Spare Parts for GIRO ROC LOC 5 LED helmet retention system, model GR-35374-001-OS

Replacement spare parts for the GIRO ROC LOC 5 LED helmet retention system provide components to restore fit, rear retention, and the adjustment mechanism of compatible Giro helmets. These parts are intended for helmets that use the ROC LOC 5 LED retention platform and are designed to maintain or recover the original performance of the fit system, including the wheel adjustment and the LED-compatible rear housing.

Advantages

These spare parts let you replace worn or damaged elements of the ROC LOC 5 LED mechanism without needing a full helmet replacement. They support precise micro-adjustment via the retention wheel, preserve rear cradle stability for consistent fit, and maintain compatibility with LED modules where the helmet design includes integrated lighting. Using original-design components helps keep the adjustment action smooth and predictable, and can extend the service life of the helmet’s fit system.

Suitable for

• Repairing or refurbishing Giro helmets that employ the ROC LOC 5 LED retention system
• Replacing worn adjustment wheels, rear cradles, or LED-compatible housings
• Maintenance and fit customization to restore original fit and comfort

When it may not be suitable

These spare parts are specific to the ROC LOC 5 LED retention platform and will not fit helmets that use different retention systems or older/newer variants with incompatible mounting geometry. They are intended for users who have compatible Giro helmets and need replacement components; they are not a substitute for a damaged helmet shell or situations where the helmet has suffered structural impact.

Key specifications

• Function: replacement components for helmet retention and fit adjustment
• Compatibility: designed for helmets that use the ROC LOC 5 LED retention platform
• Includes: components for rear retention/cradle, adjustment wheel interface, and LED-compatible housing areas (as applicable)
• Material characteristics: durable molded plastic components intended for mechanical adjustment use
• Mounting: designed to interface with the original retention mounting points used by the ROC LOC 5 LED system

How to use

Identify the worn or damaged element of the ROC LOC 5 LED system on your Giro helmet and remove the old component according to the helmet manufacturer’s service guidance. Fit the replacement piece into the original mounting points, ensuring the adjustment wheel and rear cradle align and rotate freely. If your helmet includes an LED module, verify that the housing and electrical contacts (if present) are correctly seated and functioning. Reassemble any straps or covers and test the retention adjustment for smooth, secure operation before use.

What to consider before purchase

• Confirm that your helmet uses the ROC LOC 5 LED retention system and that mounting geometry matches these parts
• Spare parts replace adjustment and retention components only; they do not repair damage to the helmet shell
• Check whether your helmet’s LED module (if present) requires separate replacement or electrical connectors

Usage recommendations

Follow the manufacturer’s service instructions when replacing parts and inspect the helmet for structural damage after any crash. Regularly check retention components for wear and proper operation, and perform replacement if adjustment action becomes stiff, loose, or unreliable.
