FAQs

What is the difference between MIPS and Spherical MIPS?

Standard MIPS uses a thin slip-plane layer inside the helmet. Spherical MIPS integrates the slip-plane into a ball-and-socket design between two layers of EPS foam, providing a more refined and comprehensive impact management system.

How often should I replace the helmet?

Giro recommends replacing any helmet that has been involved in an impact, even if it looks undamaged. Under normal use, replace your helmet every 3 to 5 years.

Can I wash the pads in a washing machine?

It is highly recommended to hand wash the pads in cold water with mild soap to maintain their shape and anti-microbial properties.

Is the visor adjustable?

Yes, the Merit Spherical features an adjustable visor to help with goggle storage and visibility.

Does this helmet come with a carry bag?

Typically, the helmet does not include a carry bag, but check your specific packaging for included accessories.

Troubleshooting

Dial adjustment feels stiff or sticks.

Check for debris or dirt inside the Roc Loc mechanism and gently clean it with compressed air or a soft brush.

Padding smells after heavy use.

Hand wash the removable Ionic+ liners with mild detergent and allow them to air dry completely.

Helmet shifts during rides.

Re-adjust the tension of the Roc Loc dial and ensure the side strap Y-junctions are positioned correctly below the ears.

Pros and Cons

Pros

  • Superior rotational impact protection through MIPS Spherical technology
  • Excellent airflow and ventilation for hot weather riding
  • Secure and stable fit thanks to the Roc Loc Trail Air system
  • Anti-microbial padding helps maintain hygiene and freshness

Cons

  • Higher price point compared to standard non-spherical helmets
  • Specific fit profile may not suit every head shape
  • Advanced technical features require slightly more care during maintenance

Setup, Compatibility & Care

To ensure maximum safety and comfort, start by loosening the Roc Loc dial before placing the helmet on your head. Once positioned level on your forehead, tighten the rear dial until snug but comfortable. Adjust the side straps so the Y-junction sits just below your ears, and ensure the chin strap is tightened to allow only one or two fingers of space. For care, remove the Ionic+ padding periodically to hand wash it in mild soap and water. Clean the exterior shell with a damp cloth; avoid harsh chemicals or solvents that could compromise the integrity of the polycarbonate shell or EPS foam liner. Always store the helmet in a cool, dry place away from direct sunlight.
