heavier weight Bennett Shane The third iteration of the original aero road helmet, the Specialized S-Works Evade 3 ($300) seeks to maintain its status as the most aero helmet available, while upgrading cooling and comfort. In fact, Specialized claims a 10% improvement in ventilation over the previous model, and the additional air movement was certainly noticeable out on the road.

　　The S-Works Evade 3 makes a great initial impression. The overall finish of the shell and vent edges is exquisite, and the lack of any visible bare foam lends it a contemporary, luxurious look. The profile is unique, with a somewhat rectangular stance and a large shelf at the lower trailing edge. This look won’t please everyone, but trade-offs between aesthetics and big aero gains are nothing new. 

　　The Evade 3 is compatible with ANGi, which is a live tracking device, crash detector, and safety beacon that can be added to the Mindset adjustment harness. Once the optional ANGi sensor is paired with the Specialized Ride app, any force consistent with head impact triggers an alarm on your phone and starts a countdown. If you are unable to stop the alarm before the countdown ends, the app sends text and email messages to your emergency contacts with your location. A subscription is required for the ANGi system to operate. 

　　Speaking of crashes, the Evade 3 received a 5-star safety rating from the Virginia Tech University Helmet lab, which is not all that surprising given its high price tag. The Evade 3 features the MIPS Node Air, which is the most comfortable, best-ventilated, and lightest version of MIPS available. This low-profile version of MIPS is intended to protect the brain from rotational impact forces in certain types of crashes, and its 5-star performance in Virginia Techs impact testing makes a strong case for its effectiveness.

　　As with other magnetic buckles, we found the one on the Evades chin strap quite fiddly and perhaps a solution in search of a problem. Once the Evade 3 was secured and adjusted, however, we found the fit to be excellent and did not notice the helmets extra heft at all. 

　　After riding in the Evade 3 in warm conditions, we can confirm it vents much better than many non-aero helmets, let alone other aero helmets. We would have no hesitation taking it out for a full gas race or ride with lots of climbing in warm weather. To us, this is the clear reason to choose the Specialized S-Works Evade 3. It isn’t the sleekest or the lightest, but it will provide a boost in cooling during the most grueling races and club rides compared to many aero models.

　　Pros Compact profile Good ventilation for an aero helmet Low weight Clean aesthetics Cons ScrollSys adjustment system is difficult to operate Pressure points in front and rear Expensive Bennett Shane As its name suggests, the Lazer Vento KinetiCore ($300) generates excellent airflow, both inside and out, to keep you cool and comfortable with less aerodynamic drag. As for KinetiCore, it’s a MIPS alternative that features crumple zones in the EPS foam intended to reduce rotational impact forces that reach the brain in the event of a crash. Given the 5-star rating in Virginia Techs independent helmet impact testing, KinetiCore promises to work as advertised. 

　　Unboxing the Vento Kineticore, we were immediately impressed with the finish quality. The edges of the vents are finished cleanly, and the contrasting matte and gloss-painted panels give the helmet a seductive look. It’s also light, at just 285 grams, nearly 20% lighter than the S-Works Evade 3, a perennial favorite in the aero helmet category.

　　We found the fit to be a bit wide, with a moderate pressure point immediately evident at the front of the helmet. We found this surprising since we’ve always gotten on well with Lazer’s fit, going back to its iconic Genesis design. The back of the Vento Kineticore is remarkably comfortable since the tightening mechanism, dubbed ScrollSys, is built into the rear shell of the helmet instead of pressing against the occipital lobe. 

　　While we found the ScrollSys mechanism easy to understand and operate, the feeling of adjusting it was harsh, loud, and jerky. There was a lot of back-and-forth before we found the sweet spot. Our experience with ScrollSys slightly diminished my opinion of the Vento Kinteticore because it would be an experience we’d have every time we put the helmet on. We enjoyed RollSys, as found on the Genesis, but this iteration is an example of newer and different not always resulting in a better experience. 

　　Out on the road, the Vento Kineticore performed very well, moving air efficiently through its well-placed vents to keep the head cool and dry. The Vento Kineticore was also noticeably quiet at high speeds, compared to other helmets we tested. While we still felt a bit of pressure at the front and back, the feeling didn’t get any worse after a few hours of riding, so we suspect that the Vento Kineticore is just a better fit for those with slightly wider or rounded head shapes.

　　We also applaud Lazer for offering some bold color combinations. The red and plum test model looked amazing when worn with the bright red S-Phyre RC903 shoes, which are made by Lazer’s parent company, Shimano. For faster riders and racers who want everything in a helmet — low weight, great ventilation, watt-saving aero performance, and test-proven head protection — the Lazer Vento KinetiCore justifies its premium price and deserves a close look.

　　Pros Forgot-it’s-even-there comfort Light Excellent coverage Compact profile Cons Ventilation could be better Bennett Shane The Trace MIPS ($260) is unmistakably a Smith helmet. The Portland, OR-based brand has developed a bold design language that’s quite likable. An aggressive stance in the front transitions to a gracefully arched form at the back. It all flows together gracefully, and the contrasting gloss and matte finishes give the Trace a nice visual depth. 

　　The fit is excellent, with even pressure, supple padding, and perfectly balanced mass from front to back. Adjusting the Trace is quick and easy, thanks to a simple, quiet, and solid-feeling twist dial. The retention system dubbed Vaporfit uses minimal material and is barely noticeable against the occipital lobe once the Trace is on and adjusted. 

　　Wed hoped that Smith would use MIPS Air in a $260 helmet to maximize comfort and breathability. However, Smith opted for a basic MIPS liner that connects to the inside of the EPS structure. It’s a non-issue, though, because Smith controlled the interior shape and pad placement so well that the Trace feels just as comfortable as helmets with MIPS Air. 

　　Though the independent helmet impact test lab at Virginia Tech has yet to test and rate the Trace MIPS, its construction, supplemented with an MIPS liner and Koroyd, provides confidence in its protective qualities. Koroyd is a material designed to dissipate energy during a crash before it can reach your head. The Koryod material is clearly visible in the construction of the Trace, a honeycomb of protection sandwiched between the EPS foam and MIPS liner. 

　　On the road, the Trace is brilliant, keeping you cool, dry, and essentially disappearing into the background. The Trace stays firmly in place over rough sections of the road, giving us confidence that it would make a great helmet for not only the road but also for gravel riding. If youre looking for a boldly styled, super-comfortable, lightweight, and safe helmet for road, gravel, and even commuting, the Smith Trace MIPS makes a compelling argument to be your next helmet.

　　Pros Prodigious ventilation Uber-compact profile Lightweight Affordable Cons None Bennett Shane The Abus Powerdome ($130-$170) is a lightweight, compact helmet that prioritizes ventilation and comfort. The fit differs from some better-known helmet brands, as the Powerdome sits a bit higher on the head rather than surrounding it. 

　　We like the idea of a helmet achieving decent aero performance through a super compact profile versus a bulbous shape that adds weight and sacrifices ventilation for increased laminar airflow. The Abus Powerdome achieves the former, with a tidy profile that is well-appointed with vents, including a huge air inlet at the top of the helmet, modeled after the Powerdome of high-performance cars and which gives the helmet its name as a functional design element.

　　Due to its low weight and compact shape, we honestly forgot the Powerdome was even there during some intense rides in hilly terrain. Rough descents were no bother, as the Powerdome stayed in place perfectly at all times. The strap system is simple and free of flapping at high speed. All in all, the experience of riding in the Powerdome was better than its mid-range pricing would suggest.

　　Although our test helmet did not come equipped with a rotational impact protection system, Abus offers the Powerdome with a MIPS system as well. Without MIPS, the Powerdome sells for $130, and with MIPS, the price jumps to $170. MIPS creates a low-friction layer within the helmet that allows the outer layer of the helmet to move 10-15mm during angled impacts, with the goal of limiting the rotational force applied to your head and reducing the chance of a concussion. Since safety is the reason to wear a helmet in the first place, we always recommend springing for a helmet with a rotational impact protection system.

　　The Abus Powerdome achieves impressive comfort, ventilation, and weight savings. We also love the look of it from every angle and were impressed with how quietly it cut through the air. If you want a simple but elegant helmet that is comfortable and looks the part for racing and riding on the rivet, check out the Abus Powerdome.

　　Pros Lighter than many more expensive options Excellent fit Very comfortable Cons Limited ventilation Bennett Shane The Giro Agilis MIPS ($100) is an affordable helmet that hits the mark on fit, safety, and style. A durable outer shell with an impressive array of vents covers a luxurious interior featuring Giro’s renowned fit, industry-leading Roc Loc 5 retention system, and a MIPS liner for rotational impact protection. 

　　Quite surprisingly, we found the fit to be as comfortable as Giro’s range-topping Aries Spherical, which costs $300. Out on the road, the most noticeable difference between these two helmets was the slightly less efficient airflow through the Agilis despite its whopping number of vents. That said, compared to other helmets in the same price point, the Agilis moves air most admirably. 

　　In addition to its agreeable shape, adjustments to the retention system and straps are simple and quick, meaning you can truly customize the Agilis fit and ride in total comfort. It stayed secure while riding at all speeds.

　　At the $100 price point, the only readily apparent shortcomings are found in a few extra grams of weight, and a slightly rougher finish around the edges of the vents. If the protection of both your brain and bank account sounds like a win-win, team up with the Giro Agilis MIPS.

　　Pros Good fit Good ventilation Excellent coverage Cons Looks a lot like a XC MTB helmet Magnetic strap clasp is fiddly Big branding Bennett Shane The Bell XR Spherical ($225) helmet doesn’t look like most road helmets, but what it may lack in looks, it makes up for in spades with a great fit, impressive ventilation, a little extra head coverage, and the incorporation of MIPS Spherical technology. 

　　Beauty is in the eye of the beholder, but it’s easy to see some XC mountain bike influence in the XR Spherical. Its overall shape, especially around the lower trailing edge, is rather square and chunky, and it drops down at the back of the head more than most road helmets. The gradient fade paint scheme is cool but is somewhat diminished by the enormous Bell logos flanking the XR’s trailing edge. 

　　The fit is sublime, which is no surprise given Bells, and sister company, Giros, decades of experience making cycling helmets. Pressure is perfectly distributed around the interior, and luxurious padding is combined with intelligently sculpted channeling to create an easy but secure hold. The Float adjustment system is smooth and quiet.

　　As of publication, Virginia Tech University has yet to test the Bell XR Spherical. That said, given the above-average head coverage and the use of MIPS Spherical technology, which uses a ball-and-socket design to redirect rotational impact forces away from a riders head during a crash, it looks and feels quite protective.

　　If youre in the market for a road bike helmet that provides a little more coverage than most, or youre looking for a versatile option that can span your road, gravel, cyclocross, and XC mountain biking needs, we think the Bell XR Spherical is a solid choice.

How We Tested the Best Road Bike Helmets In addition to reporting on the latest news, technology, and product releases, our cycling writers and editors take their cycling and safety very seriously. Our staff is in tune with the latest and greatest products on the market, and more often than not, we learn about and test new helmets before they even hit the market.

　　Review author Bennett Shane personally tested the vast majority of the helmets included in this review, and weve added one that was recently tested by one of our other team members. Bennett lives in Portland, OR, and has been road cycling seriously for the better part of the past two decades. After racing road and gravel for over 10 years, Bennett has traded the timing chip for long rides on lonely roads throughout the Pacific Northwest and more time with his young family. He has also worked for a number of prominent brands in the cycling industry, which has given him unique insight into the latest cycling gear and technology. Bennetts cycling and industry experience combined have helped him develop a keen ability to tease out the subtle performance differences between the products he tests. In addition to the road bike helmet review, Bennet has also tested and reviewed the best road bike shoes and cycling bib shorts, along with numerous other product categories, including the best road bike tires.

　　For the purposes of this buyers guide, we rounded up 13 of the best road bike helmets available in 2024 to put through their paces in the real world. We chose a diverse selection of brands, styles, and price points with the goal of having a representative sample of the broad cycling helmet market. Testing these helmets side by side allows us to directly compare them and identify performance differences to form the basis for our recommendations. Each models design and construction were closely examined before taking them out for numerous rides of varying lengths in a range of weather conditions and temperatures. While riding, we scrutinized important performance characteristics like fit, comfort, ventilation, adjustments, and features, and even though it doesnt affect performance, we even considered each models style.

　　

　　

　　Though his shirt may suggest otherwise, review author Bennett Shane takes his product testing very seriously; (photo/Ben Guernsey) Buying Advice: How to Choose the Best Road Bike Helmet Road bike helmets meet a broad spectrum of needs, from keeping us comfortable to looking and performing our best and, of course, protecting us during the worst of the worst. We have analyzed and tested a diverse lineup to help you understand the options and pick the best helmet for your next ride.

　　Types of Road Bike Helmets While you can road bike in just about any helmet you choose, helmets designed specifically for road cycling are the best fit for the task. Road bike helmets aim to balance sleek and streamlined designs with lightweight constructions and good ventilation while remaining protective in the event of a crash and head impact. They generally fall into two categories: lightweight and vented or aero. They differ from their mountain bike counterparts mostly by their lighter weight, reduced head coverage, and lack of a visor. If youre looking for the best mountain bike helmet, dont worry, weve tested those too.

　　

　　

　　Lightweight and well-ventilated helmets, like the Giro Aries Spherical pictured here, are versatile and make the most sense for most riders; (photo/Bennett Shane) Lightweight-Vented Road Bike Helmets This is the more common style of helmet that the majority of road cyclists choose for most types of riding. Airflow will be better in a lightweight-vented helmet than in an aero helmet since air is directed through vents and onto your scalp rather than along the helmet’s surface. Riders who sweat more than average, spend a lot of time climbing, or often ride in extreme heat will benefit more from the superior cooling power of a lightweight-vented helmet. Can’t decide between an aero or a lightweight-vented helmet? The good news is that most brands have begun to incorporate aero shaping into the back and sides of lightweight-vented helmets without compromising ventilation at the front and top of the helmet, where it is most needed. The Giro Aries Spherical, Kask Protone Icon, and Trek Velocis MIPS are all super lightweight and well-ventilated options.

　　

　　

　　Models like the Lazer Vento KinetiCore have more aerodynamic shapes to help reduce drag; (photo/Ben Guernsey) Aero Road Bike Helmets Most helmet manufacturers offer an aerodynamically shaped helmet that is designed to smooth airflow over your head, resulting in faster speeds on the bike at the same level of rider effort. Keep in mind that these aerodynamic gains do typically incur marginal losses in ventilation, and add some weight to the helmet. Aero helmets may also perform better in a temperate or cold climate, as they shield your head more from cold air and light rainfall. While most aerodynamic equipment is a massive commitment of resources, an aero helmet can reduce your aero drag without draining your coffers. Research also indicates that, dollar for dollar, an aero helmet is a more effective way to reduce aero drag than frames and wheels. Models like the Giro Eclipse Spherical, Lazer vento KinetiCore, Specialized S-Works Evade 3, and the Specialized Propero 4 are good examples of aero road bike helmets.

　　

　　

　　For a helmet to protect your head and be comfortable, its important to get the correct size; (photo/Ben Guernsey) Helmet Fit Helmet fit will be personal to everyone. Some helmets will feel more oval in shape, and others more circular; some will feel more luxurious, and others more minimal. With some adjustment and fine-tuning, you should be able to achieve a comfortable and safe fit with any helmet in this guide, provided it’s the correct size.

　　A great first step is to measure the circumference of your head just above your ears in centimeters. Taking this step will quantify which size helmet you will be able to wear in each model. When you looking at helmets, look for the centimeter range corresponding to each size in the manufacturers size guide or printed on the box. There is no standard centimeter range for “small”, “medium”, and “large” sizes, so knowing the actual centimeter sizing of your head can save some time here. Whenever possible, it is always a good idea to try a helmet on before buying to ensure it fits properly.

　　Once the correct size is chosen and the retention system, tightening mechanism, and strap systems are adjusted to your needs, you will ideally have a snug but accommodating fit without any pressure points. The helmet should also cover your temples easily and come close to the tops of your ears. When swaying your head side-to-side, the helmet should stay firmly in place. 

　　

　　

　　A helmets straps are key to keeping it on your head in the event of a crash. When adjusted properly, it should be secure, with the straps laying flat and not conflicting with the ears; (photo/Ben Guernsey) Chin Straps A helmets strap system connects the helmet’s straps beneath your chin and keeps the helmet in place during a crash. When adjusted properly, the outer junctions of the straps by the ears should sit comfortably below your ear lobes, and both sections of the strap should be as close as possible to your head to minimize flapping in the wind. Under your chin, the strap should fit so that you can slide two fingers between the bottom of your chin and the strap, ensuring you can breathe comfortably. The chin strap is always adjustable, so it can be dialed in to fit the users head shape. The straps around the ears are typically also adjustable, though the systems vary slightly between brands and models to allow the user to position them to avoid unwanted ear contact.

　　

　　

　　The adjustable harness and its tightening mechanism, like this one on the ABUS Powerdome, are used to fine-tune a helmets fit for security and stability; (photo/Ben Guernsey) Adjustable Harness or Retention System The adjustment harness/retention system counters the chin straps and provides a secure hold at the back of your head, with many modern helmets wrapping tension around the entire head. Most helmets enable adjustment of the entire retention system at the rear interior of the helmet. By adjusting where the retention system is anchored inside the helmet, you can dramatically change the interior volume and fore/aft tilt of the helmet to perfect the fit for your specific head shape. Ideally, by adjusting the retention system correctly, you will place the adjustable harness and its tightening mechanism so that it cradles the base of your occipital lobe.

　　Tightening Mechanism You’ll use the tightening mechanism on the adjustment harness every time you put on or remove the helmet to fine-tune the fit. Some companies use BOA dials like you’ll find on many shoes or some other sort of simple twist dial. Other companies use more complicated mechanisms with varying success. This part of the helmet just needs to work, and its operation should be intuitive, fast, and quiet while performing the important function of keeping the helmet snug, secure, and comfortable on your head.

　　

　　

　　Most helmets feature some type of rotational impact protection system, like the Bell XR MIPS Spherical, which has dual shells that can move independently of each other with the goal of reducing forces transferred to the brain; (photo/Ben Guernsey) Rotational Impact Protection Rotational impact protection systems have become relatively standard in cycling helmets over the past decade or so. MIPS Multi-directional Impact Protection System is the industry leader and the most common form of rotational impact protection. Most brands have licensed some iteration of this technology or developed a proprietary system to achieve similar results. The goal with MIPS and similar systems is to create a low-friction layer, or slip-plane, within the helmet that allows the outer layer of the helmet to move 10-15mm during angled impacts, thus limiting the rotational force applied to your head/brain, and reducing the chance of a concussion. MIPS itself now takes various forms and iterations, including a more standard MIPS liner, MIPS Spherical (dual shells that function like a ball and socket), MIPS Integra, and MIPS Air, which incorporates the technology into the pads themselves.

　　Other brands have created their own technologies that aim to provide the same type of rotational impact protection with different designs. Lazer has developed KinetiCore, which involves small isolated blocks of EPS foam within the helmet that are designed to crush and crumple on impact and is used in the Tonic KinetiCore and the Vento KinetiCore. Bontrager uses a cellular structure called WaveCel in some of their helmets that is intended to work in much the same way. Similarly, Smith incorporates Koroyd into many of its helmets, including the Trace MIPS, which is a cellular structure like WaveCel that is meant to crush and crumple on impact while allowing air to pass through.

　　Safety Rating All helmets must pass tests to be certified for sale in their respective countries. Since 1999 in the US, the Consumer Products Safety Commission (CPSC) is the certifying agency that must approve a helmet before it can be legally sold. In Europe, the cycling standard is CE-EN1078. Most modern helmets that are sold in multiple markets pass both certifications. In some cases, cheap products purchased online may not meet these certification standards, which is why we recommend that cyclists always buy reputable name-brand helmets.

　　Since we do not perform impact testing on the helmets we test and review, we have come to rely on the independent test lab at Virginia Tech for quantifiable data regarding the protective qualities of bicycle helmets. As of the publication date of this article, they have tested 193 different road, mountain, and commuter cycling helmets. Using specialized equipment, they evaluate each helmet using 24 impact tests. They measure a helmets ability to decrease both linear acceleration and rotational velocity to determine how well each model may reduce the risk of concussion. Their numerical results translate to a star rating, 1-5, with 5 being the highest and most protective. The lab has not tested every model on the market or included in our review, but many of the models listed above have been rated. In fact, our best overall road bike helmet, the Giro Aries Spherical, is the top-rated model for protection that they have tested to date.

　　

　　

　　Light is right, right? The Giro Aries Spherical weighs in at a feathery 271 grams in a size medium; (photo/Jeremy Benson) Weight As with most things in the sport of road cycling, weight is a consideration for helmets as well. While it is not the end all be all, lighter is generally considered better if all other things are equal, and helmets must pass the same certification tests irrespective of weight. The weight of the helmets we tested varies between 230 grams and 350 grams, so the differences between them may seem pretty significant. In reality, a 350-gram helmet is still relatively lightweight, though it will feel slightly heavier on the head than a featherlight 230-gram model. That said, riders focused on endurance riding or road racing will generally be most concerned with weight, as even an extra 50 grams can increase neck strain with each passing hour on the bike.

　　Function Over Form? Even though a bike helmet is a great example of form following function, it’s important to like the way your helmet looks. Consider the arrangement and finish of the helmet’s vents. Vents should be arranged in a way that’s pleasing to your eye, augmenting the helmets overall shape. Vents should also be finished cleanly, without rough edges of foam visible. Also, consider the helmet’s overall shape and profile. Does the helmet look overly bulbous once you have put it on, or does it have a compact, streamlined form? Remember that the back of the helmet is the portion most visible to people when you are riding together. It’s worth noting that brightly colored helmets, including silver and white, also increase your visibility to motorists while you ride.

　　

　　

　　While helmets are designed to protect your head, we always appreciate a little style as well. The Lazer Vento KinetiCore looks great when paired with the Shimano S-Phyre RC9 shoes; (photo/Ben Guernsey) Accessory Integration Integration with accessories is becoming more common in helmets. Some helmets have dedicated spaces for storing sunglasses, and others enable lights to be clipped to the helmet at the back and sides for night riding. Specialized has developed the ANGI (Angular and G-Force indicator) system, which is a crash detection sensor that can be purchased separately and added to your helmet. ANGi requires a subscription, but this little device can notify your emergency contacts in the event of a crash. ABUS has also developed a sensor called QUIN that aims to function in a similar way.

　　Value The helmets we tested vary in price from $80 up to $300. While spending top dollar may get you more premium finishes, better ventilation, and fancier features, even the least expensive helmets we tested will serve you well if youre operating on a tighter budget. If youre a recreational or more casual rider, or you simply arent concerned with having the flashiest and most expensive gear, then a helmet like the Giro Agilis MIPS or the Lazer Tonic KinetiCore will get the job done at a fraction of the cost of the more expensive options. Regardless of price, the most important thing is to get a helmet that fits properly and to wear it whenever you throw your leg over the bike.

　　Frequently Asked Questions About Road Bike Helmets How much should I spend on a road bike helmet? Any type of cycling can be very expensive, and the costs arent limited to the latest bikes and components. Even a fancy helmet can set you back several hundred dollars. Its hard to put a price tag on head protection, however, but thankfully, many brands make budget-friendly models that perform nearly as well as their more expensive counterparts. They may be slightly heavier, not as well-ventilated, and perhaps not as stylish, but even a less expensive helmet will protect your head much better than none at all. And, even less expensive models must pass the same certification tests as the high-end models, and many of them perform better in Virginia Tech testing. So, just because a helmet doesnt cost as much doesnt mean that you have to sacrifice head protection in most cases.

　　How do I find the right fit? A properly fitting helmet is critical to your comfort and the helmets protective efficacy in the event of a crash. The first thing you need to do is get the correct shell size. Trying a helmet on is a surefire way to find the right size, so we recommend doing that whenever possible. Alternatively, measuring your head will show you what size you need. Using a soft measuring tape, measure the circumference of your head just above the ears to find your size in centimeters. If you dont have a soft measuring tape, a piece of string and a ruler can be used instead. This measurement should fall within the recommended size range of one of a helmets multiple shell sizes. Helmet manufacturers have size charts on their websites where you can find the sizing information for each specific model.

　　Do I need MIPS or another rotational impact protection system? Rotational impact protection systems like MIPS have been around for the past decade or so and have become pretty ubiquitous among all types of cycling helmets. Most, but not all, helmets these days come with some form of MIPS or another design that is intended to work similarly. While there is some speculation about the effectiveness of these systems, research suggests that they do help reduce the rotational forces that reach the brain in certain types of impacts. Now, even a helmet without a rotational impact protection system will protect your head from direct impact and help to dissipate impact forces. That said, we are happy to have additional safety features built into helmets, no matter how small the added protection may be. So, the answer is no, you dont need MIPS or something similar in your helmet, but well take all the protection we can get.

　　Will an aero helmet actually make me faster? Aerodynamic helmets are designed to allow air to move more freely around and over the helmet with the goal of reducing drag. They do this by having smoother surfaces and more sculpted designs than their all-around counterparts. An aero helmet will almost always have less drag than a helmet that isnt specifically designed to be super aerodynamic, and most have undergone extensive wind tunnel testing to ensure they work as intended. In general, an aero helmet will provide a marginal gain in efficiency, which, when added up over time can result in a more substantial savings of time and energy. That said, aero helmets tend to have a slight reduction in ventilation and a slight increase in weight, comparatively, so that is something to be considered. Still, if saving a few watts and seconds is important to you, an aero helmet can help you do that, and it costs a lot less than an aero bike or aero wheels.

　　If I crash and hit my head, should I replace my helmet? Yes. Helmets are designed to protect your head by absorbing impact forces through crushing and cracking of the EPS foam and outer shell. Any time your helmeted head impacts the ground, the structural integrity and protective qualities of the helmet can be compromised and it should be replaced. Even if there is no visible damage to the foam or any other part of the helmet, there may be damage that cannot be seen. It is always recommended that you replace your helmet after it has taken an impact. Some brands even offer crash replacements at a discounted rate.
