Giro Aerohead MIPS Helmet Review

In time trials, the competition is soaring high for speed and cyclists race against literal time to win the gold. To prepare for the win, cyclists need TT-gear that is efficient, fast and optimised for lean-forward riding.

Many bike helmets are either aero-focused or designed in a streamlined profile for speed but few have both.

Giro, a popular Swedish helmet company, recently launched the Aerohead MIPS helmet which has quickly amassed the eye of pro cyclists and become the best in the business for time trials. 

In this guide, we cover how the Giro Aerohead MIPS works so efficiently, what features it boasts and how it could be improved to perform better.

Giro Aerohead MIPS Helmet Features Review

The Aerohead MIPS bike helmet, not to be confused with the successor Giro Aerohead Ultimate MIPS, is famous for a lot of reasons other than its speed efficiency. Here’s the complete breakdown of the Aerohead’s features:

Shell Material and Safety

The Giro Aerohead MIPS bike helmet is made up of a tough polycarbonate shell that surrounds the totality of the helmet in a ‘unibody’ style to ensure no part of the head is exposed to impact forces.

Since it is generally targeted to time trialists and triathletes that are pedalling at an extraordinary speed, the safety of the helmet is especially focused on.

The Giro Aerohead integrates MIPS, the best safety technology there is, which helps disperse rotational impact energy and prevent the cyclist from headbutting the ground. 

To further optimise the safety of the cyclist, a layer of EPS foam is installed in-between the two shells and the interior liner. It helps absorb any shock from the impact.

Size and Fit

The Giro Aerohead MIPS bike helmet is available in three standard sizes: small, medium and large. It comfortably fits head sizes between 51cm and 63cm. With good adjustment, it might as well have room to fit a head size of 65cm.

The Roc Loc Air fit system, a company-exclusive patented technology, allows vertical positioning of the helmet to reduce tension on the head and adjust the height of the helmet.

Also, a micro-dial is situated at the back of the helmet that horizontally adjusts the helmet in small increments and ensures it doesn’t fly off in the wind.


Besides the speed of the helmet, the best feature of the Giro Aerohead MIPS is its addition of a clear and mirrored Zeiss lens. It is quite large in size, unlike visors of other helmets in competition, and provides an unobstructed view of the front and the peripheral side.

Also, it is magnetic instead of bolted so adjusting the visor up and down is easy, does not get rusty as time goes on and reduces wind drag to a minimum. 

Not to mention, cyclist’s eyes are shielded from flyaway debris and dust which at high speeds is almost mandatory to ensure safety.


The Giro Aerohead MIPS bike helmet is composed of four large wind-tunnel intake and exhaust vents that direct airflow inside the helmet to the scalp and back out from the back after cooling down the neck.

An overbrow port is also present to ensure sweat doesn’t run down the face. The ventilation of the helmet is optimised for triathletes and time trialists i.e works best when the cyclist is in a face-forward position. 

The Roc Loc Air Fit system also positions the helmet slightly above the cyclist’s head so airflow to the head is maintained at a steady speed.

Retention System

The Giro Aerohead MIPS bike helmet is secured on top of the head through a combination of the rear adjustment dial, the Roc Loc fit system and the smooth faux leather chin strap that buckles easily, does not interfere with stubble or is saturated with sweat.


The Giro Aerohead MIPS bike helmet weighs 0.99 lbs which is considered to be heavyweight in the low-profile style of helmets. However, with the excellent fitting system installed and the rounded shape of the helmet, the weight is distributed evenly so it feels lighter at high speeds.

Comfort Level

The Giro Aerohead MIPS is exceptionally comfortable to wear on the road daily, while speeding at time trials or competing in a triathlon. The better the riding position is optimised, the greater the ventilation will be at high speeds.

Performance Limitation

Though Giro has definitely equipped the Aerohead MIPS with the best features that function well at time trials, races and off-road riding, it is limited by its division of aerodynamics and ventilation.

The Aerohead MIPS is designed to work best in the lean-forward position which is perfect for time trial cyclists but for efficient ventilation, the wearer must be facing forward to feel a steady stream of air. 

If they face down and look forward, the Giro Aerohead MIPS reduces wind drag i.e performs well aerodynamically but fails to ventilate the rider.


The Giro Aerohead MIPS costs $299 and that is decent for a bike helmet that is optimised for speed, wattage efficiency and has magnetic visors built-in.
