Wearing Bike Helmet

We love cyclists because it is fun and this activity is a great alternative for you to stay in shape without having to spend the time in a gym. What we can never forget while riding the bike is your helmet because this is a very important gear to help protect our head. Some people may argue that wearing a helmet won’t remove the risk or accident and it is true but it is still very necessary. The reason is because your helmet will help reduce the severity of the injury.

Bike helmets are very common and you can find them easily no matter where you live. The standardization on every place can be different however, based on how the regulator works in your place. The main reason why bike helmets are necessary is because they can provide more protection compared to when we are not wearing any lid. In fact, there are many other activities where you are required to wear a helmet such as in construction sites and in many other uncontrolled environments.

The way a bike helmet works is by covering our head, especially the front and top area. They are made of hard plastic which is usually polycarbonate on the outside and soft EPS foam on the inside. This polycarbonate shell is the one that will get in contact with any surface when you fall off the bike or meet a harsh surface while the foam is bridging the impact. This mechanism helps you to reduce the effect or impact.

Unlike what many may think, bike helmets are not rigid and they are designed to crack when receiving an impact. This is necessary to dissipate the energy so it is not fully transferred to our skull and this is also why it is wise to avoid wearing the same helmet if you have damaged them or if there is damage on the unit because this means the gear is not able to provide the ideal protection anymore.

When choosing for a bike helmet, look for the safety label in your option whether they meet the standard or not. This is to make sure that our helmet will work properly when needed and don’t forget to match the helmet size with your head. They are usually available in several sizes such as small, medium, and large and each company can have a different range for each size. There are also options with universal sizing, especially budget options but worry not because the inner sizing will still be adjustable.

About Giro Radix and Agilis

Wearing a bike helmet is very easy so we recommend always having it secured on our head while riding the bicycle. They are also affordable, depending on the model and brand that you like the most so everyone can have their ideal choice. They are not going to remove or make sure you are always safe but it is great to at least reduce the risk of a more severe head injury. If you think they often look weird, there are many styles to try.

Especially mountain bike helmets with visors which are going to look good on most people. Unlike typical road helmets, they are less round and this can improve our confidence as well. However, do note that MTB helmets are often heavier compared to the road version. As long as you are not riding on the more extreme side such as racing or downhill biking, both road and MTB helmets can be interchangeable but we have to make sure that they are made according to standard too.

Giro, as one of the most common options when it comes to bike helmets, is currently offering a wide range of helmets for cyclists whether you are commuter or downhill racer. Their helmets are also affordable based on the features and the type of helmet you prefer better. For those who want breezy and comfy helmets, Giro Radix and Agilis are two ideal options to consider. These helmets are already quite different but you can still wear them for the same discipline.

The Radix is an MTB helmet and the best thing about this type is their look because typically MTB helmets are very sporty. On the other hand Agilis is a road bike helmet but, unlike many other similar helmets, this one is a bit lower on your head. This way they are not going to create a bubbly look that is hated by many people. In comparison, both are very comfy and protective with some small differences.

Giro Radix and Agilis Design

When you put them side by side, the difference between Giro Radix and Agilis is very noticeable. As you can see, the Radix is very sporty. The overall shapes are very similar actually but due to the vents shape on Radix, it gives a more rugged and sporty accent to the helmet. On the other hand, probably because of the straight lines that are drawn from the front to the back of Agilis, this helmet looks rounder compared to Radix.

The weight is actually not far different because with a gap of around 16 grams for the CPSC rating, the two won’t feel much different when on the head. The styling is what separates the two prominently, making them look completely different based on what they are designed for. As for the available sizes, you can find a range of options but it seems Radix is also available in XL variant. Additionally, both are coming with matte paint which is great but the darker shades are very easy to stain especially if you ride on trails.

Giro Radix and Agilis Build Quality

Now for the most important part, let’s see what the Giro Radix and Agilis can offer starting from the build quality. They are passing or exceeding the same standard so we can be at ease when securing one on our head. We are also happy to see that both are properly covering the EPS foam which is often left uncovered in many other helmets. You can check the rim to see whether there is exposed foam since this may affect the lasting ability.


What’s just a bit different is probably thickness because Agilis is more even while Radix is noticeably thicker on the front while keeping the rear thinner. The inside of the helmets are almost identical aside of the vents as you get thin padding and adjustable fit. Just like most helmets both are also coming with MIPS ready to use. The Agilis is claimed with in-mold hardbody lower wrap which mentions the cover on the outer rim of the helmet, for higher durability.

Giro Radix and Agilis Fit System 

Next for the fit system, both Giro Radix and Agilis are using Roc Loc 5.5 or Roc Loc 5. These securing systems are very similar to many helmets and also most helmets in the Giro lineup. The comfort of Giro is always one of the greatest points of this brand and this fit is very comfy for a wide range of users. The headband of this fit is useful to cradle our head from the surface of the EPS liner inside to help manage air flow while providing a three dimensional adjustable coverage.

The chinstrap and clip are very standard but they work properly. It is adjustable with a rear anchor point so we can find the perfect side adjustment. Overall the two are very easy to wear for most people by providing a wide range of adjustability.

Giro Radix and Agilis Comfort 

Lastly for comfort, regardless of the terrain, you will always sweat while putting the effort making the bike go forward. The Giro Radix and Agilis are not the best cooling helmets ever but the vents work really well at reducing the heat and temperature from our head. Knowing humans lose heat from the head too, it is great to have a cooling helmet. In comparison, Agilis seems to be breezier in the same situation, probably due to the vents design but Radix is still very ideal for most people.

Giro Radix Vs Agilis

There are many good helmets from Giro but Giro Radix and Agilis are some of the best if you want an easy to wear lid, thanks to the fitting and overall quality. The two are on par with each other and still affordable, knowing how well they are made. In comparison we do think styling and ventilation are what set the two apart because Radix is sportier but the vents work better on Agilis.
