## Summary description

GIRO AEROHEAD MIPS (NEW 2026) is a time trial cycling helmet designed for aerodynamics and protection. This Size S (51–55 cm) Matte Black model features MIPS technology to reduce rotational forces in impacts and is tailored for competitive time trials and fast road efforts. Use it for races, training, and events where aerodynamic performance and head safety are priorities.

## Long description

GIRO AEROHEAD MIPS (NEW 2026) in Size S (51–55 cm), Matte Black is a time trial helmet engineered for aerodynamic performance and impact protection. The helmet integrates MIPS technology to help reduce rotational forces during oblique impacts and is shaped to optimise airflow in solo efforts and short high-speed time trial courses. Its size S fit is intended for head circumferences between 51 and 55 cm and the matte black finish provides a low-profile appearance suited to race and training environments.
Advantages
The helmet offers a combination of aerodynamic shell design and integrated MIPS rotation management to balance speed and safety. Its form reduces drag in time trial positions while maintaining ventilation and comfort for sustained efforts. The construction targets a secure fit for the specified size range, and the matte surface minimises glare from sunlight or track lighting. Materials and internal padding are selected to provide shock absorption, fit adjustability, and rider comfort during racing and intense training sessions.
Suitable for
 Individual time trials and short to medium-distance triathlons
 High-speed road efforts where aerodynamic advantage matters
 Competitive training sessions and paced intervals
 Riders with head circumference of 51–55 cm seeking a dedicated time trial helmet
When it may not be suitable
This helmet is purpose-built for time trials and aerodynamic performance; it may be less suitable for riders who prioritise maximum ventilation for long, hot endurance rides or for those who frequently ride in group road races where multi-directional ventilation and peripheral visibility are more important. If your head circumference falls outside the 51–55 cm range, choose a different size to ensure proper fit and safety.
Key specifications
 Intended use: Time trial / aerodynamic road cycling
 Fit range: 51–55 cm head circumference (Size S)
 Safety feature: MIPS (rotational impact protection system)
 Finish: Matte black
 Shell design: Aerodynamic profile for reduced drag
 Comfort: Internal padding and adjustable retention system for secure fit
How to use
Place the helmet on the head and adjust the retention system until the helmet sits level and snug without excessive pressure. Secure the chin strap and adjust so that it is comfortable and keeps the helmet stable during movement. Ensure internal pads are positioned to eliminate pressure points and that vents and the shell align with your riding posture. Replace the helmet after any significant impact or when the integrity of the shell or retention system is compromised. Follow manufacturer care instructions for cleaning and storage to preserve materials and performance.
What to consider before purchase
 Measure head circumference to confirm 51–55 cm size fits correctly.
 Assess whether aerodynamic design matches your typical riding discipline.
 Consider ventilation needs for your usual ride lengths and temperatures.
 Verify helmet compatibility with accessories (visors, communication units) if required.
Usage recommendations
For optimal aerodynamic benefit, use the helmet in a consistent time trial position and ensure a snug, level fit. Inspect the helmet regularly for wear and replace it after a crash or if structural damage is detected. Combine with appropriate eyewear and clothing to maintain low drag and effective rider protection.
