Helmet GIRO Switchblade, size M (55–59 cm), black

The GIRO Switchblade in size M (55–59 cm) is a convertible mountain bike helmet that offers a removable chin bar for easy switching between full-face and open-face configurations. The black shell combines impact protection and ventilation to suit trail and enduro riding. An adjustable fit system and a peak visor provide a secure, customizable fit while maintaining airflow for extended rides on technical terrain.

Advantages

The helmet’s modular design allows rapid conversion from full-face protection to a lighter, open-face setup without tools, adapting to changing trail conditions. Its construction balances coverage and ventilation, and the adjustable retention system ensures a stable fit for the stated head circumference. The integrated visor and aerodynamic shape reduce interference from branches and debris while preserving visibility.

Suitable for

• Trail riding where occasional full-face protection is needed
• Enduro stages and aggressive off-road descents
• All-day rides that require both ventilation and impact coverage
• Riders who want a single helmet for both open-face and full-face use

How to use

Place the helmet on the head so it sits level and covers the forehead without tilting back. Adjust the retention dial or straps until the helmet feels snug but comfortable; the helmet should not shift when you move your head. If using full-face protection, attach the chin bar according to the manufacturer’s fitting points until it locks in place; verify that the chin bar is secure before riding. Use the visor adjustment to set the preferred angle for visibility and sun protection. Regularly inspect attachment points and the shell for signs of damage and replace components if wear or impact compromise safety.

Usage recommendations

Choose the full-face configuration for high-speed technical descents or enduro stages and switch to open-face for climbs, transfer sections, or less demanding trails to improve ventilation and hearing. Follow the manufacturer’s maintenance and replacement guidance: replace the helmet after a significant impact or when fit and integrity are compromised. Clean the helmet with mild soap and water and avoid solvents that can weaken shell materials.
