Aero cycling helmets: how to choose the right shape

The purpose of the long tail is to maintain airflow from a distance. Moreover, it guides the airflow smoothly onto your torso. The short tail design provides you more freedom of movement.

The reason is that they are made to be competent if you rely on your torso. The less extreme position is applied in the tri- compared to stubbies, trailing and time which are more fitting.

For a long time, the manufacturers are trying to make slim shapes having minimal frontal area. Their aim is that the helmet will hit less air.

But now some brands are making a wider shape to add to the users’ shoulders. It depends on a lower position so that the torso and the helmet work at the same time.

Surface characteristics like trips ( Lazer)  and dimples (Louis Garneau) are made to promote laminar air flow. Here the air follows the size of a helmet. Other (POC) move for the smoothest probable surface.

You need to keep in mind that helmet makes parts of the bigger system. The rest of it remains in an aero riding physiology and position what you must give more importance. The best way is to book some wind tunnel time, where you may hone your position. You can use different helmets to evaluate it.

Wear a helmet in your home. Take photos from the back and front of the helmet. You can try it in your home. Just sat on a bike and examine everything very carefully. If you do it you will see the shape integrated neatly of not. You will also notice if a long tail is stuck up in the air causing drag.

Aero helmets for triathletes – how and why to use them

The motto of using a cycling helmet is to save your head from a serious accident. The aero savvy riders understand well that a covered head may be faster than a bare one through the air.

In Triathlon, lids designed for upgraded aerodynamics appeared first in the mid-80’s. It helped Scott Tinley to Hawaii to get a victory in 1985. In spite of thinking more about the benefit of this helmet, you may take the small handful of athletes.

The tipping position of aero helmet comes with Greg Lemond’s in 1989 Tour de France. You may demonstrate the necessity of aerodynamics by using Tri-bars and wearing a Giro Aerodynamics. You may do it through 58 seconds on Laurent Fignon over the last 25 km stage and wearing the yellow jersey. This is the starting point of the beginning of the aero arms race for the biking.

During the 90s aero helmets are greatly fairing to smooth airflow and give only a little protection for the rider’s head.

Gradually the tails of the helmet become longer and visors are included. The biggest change came in 2003 when UCI imposed a law that any helmet must be used for racing save the rider’s head. It means that aero lids have to incorporate huge extended polystyrene cores.

How and why to use an aero lid

All things are equal, a rider having aero helmet will be faster than a person wearing a normal standard bike helmet.

This is the view of aero expert that an aero helmet rider’s position would be worth 10 to 15 watts. Over the time of an Ironman bike, the leg would result within time measurable within minutes.

For such kind of inexpensive part of the kit, compared with a new bike or wheelset, an aero helmet is the best bang in term of aero gain for your back.

Though there are some caveats. The helmet must be well fit for the riders. The tail must be transition smoothly for the back of the riders, keeping small gaps as small as it can.

If that is not the problem, you need to move the head as a lot as you ride, the aero helmet slowing you down. It also requires long course triathletes whose head may be changed for fatigue and failing the attention of the bike legs.

Use lots of helmets, take the side of you wearing it to the turbo. But do not remember to test as you are fatigue as quick as you feel fresh.

Many athletes like to use an aero road helmet or a good stubbier tailed helmet like the Giro Air Attack which Leanda Cave like to wear to Kona glory in the year 2012, more versatile or better option.

The following factor is to consider the overheating. An aero helmet is always hot to ride in, and for an Ironman bike leg with the hot condition, overhearing may cost more than the helmet will save.

Keep in mind that Chrissie Wellington does not like to wear an aero helmet for Kona triumphs, and the bike splits are very shabby.

You are a triathlete; you need to consider transition. Stiff earflaps, fiddly visor, or tricky adjustment dial can simply cost you the chunk of time.

This type of thing does not matter for such a big deal for a long course race, but for Olympic distance event or sprint, these things need offset against the diminished aero time gains to the legs of the shorter bike.

Lastly, do not preserve your aero helmet for the race day. Like another race kit, this is for training that you are sure; the helmet is just for you.

Do you think the helmet is comfortable? Would you like to overheat it? These are the questions. You will be able to give answer all of these issues when you sometimes spend by wearing this helmet on the road.

If you have the full consciousness to wear an aero helmet, enter cycling time trials, only in one event, you may get funny looks for not using headgear which seems coming from the Battle of the Planets.

High-speed ventilation

The popularity of this helmet is growing fast, so people like to use full-blown TT lids. It is also critically important that the helmet gives more airflow to keep the head cool.

We have tested some helmet by wearing and measured their ability to move air around our heads at the time of traveling at cruising speed. Maybe 18 to 25 mph during faster mountain descents, in midday at hot Colorado sunshine.

Almost all helmets fared well and few downright surprising in how much air moves across the scalp. Other may be rough but not very much.

Low-speed ventilation

To move ahead with having hot air at the time of highest speed is an easy matter. But when going up the long or steep climb in humid summer day or hot day, we should carry cooling airflow, and hot air needs to be given off.

This is not surprising that most of the helmets fared poorly as it may be easier to make an aero helmet.

You have no account to airflow as well over and around the shell. This is the matter of the rider’s evaluation on different climbs with having speeds hovering around ten mph.


The truth is that the aero helmet is a good thing for increasing beauty as long as our perceptions are redesigned.

We will measure each of the helmet based on riding evaluation at various speeds at least hovering with ten mph.


The weight of the aero helmet is heavier than the other helmets on the market. The weight is more from forty to sixty grams. It is vivid to the end of 4 hours ride. Sometimes lighter may be better.

So, should I buy an aero helmet?

All Aero road helmets are heavier and a slightly less vented than usual helmets. The price of the helmets is bit higher. On the other hand, you may get a small reduction in drag. This is a marginal gain, but it makes an important dissimilarity as you like to go off the frontage and attempt your fortune in a race.

Final Verdict

Surely Aero helmet is the best helmet and faster choice for the users. It is not quite from free motion as lessen ventilation meaning you give vent to heat build up.

When we made a test of Giro Air Attack in 2013, reviewers said that I do not like to get on it as the arm warmer comes off. It is very warm.

If you do not live in cold climate, we would not suggest you buy the aero helmet as your first choice. For occasional Sunday suicide break, you may use an aero helmet.
