## Long description

Replacement adjustment dial designed specifically for GIRO ARIES SPHERICAL helmets that use the ROC LOC 5 AIR + FIT System. This black size M dial restores the helmet’s micro-adjustment mechanism to provide a consistent, secure hold and improved retention performance. The component is intended as a direct replacement to maintain the original fit tuning and comfort characteristics of the ROC LOC 5 AIR + FIT System in compatible GIRO ARIES SPHERICAL helmets.
Advantages
The adjustment dial enables precise, incremental fit adjustments to achieve stable helmet positioning without excessive pressure points. As a purpose-made spare part for the ROC LOC 5 AIR + FIT System, it preserves the system’s ventilation pathways and heel retention geometry while restoring the original adjustment range. The black finish matches the helmet’s aesthetic and the size M specification ensures compatibility with medium-sized retention assemblies.
Suitable for
Restoring fit and retention on GIRO ARIES SPHERICAL helmets equipped with ROC LOC 5 AIR + FIT System
Replacing a damaged or worn adjustment dial to recover micro-adjustment functionality
Maintaining consistent fit for commuting, recreational cycling, and trail rides where an accurate helmet fit is required
Key specifications
Compatibility: designed for helmets using the ROC LOC 5 AIR + FIT retention system
Size: M — intended for medium retention assemblies
Color: black finish to match helmet styling

How to use
Remove the helmet pads if needed and access the retention system at the rear of the helmet. Release and remove the existing dial according to the helmet manufacturer’s instructions, then align the replacement dial with the retention assembly and press or secure it into place until it clicks or seats firmly. Test the adjustment by turning the dial to tighten and loosen the fit, confirming smooth operation and secure engagement before use. Reinstall any helmet pads removed during the procedure.
Usage recommendations
Inspect the retention system periodically for wear and correct engagement. Replace the dial if you notice cracking, excessive play, or impaired adjustment function. Use only the specified size and compatible ROC LOC 5 AIR + FIT components to maintain helmet safety and intended fit characteristics.
