Bike Helmet GIRO FIXTURE II W — Unisex MTB helmet, Universal size 50–57 cm, Matte White/Chrome

GIRO FIXTURE II W — Unisex MTB helmet in Matte White/Chrome, designed to fit head circumferences from 50 to 57 cm. This helmet combines a multi-ventilation shell with an adjustable fit system and secure retention to provide protective coverage for trail and urban mountain biking. The design balances airflow and coverage to reduce heat build-up while maintaining protection across the forehead, temples and rear head.

Advantages

The helmet offers a universal size fit that accommodates a range of head sizes with a precise micro-adjustable rear retention. Multiple vents channel air through the shell for improved cooling during sustained rides. The shell profile extends coverage at the occipital area for increased protection on technical trails. A removable visor and compatible strap system allow simple adjustments for different riding styles and accessories.

Suitable for

• Recreational mountain biking and trail riding
• Urban commuter cycling requiring reliable impact protection
• All-day rides where ventilation and fit adjustability are important
• Riders seeking a neutral, unisex design and a single universal size

When it may not be suitable

This helmet is designed for standard cycling impact conditions and is not intended for motorized sports, downhill racing with extreme high-speed impacts, or activities that require full-face protection. Riders requiring a smaller than 50 cm fit or larger than 57 cm will need a different size range.

Key specifications

• Fit range: 50–57 cm head circumference
• Type: Unisex mountain bike (MTB) helmet
• Finish: Matte White with Chrome accents
• Ventilation: Multi-ventilation shell design
• Retention: Adjustable rear fit system with micro-adjustment
• Coverage: Extended rear/head occipital coverage for trail protection
• Visor: Removable/adjustable visor

How to use

Place the helmet squarely on the head so the front rim sits above the eyebrows, then tighten the rear retention system until the helmet feels snug but comfortable. Adjust the side straps to form a Y-shape just below the ears and fasten the chin strap, leaving enough room to fit one or two fingers between the strap and the chin. Use the removable visor as needed for sun or debris protection. Inspect the shell, straps and retention mechanism periodically and replace the helmet after any significant impact.

What to consider before purchase

• Measure head circumference to confirm 50–57 cm range fits correctly
• Consider helmet coverage needs: extended occipital coverage vs. full-face protection
• Assess ventilation requirements for typical ride durations and climates
• Check compatibility with accessories such as lights, goggles and communication mounts

Usage recommendations

For optimal protection and comfort, adjust the retention system before each ride, keep vents free of obstructions, and replace the helmet after any crash or visible damage. Use the visor in bright or dusty conditions and pair the helmet with properly fitting eyewear and an appropriate cycling saddle and gloves for improved ride control.
