Take your cycling and triathlon performance to the next level with the Giro Aerohead™ Road Cycling Helmet with MIPS® – the ultimate helmet for time-trialists, triathletes, and competitive road cyclists. Developed in the wind tunnel, tested on the track, and proven in Tour de France and Ironman World Championship races, this aero helmet delivers maximum speed, aerodynamics, and cooling without sacrificing safety or comfort.


Integrated MIPS® Brain Protection System – Giro’s Multi-directional Impact Protection System (MIPS®) helps reduce rotational forces during angled impacts, providing enhanced head protection while exceeding strict cycling safety standards. Ideal for triathlons, time trials, and road racing.

Aerodynamic Wind Tunnel Design – Engineered for superior aerodynamics, the Aerohead helmet uses a sleek, elongated profile to reduce drag. Giro’s proprietary Wind Tunnel™ ventilation system channels airflow across your head and exhausts heat efficiently, keeping you cool during long rides, hot races, and intense sprints.

Wrap-Around ZEISS® Optics Eye Shield – The integrated magnetic eye shield provides unobstructed vision and razor-sharp clarity for road racing or triathlon competition. Easily removable and flip-up capable for quick transitions during bike splits or changing conditions.

Roc Loc® 5 Air Fit System – Fine-tune your helmet fit with Giro’s micro-adjustable Roc Loc® 5 dial, allowing independent vertical positioning and dialed contact points for a customized, secure fit. This ensures stability and comfort at high speeds.

Super Fit™ Engineering – Based on over 25 years of human-scale helmet design, the Super Fit™ sizing system offers precise fit across multiple adult sizes for a helmet that feels custom-made.

Durable In-Mould Hardbody™ Shell – The two-piece polycarbonate hard shell fused to the EPS liner provides lightweight, durable protection while maintaining superior aerodynamics.

Ionic+® Antimicrobial Padding – IONIC+® silver-infused padding offers permanent odour protection to keep your helmet fresh during long training sessions or multi-day events.


Whether you’re training for a triathlon, racing a time trial, or pushing for a podium finish, the Giro Aerohead Road Cycling Helmet with MIPS® delivers elite aerodynamics, top-tier ventilation, and MIPS-protected safety for cyclists who demand speed, comfort, and performance.

Bike Helmet Size Guide

How to measure your size – Wrap a measuring tape around your head, keeping the tape level from front to back. Note the measurement and reference the Size Guide. Note: Make sure the helmet fits with a little room when the fit system is loose, and sits low enough to protect your forehead without hindering your vision. Once you’ve got the right size, you can adjust the fit.

For helmets equipped with MIPS technology, please review the following warning: SOME MIPS® LOW-FRICTION LAYERS, ALONG WITH OTHER PARTS OF A HELMET, MIGHT CAUSE LACERATIONS TO THE WEARER’S HEAD/FACE IN SOME ACCIDENTS. THIS MIGHT OCCUR DUE TO THE HIGH PRESSURE ON THE SCALP FROM THE IMPACT OR AS A BY-PRODUCT OF THE LOW-FRICTION LAYER’S MOVEMENT IN CERTAIN ANGLED IMPACTS TO HELP REDUCE THE ROTATIONAL ENERGIES TO THE HEAD. IF YOU WOULD LIKE FURTHER INFORMATION, PLEASE CONTACT US.
