Bell Z20 Aero Road Bike Helmet

Bell Z20 Aero Road Bike Helmet
  • FUSION IN-MOLDING POLYCARBONATE SHELL, AERO-OPTIMIZED SHAPE, & PROGRESSIVE LAYERING CONSTRUCTION - A process pioneered by Bell bonds the helmet's outer shell to the EPS foam liner to create a sturdier helmet. The process of engineering a helmet liner with variable EPS foam densities to better manage the transfer of energies after some impacts.
  • FLOAT FIT RACE (INTEGRATED WITH MIPS) & MIPS-EQUIPPED - Custom fit at the highest performance, Seemlessly integrated with MIPS and offers three-way adjustability: height, pad width and tension. MIPS stands for Multi-directional Impact Protection System, which is a leading slip-plane technology inside the helmet designed to reduce rotational forces that can result from certain impacts.
  • X-STATIC AND XT2 PADDING & SWEAT GUIDE - Quick-drying materials, woven with real silver fibers. Sweat Guide pad design pulls moisture away from the brow pad and away from eyewear.
  • NO-TWIST TRI-GLIDES & PROGRESSIVE LAYERING - Quick-adjust fasteners that help keep straps flat and properly positioned. The process of engineering a helmet liner with variable EPS foam densities to better manage the transfer of energies after some impacts.
  • SPECIFICATIONS - Small (52-56 cm), Medium (55-59 cm), and Large (58-62 cm) Sizes. Important: always take a head measurement. Head sizes and shapes can vary, even within an age range. Using a helmet that does not fit can be dangerous; Overbrow Ventilation System with 10 vents.

Let’s kick things off with Bell’s sleek-looking Z20 Aero.

Bell took the aerodynamics of this model a step further than the traditional road helmets. You can expect a comfortable lid on your head with the additional benefits of MIPS technology.

Even though it has two layers of EPS, the overall construction is great and the helmet is surprisingly light.

And although it is on the higher end of the price spectrum, the helmet works great for round oval head shape.

You won’t have a hard time adjusting the dial ratchet system at the rear for a snug fit. And you get an even tensioning all around your head (unlike some helmets that only adjust the rear half of your head).

I like the Z20 Aero helmet, but it is not the best pick if you want something to protect your head during the warmer months.

Bell’s ventilation design for this otherwise awesome helmet is a bit lacking.

The good thing is that it fits most round heads and is very comfortable.

Overall, if you want a fantastic model to protect your noggin during the colder months, consider opting for Bell’s Z20 Aero model.

Pros

  • Great build quality
  • Custom fit with three-way adjustability
  • Sweat guides pull moisture from brow pad
  • Lightweight construction

Cons

  • Not enough ventilation

2. Troy Lee Designs A1 Mountain Bike HelmetBest Mountain Helmet for Round Head

Troy Lee Designs A1 Mountain Bike Helmet
  • Reinforced polycarbonate shell in-molded with the EPS liner extends down the sides and back of the head for maximum coverage and durability
  • Triple position adjustable retention system allows customized fit for various eyewear, head shape and riding styles
  • Single-piece, ultra-plush, removable and washable comfort liner made of moisture-wicking material for a dry, comfortable feel
  • 5-Star Rated by the VA Tech Testing Institute Bicycle Helmet Testing
  • Not intended for motorized use.

Here’s another model I’ll recommend if mountain biking is your thing.

The A1 bike helmet might not be the most expensive model in the world, but is one of the comfiest MTB helmets on the market. And that’s all thanks to Troy Lee Designs’ top-notch engineering.

You’ll hardly notice it on your head because it is incredibly light.

But don’t let the lightness fool you!

TLD built this fully encapsulated all-mountain helmet to offer maximum protection in all riding conditions.

Although it has good ventilation, you’ll enjoy this helmet more in cold weather.

Now, here’s the main reason I recommend TLD’s model for MTBers with Asian fit heads. It has a press-stud style height adjustment that allows you to get a snug fit for a rounder head.

Plus, the dial is reasonably precise.

My only gripe with TLD’s model is the chin strap.

For the price, the closure is a bit flimsy.

Apart from this, the A1 helmet offers an excellent fit for round heads. It’s a great pick if you are riding dirt jumps, charging single tracks, or grinding out miles on your favorite mounting bike.

Pros

  • Comfortable and lightweight
  • Visor doesn’t impede vision
  • Wide selection of colors
  • Includes a bag and stickers

Cons

  • Chinstrap is a bit flimsy

3. Bell Super DH Mountain Bike HelmetBest Full-Face Helmet for Round Head

Bell Super DH Mountain Bike Helmet

Bell Super DH Mountain Bike Helmet
  • MARKET-LEADING PROTECTION: Engineered in Giro’s category-leading helmet test lab
  • MIPS: Utilizes the Multi-Directional Impact Protection System to redirect energy in a crash
  • COMFORT: Easily adjust vertical position and tension with the Roc Loc 5 fit system
  • VENTILATION: 26 Wind Tunnel vents with internal channeling
  • LIGHTWEIGHT: In-molding construction

Want to take your mountain cycling experience to a whole new level? You’ll want to check out Bell’s Super DH model.

The convertible helmet is solidly built, incredibly comfy, and feels really great on the trail.

For the records, convertible helmets aren’t exactly new for Bell. But the Super DH is the manufacturer’s first model to be downhill-certified in full-face mode.

That means you can push yourself to the limits, speeding downhill without a single worry about your head, face, and chin.

Although it is a full-face helmet, you’ll get plenty of ventilation with Super HD. Even the wraparound chin bar has four vents!

It comes with nearly all the features you would expect in a top-rated bike helmet for a round oval head shape.

From an adjustable visor to a camera mount, a lot of vents, and sweat guide pads.

Of course, it integrates flex spherical MIPS technology to protect your noggin from both low-speed and high-speed impacts.

No doubt, the Super DH model is one of the best bike helmets for round heads.

But there’s a catch.

The model is anything but cheap. In fact, it is the most expensive option on my list. That’s not surprising considering that nearly all full-face downhill-rated bike helmets come with steep price tags.

Here’s the thing, though. It is worth every single cent!

I strongly recommend it if you can afford it, especially if you do a lot of downhill riding.

Pros

  • Super lightweight and comfortable
  • Interchangeable cushioning for best fit
  • Faceguard and removable wraparound chin bar
  • Adjustable visor with breakaway camera mount

Cons

  • Expensive model

4. Bontrager Starvos WaveCel Round Fit HelmetBest Adjustable Helmet for Round Head

B07VNTKWYV

Up next is Bontrager’s stylish road helmet.

This is by far the best bike helmet for Asian head I’ve come across in my many years of cycling.

Just to be clear, there’s no jab intended here.

In fact, studies show that people of Asian descent have a rounder head than their Western counterparts.

Okay, now that we’ve cleared the air, why should you consider Bontrager’s Starvos WaveCel Round Fit helmet?

First, Starvos has a wider design to deliver a better fit for anyone with a rounder head shape. Also, it comes in a wide range of sizes.

That means you’ll likely find an option that fits even if you have the largest head or you want something that fits your teen.

This versatile helmet is highly adjustable. To make things even easier, you can adjust the fit using only one hand.

There’s just one small downside with this Bontrager model.

You don’t want to be wearing it for long-distance rides in the warmer months. That’s because it doesn’t offer plenty of ventilation like some of the other models on this list.

But don’t worry.

The inner padding does an excellent job of wicking away moisture. And it is removable, so you can wash and keep it fresh after a long day of fun.

Pros

  • Available in extra small and extra large sizing
  • One-handed fit adjustment
  • Fully adjustable strap dividers
  • Soft, moisture wicking pads

Cons

  • Slighted restricted airflow

  • FUSION IN-MOLDING POLYCARBONATE SHELL, PROGRESSIVE LAYERING, AND EXPOSED POLYCARBONATE ROLL CAGE - A process pioneered by Bell bonds the helmet's outer shell to the EPS foam liner to create a sturdier helmet. The process of engineering a helmet liner with variable EPS foam densities to better manage the transfer of energies after some impacts.
  • MIPS-EQUIPPED AND FLOAT FIT RACE (INTEGRATED WITH MIPS) - MIPS stands for Multi-directional Impact Protection System, which is a leading slip-plane technology inside the helmet designed to reduce rotational forces that can result from certain impacts. Custom-fit at the highest performance, Seemlessly integrated with MIPS, and offers three-way adjustability: height, pad width, and tension.
  • X-STATIC AND XT2 PADDING, NO-TWIST TRI-GLIDES AND SWEAT GUIDE - Quick-drying materials, woven with real silver fibers. Quick-adjust fasteners that help keep straps flat and properly positioned. Sweat Guide pad design pulls moisture away from the brow pad and away from eyewear.
  • DUAL-FLOW VENTILATION, INTEGRATED BREAKAWAY CAMERA MOUNT, AND 4-POSITION ADJUSTABLE VISOR - Actively ushers cool air over the head and regulates temperature by drawing cool air into the intake ports and circulating it through a matrix of air channels. A seamless camera mount, requiring no zip ties or tape, is engineered to break away upon impact to reduce the risk of injury. Adjusts for maximum comfort and steeze. How many more positions you need bro?!
  • SPECIFICATIONS - Small (52-56 cm), Medium (55-59 cm), Large (58-62 cm), and X-Large (61-65 cm) Sizes (X-Large size comes in some colors). Important: always take a head measurement. Head sizes and shapes can vary, even within an age range. Using a helmet that does not fit can be dangerous; 26 Vents and 4 Brow ports.

This is one of my personal favorites.

Whether that’s because it has a stylish, eye-catching design is beside the point. Truth is, Bell’s Sixer is one of the most aerodynamic and comfortable helmets by a long shot!

A lot of thought went into designing this model. And it shows in how it comfortably holds your head inside the high-quality EPS foam that feels like a roll cage.

And yes, it has MIPS technology. So, maximum protection from rotational impact is nothing to worry about.

Here’s another good reason to love Sixer: It keeps your head cool, even when you cycle in hot weather.

That’s not too surprising considering the helmet has 26 vents and 4 brow ports!

And that’s not all.

It has a sweat guide pad designed to pull moisture away from your face. That means zero chance of getting all sweaty!

With this model, you get an adjustable visor, highly effective sweat guide, and MIPS integration.

Okay, enough of the bells and whistles.

Sixer is a bit expensive. So, why should you invest in it (besides looking cool on your bike)?

Bell built this helmet to fit just about any head size. More specifically, it can fit small round heads measuring 52 – 56 cm. It is also available for round heads as large as 61 – 65 cm.

Why is this one of the best bike helmets for round heads?

Simple: the float fit system makes all the difference. Besides delivering the right fit for a round oval head shape, it also allows easy vertical adjustment.

Pros

  • Integrated breakaway camera mount
  • Three-way adjustability
  • Sweat guide pulls sweat away from brow pad
  • 4-position adjustable visor

Cons

  • Pricey model

Giro proves that you can own a great helmet for under a hundred bucks.

Yes, you read that right!

Giro’s Fixture should be on your radar if you’re on a shoestring budget.

Although it is the most inexpensive option on this list, Fixture boasts of the MIPS technology available in higher-end helmet models. 

That means you’ve got better protection in case of crashes or bumps against trees and branches.

With 18 vents and an internal channeling design, there is hardly any chance of sweating under this helmet.

If anything you’re sure to remain cool even if you are a heavy sweater.

Fixture is fitted with a removable visor that protects your eyes from flares and bright lights. You can leave it on or take it off if you like.

Why is Giro’s Fixture an excellent pick for rounder heads?

It is designed to offer a universal fit sizing.

That means it is not just one of those bike helmets for round heads, it will also work for round oval head shape.

It will fit just about anyone on the first try!

And just in case you need to tweak things a bit, the Roc Loc fit system can be adjusted on the go using only one hand.

Pros

  • Affordable round head helmet
  • Highly breathable
  • Removable visor
  • Available in several colors

Cons

  • Visor tends to fall off sometimes

Buying Guide for the Best Bike Helmets for Round Heads

Most bike helmets made for the US market are too squared off inside. This makes them a bit uncomfortable for riders with rounder head shapes.

Before you hit the buy button on any helmet supposedly built for a round oval head shape, I’ll suggest you factor in the following.

More: Best Bike Helmet For Small Head

Measure Your Head

First things first! Measure your head. Never assume that all Asian fit or round fit helmets will work for you simply because you have a rounder head.

If your helmet is too big, it can come loose at the most ill-opportune moment.  If this ever happens, the helmet will not protect your head from injury.

Choosing the correct size helmet is the most important factor to consider when buying a lid for your noggin.

Figure Out Your Head Shape

Another important consideration is the exact shape of your head.

Head shapes vary quite a lot but most people have long-oval, intermediate, or round oval head shapes.

Most people have an intermediate head shape. This looks more like a squashed soccer ball when viewed from on top of the head.

You have a long oval head shape if your head looks like a wide football when viewed from on top.

And a round oval head shape is wider than average, making it resemble a soccer ball.

Figuring out your head shape will make things easy when it comes to finding the right helmet fit. You won’t have to endure pressure on your forehead or the sides of your head.

Helmet Style

Once you have your head measurement and figure out the shape of your head, it is time to choose a helmet style.

Personal preference comes into play here.

But you also have to think about the type of cycling you do.

The following are your options when it comes to bike helmet styles:

  • Road bike helmet: This is usually a lightweight helmet with lots of ventilation.

If you mostly ride on a road bike, consider getting a helmet that strikes a balance between ventilation and aerodynamics.

But you might have to shell out for this type of helmet.

  • Commuter bike helmet: In most cases, commuter bike helmets have a rounded shape, making them a great choice for people with rounder heads.

Many of these helmets come with a handful of useful features, including vents, visors, and even rear blinkers that increase visibility so that other road users can see you from a distance.

More: The Best Commuter Bike Helmet 

  • Mountain bike helmet: Most helmets for mountain biking come with a visor.

The feature protects riders from the ever-changing shades of off-road cycling.

It also protects against the environmental elements on the trail.

  • Full-face helmet: This is a mountain bike helmet that goes beyond the regular MTB helmets.

It is designed to protect the face and entire head.

Go for this type of helmet if you consider yourself a daredevil who enjoys pushing the limits!

  • Kids’ bike helmet: Whether your child has a round head or not, a kids’ helmet is a must-have if they must get on a bike.

Thankfully, extra small bike helmets are available for kids and teens, whether they ride a big kid bike or use a balance bike.

Try On the Helmet

Regardless of how things great a helmet looks online, it might be different in reality. For this reason, you want to try it on first.

But how do you try on a helmet when you’re buying online?

Any good online store will allow you to return a helmet if it doesn’t fit. That’s another way of saying you should make sure the online retailer has a good return policy before you make a purchase.

You want the helmet to fit snugly when you try it on. No pains, no pressure points, and no discomfort whatsoever!

Helmets are not the type of headgears you want to “settle for.” If it doesn’t fit perfectly, do yourself a favor and return it.

Of course, you should adjust the fit system first. Some helmets may not fit all heads right out of the box.

FAQ

What shape is my head for a helmet?

To know what shape your head is for a helmet, you’ll probably have to try it on.

A standard fit helmet (oval helmet) will make you feel tight pressure points at the sides of your head if you have a round-shaped head.

Also, the helmet might rock from back to front.

If you feel tight pressure points on your forehead, you have an oval head and the helmet will likely rock from side to side.

If you have a rounder head, your best bet would be to choose round fit helmets instead of opting for larger size standard fit helmets.

Should a bike helmet move on your head?

A bike helmet should fit snuggly but not too tight that it becomes uncomfortable. If it is too loose, it can fall forward and obstruct your vision.

Here’s a quick test to know whether or not your helmet is too loose.

Wear the helmet as you normally would and buckle it nice and tight. Now, push it from front to back and side to side.

If the helmet shifts up to one inch or more on your head, it is too loose and needs to be adjusted for a snug fit.

How do I know my helmet size?

The most accurate way to know your helmet size is to measure your head!

You don’t want to rely on head sizing for age ranges because specific sizes and shapes can vary widely even for people of the same age.

Thankfully, measuring your head is not rocket science, and here’s how to do it correctly to get the right helmet size.

Grab a tape measure and wrap it around your head. Start at your forehead, just above your eyebrow. Make sure the tape is above your ears.

You want to measure where a hat would normally sit on your head.

Once you have a measurement, write it down and use it to compare the sizing chart of any helmet you want to buy.

How do I know if my head is round or oval?

Finding out the shape of your head is pretty easy but it is not by merely looking at the shape of your face.

Instead, it involves looking at your head from the top – sort of a bird’s view.

But wait?

How can you view your head from the top?

Simple!

Ask a friend or family member to help you determine the shape of your head. Just make sure they can tell the difference between round and oval.

Flatten your head down and let the other person take a look at the top of your head.

If there’s no one to help you with this, grab your smartphone and take a selfie from above the top of your head.

Conclusion

I’m positive you’ve found a helmet on this list that works for your round oval head shape.

While Bell’s Sixer is my personal favorite, keep in mind that not all round heads are the same size.

Be sure to choose something that fits you perfectly.

Also, go for a model that has most of the features you want in a helmet. And by all means, pick something stylish like me.

You don’t want to look uncool in your bike helmet, do you?
