## Long description

Replacement adjustment dial for GIRO helmets equipped with the ROC LOC CITY 2017 retention system. This spare part restores the micro-adjustment function of the helmet's retention mechanism and re-establishes correct headband tension for a secure, personalized fit.

Advantages
The GIRO ROC LOC CITY 2017 adjustment dial provides precise manual circumference control and smooth operation to fine-tune helmet fit. As an original-fit spare part, it is matched to the geometry and attachment points of the corresponding retention system, ensuring reliable engagement and consistent tension. Installing this dial can extend the service life of the helmet's fit system and restore user comfort while preserving the helmet's intended adjustment range.

Key specifications
Compatibility: ROC LOC CITY 2017 helmet retention systems on GIRO models
Function: manual micro-adjustment of head circumference and band tension
Material: durable polymer construction for repeated adjustment
Mounting: designed to engage the original retention mechanism attachment points
Finish: OEM color and texture to match factory-fit appearance
How to use
Remove the damaged or worn dial from the helmet retention unit following manufacturer guidance, then align and press the replacement dial onto the retention mechanism until it locks into its mounting points. Rotate the dial clockwise or counterclockwise to increase or decrease headband circumference, achieving a snug but comfortable fit. After installation, check that the retention system moves freely and secures the headband evenly around the head.
Usage recommendations
Use the adjustment dial to fine-tune fit before each ride and periodically inspect the retention unit for wear. Avoid excessive force when turning the dial; if the mechanism resists, verify correct seating and compatibility. Replace the dial if cracks, stripped teeth, or compromised engagement are visible to maintain safe and consistent fit adjustment.
