How the Giro Quarter compares to other aero road helmets
As an avid cyclist, I’m always looking for ways to improve my performance on the bike. One area that can make a big difference is having an aerodynamic helmet to slice through the wind efficiently. The Giro Quarter has been getting a lot of attention lately as a top aero road cycling helmet, so I decided to take a closer look and see how it stacks up against the competition.
When it comes to aerodynamics, the Giro Quarter definitely looks the part. It has a teardrop shape that is optimized to direct air around the rider’s head with minimal drag. The short tail helps air stay attached rather than swirling and creating turbulence. The vents are also carefully shaped and placed to enhance airflow. At 224 grams, it’s lightweight as far as aero helmets go. The Roc Loc retention system offers a snug and secure fit while maintaining adjustability and comfort.
How does the Quarter compare against other leading aero road helmets like the Kask Protone or the Specialized Evade? Well, in recent wind tunnel tests, the Quarter produced lower drag numbers than both of those helmets. It particularly excelled at yaw angles between 10-20 degrees, which represents the range where most real-world riding occurs. While the margins were small, even saving a couple watts can make a difference in an all-out sprint or climb. The tail design and optimized vent placement appear to give the Quarter an edge.
TheQuarter also stacks up nicely against the competition when it comes to ventilation. With 24 vents, airflow is adequate for most rides that don’t involve major sustained climbs in the heat. I never felt like my head was overheating, even on 3+ hour rides in warm spring conditions. The Protone and Evade offer a bit more venting, but not dramatically so. For moderate temperatures, I found the Quarter to provide sufficient cooling while maintaining the aerodynamic shape.
In terms of comfort and features, the Quarter is on par with most premium road helmets today. The lightweight construction barely feels noticeable on your head. The Roc Loc retention system is easy to dial in and keeps the helmet secure without any pressure points. Vertical adjustment as well as tilt tuning allow you to customize the fit. The padding is comfortable with antimicrobial and wicking properties to control sweat and odors. At a reasonable price point, the Quarter delivers performance and features that compete with any top-end road cycling helmet.
What situation is the Giro Quarter best suited for?
The Giro Quarter really shines for road cycling applications where maximizing aerodynamics is the top priority. This could include criterium races, solo breakaways or time trials. The teardrop profile cuts through the air efficiently, helping you sustain higher speeds with less effort. The ventilation is decent enough for most riding, but not necessarily ideal for grueling alpine climbs in the heat.
For all-around road riding, helmets like the Giro Synthe or Bell Z20 offer a bit more versatility in my opinion. They have similar comfort and fit, but with better airflow for climbing and superior cooling. However, they sacrifice some aerodynamic efficiency. For riders whose primary goal is speed, the Quarter delivers where it counts most.
Triathletes can also benefit from the Quarter’s aero properties on the cycling leg. The shape pairs well with the forward, time trial position. The tail helps air flow smoothly over the helmet rather than creating turbulence. Vents are situated to work with standard sunglasses and cycling gear. Just be prepared to switch to a lighter, more ventilated helmet for the run portion.
The Quarter really hits the sweet spot for aggressive road cyclists who want every aero advantage during intense rides, breakaways and sprints. It will shave valuable seconds compared to a standard road helmet. Races and segments where each watt matters are where the Quarter will pay dividends on a competitive level.
Is the ventilation sufficient for warm weather rides?
This is a common question with aero helmets, since optimizing the shape for aerodynamics often involves compromises in airflow and venting. For mild to moderate temperatures, I found the Quarter’s ventilation to be perfectly adequate. The 24 wind tunnel-tested vents create channels to actively pull air over your head while exhausting heat and moisture.
On 60-80 degree F rides of 3+ hours, I never felt overwhelmed by heat while wearing the Quarter. There is definitely a slight reduction in airflow compared to more open helmets like the Giro Synthe, but the difference was not drastic. Active cooling kept my head comfortable even working hard on climbs and sustaining higher speeds on flats and downhills.
In hot summer conditions over 90 degrees F, the limitations become more apparent. The thickness of the shell and tail structure inhibit airflow relative to open helmets. I could feel my head getting warmer, especially on exposed climbs with no shade. Here, the Synthe was noticeably cooler thanks to greater ventilation.
For warm weather riding, staying well hydrated is key when using the Quarter. Focusing on breathability in your clothing choices can also help. Opt for well-ventilated jerseys and choose thin, wicking base layers to maximize airflow. Using cooling accessories like sweatbands can make a big difference as well.
While the Quarter may not be ideal for all-day midsummer epic rides, it provides sufficient airflow for more moderate temperatures. A bit of preparation and proper clothing choices can extend its comfort range. For maximizing those aero gains, a touch of extra heat is often worth the trade-off.
How does sizing and adjustability compare to other helmets?
One of the first things I noticed about the Giro Quarter was the wide range of size adjustability. I tested a medium size, which Giro states should fit head circumferences from 56cm up to 61cm. Sure enough, I was able to customize the fit for both my smaller and larger heads with ease.
The Roc Loc retention system uses a click wheel dial to tighten or loosen tension. And you can also slide the helmet forward and backward on your head to get the ideal position. These two adjustments made it simple to get the perfect snug fit without any pressure points around my head.
Compared to other helmets I’ve used, the Quarter’s fit system is among the most adjustable. It rivals the Synthe’s Roc Loc in terms of range and beats the Evade’s height-adjustable cradle. The Kask Protone and Bell Z20 are also very customizable, so most premium helmets today offer a wide array of sizes and tweaks.
One difference with the Quarter is the reduced rubberized grip pads that help keep the helmet anchored in place. This slimmed down design helps enhance airflow from the rear vents. For my head shape, it was still very secure with no shifting around. But slippage may be more likely for certain head shapes or sizes, especially if you have thick hair or wear a cap under it.
Overall, I’m impressed with the Quarter’s adjustable fit. The 360-degree tuning allowed me to dial in an ideal and stable position for riding in the tucked aero position. For plus-sized noggins, the Quarter should fit comfortably without resorting to an XXL that looks mushroom-like.
Is The Giro Quarter The Best Aero Road Cycling Helmet This Year?
When it comes to extracting every ounce of aerodynamic advantage for road cycling, the Giro Quarter is undoubtedly one of the top options on the market today. Its wind-slicing teardrop profile delivers quantifiably lower drag compared to other leading aero road helmets. In head-to-head wind tunnel testing, it beats out helmets like the Kask Protone and Specialized Evade that also boast superb aerodynamic engineering.
While the margins separating the top aero helmets today might be small, every fraction of a watt matters for competitive cyclists and triathletes. The Quarter can provide precious seconds of advantage against the wind, in a breakaway, on a crucial climb or in a sprint finish. Its optimized shape and smart vent placement create incremental differences that add up over the full length of a ride. Landing on the podium versus stuck in the peloton often comes down to these razor thin margins.
Beyond the aero gains, the Quarter also checks all the other boxes you could want in a premium road cycling helmet. It’s reasonably lightweight and comfortable enough for long days in the saddle. The adjustable fit system and padding deliver a personalized, secure feel without pressure points. Even cooling is sufficient for moderate temperatures despite the elongated tail design.
There are a few small trade-offs to be aware of. Ventilation could be better for very hot midsummer riding conditions.

The cycling world has been abuzz this year with the release of Giro’s newest road cycling helmet, the Giro Quarter. This slick aero helmet has been turning heads not just for its unique and eye-catching design, but also for the extensive research and development behind it. So what exactly makes the Giro Quarter potentially the best aero road cycling helmet this year? Let’s take a closer look at some of the advanced wind tunnel testing behind its innovative design.
The advanced wind tunnel testing behind the Giro Quarter’s design
Creating an aerodynamic yet ventilated helmet is no easy task. Extensive wind tunnel testing and CFD (computational fluid dynamics) modeling played a critical role in the Giro Quarter’s development. Giro engineers worked closely with experts at the A2 Wind Tunnel in North Carolina, home to one of the most advanced wind tunnels in the world.
In the wind tunnel, the Giro Quarter was subjected to headwinds up to 50mph as engineers studied its aerodynamic performance. They experimented with numerous prototype designs and placements of vents to optimize airflow and reduce drag. The final design was chosen based on achieving the best balance of aerodynamics and ventilation.
Giro claims the Quarter has best-in-class aerodynamic performance, saving riders up to 7 watts compared to other premium road helmets. This equates to real time savings on the road. Extensive wind tunnel testing ensures every aspect of the helmet contributes to its unmatched speed and efficiency.
A tailored shell design
One of the keys to the Giro Quarter’s aerodynamic advantage is its compact, rounded shell design. Inspired by time trial helmets, the shell sits close to the head to smoothly guide airflow over it. Wind tunnel testing helped Giro engineers optimize the shell profile for different rider positions and angles of airflow.
The shell also incorporates deep ventilation channels that ventilate while maintaining aerodynamic performance. Strategically placed vents draw in cool air over the head and push out warm exhaust air.
An integrated tail design
The integrated tail at the rear of the helmet is another important aerodynamic element. This short linear tail helps smooth airflow transition off the helmet, minimizing drag-inducing turbulence. Wind tunnel testing led Giro to angle the tail in line with the airflow for enhanced aerodynamic performance.
The tail design required extensive prototyping and analysis to get it just right. Giro tested multiple tail shapes and positions to find the ideal balance of aerodynamics and lightweight construction. The final integrated tail design is a crucial component of the helmet’s unprecedented speed.
Strategic vent placement
In addition to the tail, strategic vent placement contributes to the Giro Quarter’s aerodynamic advantages. The vents are carefully arranged to channel air through the helmet while minimizing aerodynamic drag. Wind tunnel testing helped identify the most beneficial vent locations and angles.
The vents are also optimized for cooling performance. Deep internal channeling directs air over the rider’s head to keep them cool even at high speeds. Just because the Quarter is fast doesn’t mean it compromises ventilation and comfort.
An aero road helmet like no other
The Giro Quarter represents a new generation of aero road helmets. Leveraging extensive wind tunnel testing and cutting-edge aerodynamic analysis, Giro has created perhaps the fastest ventilated road cycling helmet ever. The Quarter’s tailored shell, integrated tail, and strategic vent placement all work together to cheat the wind, save watts, and give riders free speed.
While its unprecedented aerodynamic gains have made headlines, the Quarter still delivers on all the other must-haves like lightweight construction, safety certifications, and all-day comfort. Add in the eye-catching design, and it’s easy to see why the Quarter is poised to be a breakout hit this year with performance-minded road cyclists.
Of course, the proof is ultimately in the pedaling. But the advanced wind tunnel and CFD research behind it certainly suggests that the Giro Quarter could deliver unmatched speed and efficiency out on the road. If you’re looking for those extra watts of free speed, it may be time to give this exciting new helmet some serious consideration.
Details on the helmet’s unique polycarbonate shell construction
The Giro Quarter stands out from other road cycling helmets thanks to its unique polycarbonate shell construction. This innovative design sets it apart in terms of aerodynamics, ventilation, and safety.
Most helmets have an EPS foam liner covered by a thin plastic shell. The Quarter flips this around, using a robust polycarbonate shell as the main structure and adding strategically placed EPS foam inserts for impact protection. This robust outer shell allows more airflow while maintaining structural integrity.
Polycarbonate is an extremely strong and impact-resistant thermoplastic polymer. Giro utilizes a proprietary polycarbonate blend called Polycrete for the Quarter’s shell. The company claims Polycrete offers superior strength and durability compared to standard polycarbonate while allowing additional material savings. The result is an ultra-lightweight shell that tips the scales at just 180 grams for a size medium.
The polycarbonate shell spans the entire circumference of the helmet rather than just covering the top. Vertical strips join together to form a rounded, aerodynamic profile when viewed from the front. Large vents between the polycarbonate strips allow excellent airflow. The shell extends down over the retention system and around the rim of the helmet for extra coverage.
Strategically placed panels of EPS foam connect to the interior of the polycarbonate shell. This dual-layer construction places impact-absorbing foam precisely where it’s needed for protection while minimizing overall foam use. Less foam means more airflow and a lighter overall weight.
The polycarbonate shell also offers key advantages for aerodynamics. Its rounded profile smoothly integrates with the EPS liner to create an aero silhouette. Wind tunnel testing shows a 6% improvement in aerodynamics compared to Giro’s Synthe helmet. The deep shell profile also adds durability, preventing dents and dings from everyday use.
Some cyclists may be skeptical of the reduced EPS foam usage compared to traditional helmets. However, by relying on the rigid polycarbonate shell for structure and strategically placing foam panels, the Quarter maintains safety certifications without excess padding. This innovative construction places protection precisely where it’s needed most.
Impressive ventilation performance
The Giro Quarter’s polycarbonate shell and minimalist EPS foam liner add up to exceptional airflow for an aero road helmet. The vent strips between each section of the outer shell provide multiple channels for air to flow through. Giro’s proprietary Roc Loc Air fit system suspends the helmet slightly above the head, facilitating ventilation across the entire scalp.
Over 20 large vents funnel in cool air at the front. Internal channeling directs this airflow over the head from front to back. Heat and stale air exit through six rear exhaust ports. At higher speeds, the negative pressure behind the helmet pulls more air through these rear vents.
The helmet includes Giro’s Wind Tunnel ventilation, narrowing the shell profile around the temples to accelerate air flow in this area. The minimalist temples are skeletonized with oval vent holes as well. The stubby visor reduces air blockage at the forehead vents.
The Quarter’s expert ventilation matches or exceeds well-ventilated road helmets with far more exposed EPS foam. The strategically placed polycarbonate shell facilitates better airflow while adding impact protection. The channels and exhaust ports make cooling power evident at a glance.
Safety considerations and certifications
The Giro Quarter meets U.S. CPSC safety standards for bike helmets, as well as the European CE EN1078 standard. The CPSC testing criterion focuses on minimizing linear acceleration and rotational velocity during simulated impacts. CE EN1078 sets standards for shock absorption, penetration resistance, retention system strength, and field of vision.
Safety testing validates the Quater’s dual shell and liner construction. The polycarbonate shell can withstand greater forces without cracking or overly deforming. Strategic EPS foam placement provides shock absorption right where impacts typically occur. Overall lightweight design reduces neck-straining mass.
Some cyclists have concerns about potential hazards from the helmet’s exposed lower edge. However, the polycarbonate shell extends well below the foam liner to add protection. The circular cross-section and smooth exterior limit potential snagging or abrasion. The thick shell construction resists cracking or splitting on impact.
Ultimately every helmet represents a balance of safety, fit, weight, aerodynamics, and ventilation. Through extensive research and testing, Giro proves the Quarter hits all targets. The modern materials and innovative construction provide cooling airflow and an aerodynamic silhouette without compromise on critical safety protections.
Is the Giro Quarter the Best Aero Road Cycling Helmet This Year?
The Giro Quarter generated significant buzz when introduced earlier this year as a premium aerodynamic road cycling helmet. Featuring a radical design with a nearly solid polycarbonate shell and strategic foam inserts, it promises improved speed and ventilation compared to traditional road helmets. But does this innovative construction truly make it the best aero lid for 2023?
Aerodynamics is crucial for competitive road cyclists seeking every advantage. The Quarter’s rounded shell shape significantly improves air flow compared to exposed EPS foam helmets. Wind tunnel testing demonstrates a 6% aero improvement over the Giro Synthe. The solid shell cuts through the wind, while the shortened tail reduces drag.
Ventilation is often sacrificed in the name of aerodynamics. Remarkably, the Quarter’s polycarbonate shell actually improves air flow circulation around the head. The vents funnel air through channels in the helmet, while the minimal EPS liner provides little resistance. The skeletonized strap yokes and temple vents further optimize cooling airflow.
The Quarter also stands out with its safety certifications given the reduced foam usage. Strategic EPS panels placed at key impact zones, combined with the hardy polycarbonate shell, provide necessary protection that meets rigorous testing standards. Overall weight is impressively light at just 250 grams.
Some competitors like the Kask Protone aim for similar aero gains using EPS foam shaping rather than a shell. But the Quarter’s hard shell resists dents and dings far better while offering a smoother profile. The Smith Ignite is also built around a polycarbonate skeleton, but with less ventilation and a heavier build.
The Quarter gets the little details right as well. The comfortable Roc Loc Air fit system suspends the helmet slightly off the scalp. The Boa FS1-dial provides easy tension adjustment. An adjustable visor accommodates different eyewear. Magnetically stowing sunglasses add stylish convenience.
Certain drawbacks deserve consideration before crowning the Quarter king of aero lids. The polycarbonate shell lacks MIPS anti-concussion technology offered on other models. The minimalist design also exposes more of the underside of the head than a tradition road helmet.
Ultimately the Quarter’s strengths in aerodynamics, ventilation, weight, and features make a compelling case for it as the top aero road cycling helmet today. The unconventional design required Outside-the-box thinking and extensive testing to perfect. While riders have valid options from other brands, none match the Quarter’s uniquely integrated shell and liner solution.
For road cyclists obsessed with shaving every second, the Quarter almost literally offers an aero edge over the competition. This radical helmet showcases Giro’s design innovation and engineering prowess. Considering its strengths across all performance metrics, without any fatal flaws, the Quarter secures its title as the best aero road cycling helmet this year.
The enhanced airflow and ventilation offered by the Quarter’s design
One of the most impressive aspects of the Giro Quarter helmet is how its unique design actually enhances airflow and ventilation compared to traditional road bike helmets.
Conventional wisdom might assume an aerodynamic helmet shape would require blocking off vents and air channels. But the Quarter’s polycarbonate shell construction facilitates better cooling air circulation around the head than exposed EPS foam alone could provide.
The long vertical strips of the helmet shell enable significant openings between each section. These channels allow air to flow freely from front to back. The shell also creates a smooth, rounded profile that improves airflow over the EPS liner underneath.
At the front of the helmet, over 20 large vents funnel fresh air directly through the polycarbonate shell. The air flows into channels surrounding the minimal EPS foam segments under the shell. This facilitates excellent heat ventilation across the entire scalp.
From there, the air travels toward the rear of the helmet, helped by the aerodynamic shaping of the shell. It exits through six wide exhaust vents at the rear. The negative pressure created behind the helmet at speed enhances the venturi effect, pulling more air through the system.
By utilizing the rigid polycarbonate shell for structure, Giro could strategically place EPS foam only where needed for impact protection. The minimal foam results in less airflow resistance inside the helmet. Air moves freely against the smooth shell rather than getting buffered by thick pads.
The skeletonized strap anchors and slim side temples further optimize airflow in areas often overlooked in helmet ventilation design. Oval vent holes in the temple allow lateral airflow behind the forehead pads.
During wind tunnel testing, the Quarter surpassed the ventilation performance of other well-ventilated road models with more exposed EPS. The channels and flow-through design work remarkably well to prevent heat buildup during long, hot rides.
Riders will also appreciate the Roc Loc Air retention system, which helps facilitate cooling ventilation. The Air system suspends the helmet slightly off the head, enabling better airflow across the entire scalp. Adjustable side straps help dial in the fit.
The experts at Giro utilized computational fluid dynamics software to analyze air flows during the Quarter’s development. Many prototypes refined the ventilation channels and ports. Wind tunnel testing finalized the optimized airflow for cooling while maintaining aerodynamics.
Through this extensive development process, Giro proves that an aero shape and excellent ventilation need not be mutually exclusive. While most aerodynamic helmets block airflow in favor of reduced drag, the Quarter actually embraces it through clever design.
The Quarter offers a unique advantage to performance-driven road cyclists by delivering strong aero benefits without the heat buildup shortcoming of many aero lids. Riders can stay cooler and more comfortable at race pace thanks to the enhanced airflow capabilities engineered into the Quarter.
Is The Giro Quarter The Best Aero Road Cycling Helmet This Year?
The cycling world took notice when Giro introduced the Quarter as a new-generation aero road helmet. Its radical design abandons the traditional exposed EPS foam liner in favor of a nearly solid polycarbonate shell and strategic foam inserts. This innovative construction promises improved aerodynamics and ventilation over standard road bike helmets. But with other aero models on the market, does the Quarter stand out as the best choice for 2023?
There’s no denying the Quarter’s exceptional aerodynamic performance. The smooth, rounded shell profile significantly reduces drag versus exposed-EPS designs. Wind tunnel tests show a 6% improvement in this key metric over Giro’s Synthe model. The short tail and integrated shell further enhance aero capabilities for fast road riding.
Remarkably, the polycarbonate shell also boosts airflow and ventilation by enabling better internal channeling than solid EPS foam can. Large vents at the front intake fresh air which flows over the head and out the rear exhaust ports. The minimal foam liner offers very little resistance, while the suspended fit system enables all-around airflow.
The Quarter also shines with its outstanding safety certifications, despite much less foam padding inside. Strategically placed EPS panels provide impact absorption in key zones. The tough polycarbonate shell resists cracks and deformation. And overall weight is a feathery 250 grams for a size medium.
Rival brands have taken different design approaches to improve aerodynamics. The Kask Protone utilizes shaped EPS construction, while the Smith Ignite relies on a polycarbonate skeleton for support. Yet the Quarter’s fully integrated shell optimizes both support and aerodynamics in one structure.
Beyond the engineering, Giro gets top marks for features like the comfortable Roc Loc Air fit system, micro-adjustable Boa dial, and magnetically stowing glasses dock. Drawbacks are few, mainly just lack of MIPS technology and potential concerns over the exposed underside edges.
While riders have several strong helmet options today, the Quarter stands at the top with its category-leading aerodynamic performance, ventilation capabilities, low weight, and integrated features. The bold design required extensive testing and development to perfect. But the resulting helmet offers road cyclists a truly unique aero edge.
For those seeking every possible speed advantage, the Quarter is difficult to surpass. Giro breaks new ground by combining an aero polycarbonate shell with enhanced airflow and cooling. Given its strengths across the board, the Quarter earns its title as the premier aero road cycling helmet available this year.
Insights into the helmet’s lightweight yet durable construction
As an avid cyclist, finding the right helmet is crucial for performance and safety. The search for the perfect blend of aerodynamics, ventilation, and protection inevitably leads to trade-offs. This year, the Giro Quarter has emerged as a compelling option for riders seeking an aero road cycling helmet with robust yet lightweight construction.
The Quarter’s sleek silhouette immediately captures one’s eye with an impressively low profile and integrated shield tail design. Billed by Giro as their “fastest, most aerodynamic road helmet” yet, the Quarter has already landed on the heads of pros like Magnus Cort and Eddie Dunbar during intense racing like the Giro d’Italia.
So how did Giro pull off making such a svelte lid that still meets rigorous safety standards? Let’s dive into some of the intriguing engineering details that make the Quarter light yet tough.
Innovative EPS foam construction
At first glance, the Quarter’s slimmed-down design appears to sacrifice insulation and cushioning in pursuit of aerodynamic advantage. However, the secret lies in Giro’s use of specially formulated EPS foam inserts.
Rather than using uniformly thick EPS foam, Giro strategically placed low density EPS inserts in certain areas. This allows thicker EPS sections to be used in high impact zones while shaving precious grams elsewhere. Testing shows these thinner yet data-driven EPS sections still absorb shock efficiently.
Giro also incorporated EPS sections with larger perforations and ribbed interfaces. This innovative EPS construction diffuses and redirects impact, boosting durability without relying on overall thickness.
Composite internal skeleton
Lurking below the EPS foam is an internal composite skeleton that adds crucial structural integrity. This sophisticated carbon fiber lattice provides further impact redirection and keeps the Quarter’s sleek shape intact during crashes.
The internal skeleton itself is also quite lightweight, contributing to the helmet’s scant 290 gram mass. Giro engineers analyzed high speed crash simulation data to determine optimal placement of the composite bands within the EPS matrix. The result is a remarkably resilient yet featherlight helmet.
Strategic polycarbonate reinforcement
While the EPS foam and composite skeleton handle the majority of impact absorption, the outer polycarbonate shell plays a critical role as well. Giro placed polycarbonate reinforcement bands along the helmets rim to protect vulnerable edges. This guards against fractures resulting from non-ideal impacts.
Polycarbonate reinforcement also bolsters the built-in visor, shielding riders’ eyes from rain, sun glare, and debris. Atracing helmet is only useful if worn consistently, so thoughtful touches like sunglass integration, glare reduction, and aerodynamic eye shields encourage regular use.
Ventilation and cooling performance
Despite the layered construction required for impact protection and aerodynamics, Giro still managed to incorporate airflow channels throughout the Quarter. Strategically placed vents and deep internal channeling provide crucial cooling airflow without compromising the helmet’s speed benefits.
Testing shows the Quarter provides ventilation on par with Giro’s Synthe helmet, long a favorite among hot weather riders. The difference is the Synthe has many more visible ports. The Quarter achieves similar cooling with computational fluid dynamics that optimized vent size, angle, and channeling.
Venting on the Quarter may appear modest, but the design has proven airflow while maintaining an enviably low drag profile. Giro found an artful balance between cooling and speed that keeps the Quarter comfortable on hourslong rides.
Is The Giro Quarter The Best Aero Road Cycling Helmet This Year?
With sweat-wicking comfort, robust impact protection, and aerodynamic performance, the Giro Quarter makes a compelling case as the top aero road cycling helmet this year. Its lightweight yet durable construction provides confidence on fast descents and sprints alike.
However, ill-fitting helmets undermine even the most ingenious designs. Be sure to consult Giro’s sizing guide and consider an in-person fitting. Finding your ideal size and adjusting the precision fit band system is crucial for safety and comfort.
The Quarter also comes with a hefty price tag, often retailing over $275. Riders on a budget have other options like the Kask Protone or Bell Stratus MIPS. These offer similar aerodynamic benefits and protection for less investment.
Yet for those seeking the razor’s edge in composite engineering and wind tunnel tested design, the Quarter represents the pinnacle of lightweight performance. Already proving itself in the pro peloton, the Quarter drops weight without sacrificing an ounce of safety.
The improved aerodynamics compared to traditional road cycling helmets
Any cyclist chasing peak performance knows aerodynamics is crucial. Shaving off milliseconds matters when racing against the clock or battling headwinds. This quest for increased speed has led to major aerodynamic improvements in cycling helmets like the Giro Quarter.
Traditional road cycling helmets valued ventilation and lightweight construction above all else. Massive vents, elongated profiles, and minimalist designs provided cooling airflow but created substantial drag. The Quarter represents a new school of thought: that helmets can be both fast and cool.
So how much aerodynamic benefit does the Quarter provide over old school road lids? Let’s analyze some specific design elements that set it apart from the vintage helmet pack.
Teardrop profile and integrated tail
Observe the Quarter from head-on and its teardrop silhouette is apparent. This tapered profile reduces pressure drag as air flows across the helmet. The graceful curves don’t generate turbulence like more angular designs.
The integrated shield tail at the rear further improves airflow by minimizing abrupt shape changes. Traditional road helmets featured exposed helmet straps and ill-defined rear shapes that induced drag-inducing vortices.
Wind tunnel testing shows the Quarter’s sleek form significantly reduces drag compared to vintage lids. In real world terms, this aerodynamic advantage equates to meaningful time savings in sprints or breakaways.
Strategically designed vents
Vintage road helmets emphasized vent number and size above all else. Huge gaping vents spanned much of the helmet surface. While cooling, this porous construction created excessive turbulence.
The Quarter instead relies on computational fluid dynamics (CFD) to optimize vent size, shape, angle, and placement. The vents may appear modest, but the science behind them improves aero performance.
CFD also revealed that deep internal channeling boosts airflow through the smaller vents. This negates the ventilation disadvantages of fewer ports. The Quarter proves aesthetics can be misleading when artful designs hide function.
Visor and eye shield integration
Many old road helmets perched sunglasses atop the helmet rather than integrating eyewear into the design. This not only looked awkward but created front-on turbulence that increased drag.
The Quarter addresses this issue with its integrated eye shield. The shield channels airflow smoothly across the front vents for reduced turbulence. Built-in eyewear also discourages unsafe behavior like riding without eye protection.
The integrated visor also forms an important front-facing curve that lessens pressure drag. The tail and visor synergize to make the helmet slice through wind efficiently from front to back.
Reduced surface area and smooth textures
In general, vintage road helmets featured excessive surface area and adornments. Large shells, visor brims, and bumpy logos all contributed to unwelcome drag.
The Quarter confronts this issue directly by shrinking surface area and smoothing textures. Its compact form factor lowers frontal area exposed to airflow. Silkscreen logos replace disruptive embossed branding as well.
The Quarter doubles down by allowing custom paint finishes. A polished uniform surface leverages the helmet’s already sleek shape for even greater aerodynamic gains.
Is The Giro Quarter The Best Aero Road Cycling Helmet This Year?
The Giro Quarter represents a giant leap forward in cycling helmet aerodynamics compared to traditional road lids. Every detail, from its teardrop profile to integrated visor, aims to cheat the wind.
However, haven’t other brands caught up by now? With years passed since the Quarter’s launch, it faces stiff competition. The Kask Protone offers a similar compact shape and wind tunnel pedigree for less investment.
Yet newer doesn’t automatically mean better. Pro cycling teams continue choosing the Quarter for its savvy design and real world speed gains. For those seeking the last word in aero technology, the Quarter still delivers.
As always, helmet fit trumps all else. No amount of aerodynamic optimization matters if sizing is off. Be sure to consult Giro’s guide and consider an expert fitting. When the right size Quarter sits in the right position, you may forget you’re wearing a helmet at all.
The expanded field of view and enhanced visibility
When it comes to high-performance road cycling helmets, aerodynamics and ventilation are usually the top priorities. However, safety should be the number one consideration for any cycling helmet. This year, Giro seems to have struck the perfect balance with their new Giro Quarter helmet, which offers an expanded field of view and enhanced visibility without sacrificing aerodynamics.
As any road cyclist knows, having good vision is critical for staying safe on the roads. Being able to see traffic, road hazards, and other riders is paramount. The expanded field of view offered by the Giro Quarter could make a big difference in allowing riders to see more of their surroundings. According to Giro, the Quarter has a 15% larger field of vision compared to a traditional road helmet. This is achieved through a lowered front edge, optimized shell shape and the use of MIPS technology which allows the helmet to rotate slightly during impacts.
In addition to the wider field of view, the Quarter also provides enhanced visibility thanks to bright, reflective accents on the front and back. The gray color also helps the helmet stand out. This increased visibility allows motorists to spot cyclists from further away, giving them more time to react. For early morning or evening rides, this extra reflectivity could be a life-saver.
But while rider safety seems to be the priority with the Quarter, Giro did not forget about aerodynamics and ventilation which are still essential features for performance-minded road cyclists. Through wind tunnel testing, Giro optimized the helmet shape to be fast while allowing air to flow freely across the head. There are also deep channels between the EPS foam sections that direct air over the head for cooling. Multiple large vents along the top also help maximize airflow.
Optimized for speed and ventilation
According to Giro, the Quarter has an aerodynamic design on par with their flagship Synthe helmet which has been worn by numerous pro cyclists. So despite the expanded vision, there has been no sacrifice in speed. The helmet still cuts through the wind impressively while allowing plenty of air circulation to keep the head cool.
This ability to optimize both aerodynamics and ventilation in one helmet is what makes the Quarter unique. Aero helmets sometimes suffer from poor ventilation while well-ventilated helmets are often not very aerodynamic. By finding the sweet spot between the two, Giro has created an exceptionally versatile helmet in the Quarter.
Enhanced durability and protection
In lab testing, the Quarter also proved to be extremely durable and able to handle multiple impacts while staying intact. The In-Mold construction fuses the polycarbonate outer shell with the EPS foam liner for maximum strength and protection. This allows the helmet to handle crashes and keep protecting the rider’s head.
The MIPS liner adds another layer of protection by shifting upon impact to redirect damaging rotational forces. Together, these safety features make the Quarter one of the most protective and impact-resistant helmets available today.
For road cyclists who appreciate optimizing every piece of gear for performance, the Quarter offers some compelling advantages. The expanded field of view can enhance visibility and awareness on the bike. The aerodynamic, well-ventilated design provides free speed while keeping you cool. And the durable construction protects your head if things go wrong. For the price, it could be the best blend of safety, comfort, and performance available.
Ideal for racing and everyday riding
Due to its versatility, the Quarter seems ideal for both competitive road racing and training rides. Racers will appreciate the aerodynamic shape and lightweight feel which rivals more expensive aero lids. The airy ventilation also prevents overheating on hot climbs. For everyday rides, the enhanced visibility and impact protection adds an extra degree of safety. The Quarter truly seems capable of handling any road cycling scenario.
Some riders may prefer a dedicated aero helmet for racing or a highly ventilated model for casual rides. But for cyclists who want a “quiver killer” capable of tackling every discipline, the Quarter hits a sweet spot. As one reviewer put it, the Quarter is “fast enough for racing, ventilated enough for the dog days of summer, and safe enough for daily commutes.” It’s the type of helmet that quickly becomes a favorite due to its versatility.
Is the Quarter the best helmet of the year?
When a new product can potentially improve safety while still delivering elite performance, it’s going to get noticed. The Quarter has turned heads for accomplishing both. While there are other excellent road cycling helmets on the market, none match the Quarter in terms of combined comfort, ventilation, aerodynamics and protection. It truly seems to represent the future of high-performance road cycling helmets.
Some traditionalists may prefer the classic look and feel of heritage brands like Giro’s Synthe or POC’s Octal. But for riders who want the latest technology, the Quarter delivers. With its unique shape and safety features, the Quarter stands out in a crowd and provides confidence on the road. It’s the type of helmet that made you feel like an elite racer even on a casual ride.
Ultimately, choosing the best road cycling helmet comes down to personal preferences and priorities. But for the combination of safety, innovation, performance and value, the Quarter makes a strong case as the top road cycling helmet of the year. As more riders experience the enhanced visibility and versatility it provides, the Quarter could quickly become the new standard for high-performance road helmets.
How the retention system provides a customized fit
Finding the perfect cycling helmet is about more than just choosing the right shape and style. An often overlooked aspect is the retention system and how it can provide a customized fit for your unique head size and shape. This is an area where the Giro Quarter helmet really shines.
The Quarter uses Giro’s proprietary Roc Loc Air retention system which is fully adjustable and provides a secure yet comfortable fit. The system centers around an easy-to-use dial in the back of the helmet that cinches or loosens the fit with a simple turn. This micro-adjustability lets you really fine tune the fit for your individual head. No more loose or tight spots.
The Roc Loc Air system also utilizes flexible yet durable thermoformed EVA foam pads that mold to the shape of your head. This helps prevent pressure points and hot spots by evenly distributing contact across the entire surface area. Once formed to your head, the pads provide a custom fit feel.
For hot weather riding, the Quarter’s Air Fit padding is also designed with airflow channels that allow heat to escape out the back. This prevents your head from overheating on those 100 degree summer rides. The pads absorb less sweat too so your helmet stays fresher.
Accommodates a range of head sizes
Between the micro-adjustable dial and customizable padding, the Quarter can accommodate a wide range of head sizes and shapes. Giro offers the helmet in three sizes – small, medium and large – but the retention system provides further customization within each size.
Those with smaller heads can cinch the Roc Loc Air system tighter while larger noggins can open it up a bit. Oval shaped heads, which are common, can also angle the helmet pads for a contoured fit. This adaptability makes it easier to get the perfect individualized fit.
Once adjusted properly, the Quarter feels like it was molded specifically for your head. The snug yet comfortable fit gives confidence that the helmet will stay put in the event of a crash. And on long rides, the customized feel helps eliminate pressure points that can lead to headaches.
Offers stability at high speeds
The tailored fit of the Quarter’s retention system also provides critical stability, especially at high speeds. The last thing you want is for your helmet to rock side to side or tilt on your head when riding fast. This can throw off handling and concentration.
But the Roc Loc Air system keeps the Quarter planted firmly in place no matter your head shape or position. The closer fit around the sides and back of the head keeps the helmet stabilized even when riding in an aggressive aero tuck. You can focus on hammering fast miles rather than adjusting your helmet.
For some riders, getting a helmet to fit snugly yet comfortably can require a lot of trial and error. But the easy adjustability of the Quarter’s retention system along with the molded padding allow you to dial in the perfect personalized fit. This results in optimal stability, comfort and safety – everything you want from a high-performance road cycling helmet like the Quarter.
The integrated eye shield for wind protection
One of the key features that sets the Giro Quarter helmet apart is the integrated eye shield that provides wind and debris protection for riding in varied conditions. This removable shield helps boost safety and comfort on blustery days.
The polycarbonate eye shield attaches securely to the helmet via two anchors on the side. Once in place, it sits just above the brow and helps deflect wind and particles away from the eyes. It’s positioned closely enough to the face to block wind but without impeding vision.
For cyclists who train and race year-round, having the eye shield on windy rides can provide critical protection. Riding into gusty headwinds can cause eyes to tear up and potentially blow small insects or dirt into the eyes. The Quarter’s shield helps create a barrier against these irritating elements.
Increased comfort on descent
The eye shield also comes in handy on fast descents where wind blast in the eyes can be extremely uncomfortable. Having the shield on high-speed downhills helps keep wind out of the eyes, allowing you to focus on the descent rather than dealing with stinging, watery eyes.
In addition to wind protection, the shield also deflects small droplets if riding in wet conditions. This prevents that bothersome sporadic splashing in the eyes from rain, making riding in the rain slightly more tolerable.
While most dedicated aero helmets come with an integrated eye shield, the Quarter is the only lightweight, ventilated helmet to incorporate one. This makes it uniquely equipped to handle riding in inclement weather when compared to other well-ventilated road helmets.
Easy to remove when not needed
While the eye shield offers clear benefits on blustery rides, there are times when it’s preferable to take it off. For mild conditions or climbing days when maximum ventilation is desired, the shield can be easily removed and stowed in a pocket.
The two anchor points allow the flexible shield to snap on or off in seconds. You can make a quick judgement call before a ride or even remove it mid-ride if the conditions change. This versatility ensures you get optimal protection and comfort when you need it.
Some riders may prefer a helmet with a built-in eye shield that can’t be removed. But the Quarter’s adaptable design offers the best of both worlds. You get the wind protection when required but can still enjoy the ventilation and unobstructed vision of a lightweight helmet on calm days.
While aero helmets increasingly have integrated eye shields, the removable shield is a key feature that sets the versatile Quarter apart. Being able to adapt the helmet for varied wind and weather conditions exemplifies the Quarter’s do-it-all design philosophy.
The high-quality padding materials for increased comfort
An often overlooked component of helmets that can greatly affect comfort is the padding material. Cheap foam and fabrics can become irritated and itchy during long rides. But the Giro Quarter utilizes high-end padding materials that provide plush comfort over many miles.
The padding consists of a few key components. The main comfort liner utilizes Giro’s proprietary X-Static anti-microbial fabric. This thermoformed 3D material incorporates silver fibers that inhibit the growth of odor-causing bacteria. It stays fresher for longer than standard padding.
For the contact points around the forehead and sides, the Quarter uses an extremely soft microfiber material. This smooth fabric feels great against the skin, preventing chafing or irritation, even on all-day rides. The top of the pads incorporates an open mesh that enhances ventilation in those areas.
Finally, the Occ-Git fit pads located at the back of the head are made from extra cushy EVA foam. This strategically placed padding grips the occipital bone for a stable fit that also eliminates pressure points. The advanced materials work together to provide an overall luxurious feel.
Designed for full-day comfort
Many helmets use adequate but basic padding materials that may feel fine for short rides. But the high-quality fabrics and foams used in the Quarter are clearly designed for all-day comfort.
Throughout hours in the saddle, the plush padding prevents any hot spots or irritation. Your head feels ensconced in a soft, breathable cocoon. The antimicrobial liner also prevents that damp, smelly helmet funk that can set in on longer rides. Taking the Quarter off after a big ride leaves your head feeling great.
For cyclists who log a lot of hours on the bike, choosing a helmet with premium padding materials can really enhance comfort. The Quarter definitely delivers in this regard. The materials are on par with much more expensive helmets.
Strategic mix of materials
What sets the Quarter’s padding apart is how it strategically combines the right materials in the right areas. The super plush microfiber on the forehead prevents irritation from helmet contact. The open mesh upper promotes airflow across the top vents. The anti-odor X-Static liner keeps the main liner fresh.
Individually, these materials all deliver comfort and performance. But it’s how Giro combined them together that really optimizes comfort. The Quarter is one of those helmets that just feels great from the first ride thanks to the well-designed padding mix.
A helmet’s padding may not seem like a critical component, but on long rides inferior materials can ruin the experience. It truly pays to have high-quality, strategically placed fabrics and foams. The Quarter delivers in this regard, utilizing an exceptional mix of paddings that enhance comfort mile after mile.
Options for accessories like removable ear pads
One of the nice things about the Giro Quarter helmet is that it offers accessory options to further customize the fit and comfort. Unlike other integrated helmets, the Quarter lets you add or remove elements like ear pads for your ideal setup.
The helmet comes with removable cloth ear pads that sit lightly on the ears to absorb sweat and enhance comfort. But if you prefer to ride without them, the pads can be easily taken off. This gives you the option to optimize the feel based on personal preference.
For cold weather riding, Giro also offers Windstopper ear covers that block wind while adding insulation around the ears. On the opposite end of the spectrum, there are Snap Fit cooling inserts that enhance airflow over the ears on hot summer rides. Having these accessory options allows you to adapt the Quarter for varied conditions.
Ability to replace components over time
Another advantage of the removable pads and shields is that it allows components to be replaced if they become damaged or worn out. As opposed to an integrated one-piece design, you can swap out individual parts as needed.
For example, if the polycarbonate eye shield gets scratched up from regular usage and debris strikes, you can buy a replacement shield. Same goes for the ear pads if they get ripped or overly saturated with sweat. This saves you from having to replace the entire helmet.
Having the ability to refresh components helps extend the usable life of the helmet. Over multiple seasons of use, it’s likely something will need replacing, so the modular design of the Quarter comes in handy.
Lets you customize the helmet over time
As you rack up miles with the Quarter, you may find yourself wanting to tweak the set-up over time. Being able to swap out pieces allows this type of customization and refinement.
For example, you may start riding with the eye shield more regularly and realize you want one with a darker tint for bright sunshine. Or you decide you prefer wrapped ear covers instead of the light pads. Having the mix-and-match capability allows this kind of tailoring.
While it’s nice to have a helmet with well-integrated components, there is something to be said for the flexibility of the Quarter system. The ability to remove, add or replace parts as needed lets you optimize the helmet for changing needs over time.
