## Summary description

GIRO AEROHEAD MIPS (NEW 2026) is a time trial aerodynamic cycling helmet featuring MIPS technology for rotational impact protection. This size S shell fits head circumferences 51–55 cm and is finished in Matte White. Designed for racing and triathlon use, it reduces drag while offering enhanced safety and secure fit for high-speed efforts.

## Long description

The GIRO AEROHEAD MIPS (NEW 2026) Size S (51–55 cm) Matte White is an aerodynamic time trial helmet engineered for racing and triathlon events. It combines a low-drag shell profile with integrated rotational impact protection to address both speed and safety. The Size S shell is designed to fit head circumferences from 51 to 55 cm and the Matte White finish provides a neutral, race-oriented appearance.
Advantages
The helmet reduces aerodynamic drag through a contoured shell shape and smooth surface, helping riders maintain higher speeds in time trials and triathlon bike legs. Integrated MIPS technology offers added protection against rotational forces during oblique impacts, while internal fit systems keep the helmet stable and correctly positioned during high-effort efforts. Ventilation and internal padding are balanced to provide comfort without compromising the aerodynamic profile.
Suitable for
Time trial cycling races and individual pursuit events
Triathlon bike legs where aerodynamic efficiency matters
Competitive cyclists seeking a compact, race-focused helmet
Riders with head circumference between 51 and 55 cm
When it may not be suitable
This helmet is optimized for aerodynamic performance and may be less suitable for riders who prioritize maximum ventilation on long, hot training rides. It is also focused on race use rather than casual commuting or urban cycling where multi-directional visibility and frequent on/off use are more important. Riders needing sizes outside the 51–55 cm range should consider other shell sizes.
Key specifications
Intended use: time trial and triathlon racing
Fit range: 51–55 cm head circumference
Shell finish: matte white
Impact protection: rotational protection system integrated
Fit system: adjustable internal retention for secure positioning
Ventilation: low-drag airflow design balancing cooling and aerodynamics
How to use
Place the helmet on the head so that the front edge sits just above the eyebrows and adjust the internal retention system until the helmet feels secure but comfortable. Fasten and adjust the chin strap so it sits snugly under the jaw, leaving enough room to fit one or two fingers between strap and chin. For time trial starts and bike transitions in triathlon, ensure the helmet is securely fastened before mounting the bike and re-check strap tension during warm-up. Replace the helmet after any significant impact or when fit components show wear.
What to consider before purchase
Confirm head circumference falls within 51–55 cm for Size S
Consider whether aerodynamic performance or ventilation is a higher priority for your typical rides
Check compatibility with any race-specific equipment such as aero bars, eyewear, or helmet-mounted hydration systems
Usage recommendations
For best aerodynamic results, pair the helmet with a clean, fitted kit and maintain a steady, aero position on the bike. Regularly inspect fit straps and padding, and replace the helmet after a crash or if structural damage is suspected.
