## Summary description

GIRO Aerohead MIPS is a 2026 time trial helmet designed for aerodynamic performance and head protection. This size M (55–59 cm) Matte White version features MIPS technology for rotational-impact reduction and an aero-optimized shell for reduced drag. Intended for competitive time trials and triathlon use, it balances ventilation and aerodynamics for high-speed riding.

## Long description

The GIRO Aerohead MIPS time trial helmet (2026) in size M (55–59 cm) and Matte White finish is a purpose-built aerodynamic helmet for competitive time trials and triathlon racing. It combines an aero-optimized outer shell with integrated MIPS rotational-impact protection to reduce the risk of brain injury in certain impacts while maintaining a streamlined profile aimed at minimizing drag at high speeds. The helmet’s design balances ventilation and aerodynamic performance to suit riders who require low air resistance without fully sacrificing cooling.
Advantages
The helmet integrates MIPS technology to address rotational forces during oblique impacts, alongside a contoured, elongated shell that reduces aerodynamic drag. Its size M fit (55–59 cm) and internal fit system provide a secure and adjustable hold for consistent positioning during intense efforts. The Matte White finish offers a neutral reflective surface that is easy to pair with team kits and race clothing. Materials and construction focus on lightweight durability appropriate for time trial demands.
Suitable for
 Road time trials and prologue stages where aerodynamics are critical
 Triathlon racing, especially non-drafting individual time trial segments
 Solo training efforts and high-speed interval sessions on flat to rolling terrain
 Riders seeking a balance between aerodynamic performance and moderate ventilation
When it may not be suitable
This helmet is optimized for time trial and triathlon use where aerodynamics take priority; it may not be the best choice for everyday commuting or casual rides where maximum ventilation, visibility, or multi-directional impact features for urban environments are more important. Riders who prioritize heavy ventilation for long low-speed climbs or frequent stop-and-go riding may prefer a more vented road helmet.
Key specifications
 Intended use: Time trials and triathlon racing
 Size range: Medium fit for head circumference 55–59 cm
 Protective system: Rotational-impact mitigation (MIPS)
 Shell finish: Matte White
 Aerodynamic design: Elongated, aero-optimized outer shell
 Ventilation: Moderate; designed to balance cooling and low drag
 Retention: Adjustable internal fit system for secure positioning
 Weight category: Lightweight construction for competitive use
How to use
Place the helmet on the head so it sits level, covering the forehead without tilting back. Use the internal adjustment system to achieve a snug, secure fit that prevents excessive movement during efforts; straps should form a V beneath each ear and be fastened comfortably under the chin. Before every ride, check that the MIPS liner and retention system are intact and that the helmet shows no signs of damage. Replace the helmet after any crash or if signs of significant impact or material degradation are present.
What to consider before purchase
 Confirm head circumference falls within the 55–59 cm size range for proper fit
 Assess whether aerodynamic performance is a priority over maximum ventilation
 Consider compatibility with race equipment such as aero bars and eyewear
 Check weight expectations if minimal mass is essential for your setup
Usage recommendations
For best aerodynamic gains, pair the Aerohead MIPS with a riding position optimized for a low torso angle and with properly fitted eyewear. Keep the helmet clean and free of debris; avoid using solvents on the lining or shell. Replace the helmet following any significant impact even if visible damage is minimal, and follow manufacturer guidelines for fit checks and service intervals.
