## Long description

Replacement fit adjustment dial designed for GIRO helmets that use the Radix Fit System. This black plastic dial in size S attaches to compatible retention systems to restore or improve the helmet’s adjustability, allowing precise control of head circumference for a secure, custom-like fit. The component is intended for repair or upgrade of existing helmets when the original dial is worn, damaged, or when finer adjustment is required.
Advantages
The dial provides straightforward mechanical adjustment with incremental clicks for predictable tension changes and repeatable fit. Made from durable plastic, it is lightweight and corrosion-resistant, helping maintain the original fit system’s performance without adding bulk. Its compact size fits the Radix S retention assembly to preserve helmet balance and comfort while enabling easy replacement during routine maintenance.
Suitable for
Repairing a GIRO helmet equipped with the Radix Fit System

Upgrading a helmet to regain finer head circumference control
Key specifications
Compatibility: fits GIRO helmets using the Radix Fit System (size S retention assembly)
Material: molded plastic construction for lightweight durability
Color: black
Size: small (S) — designed for S-size retention components
Adjustment mechanism: stepped dial with tactile click increments for precise tensioning
How to use
To install, remove the helmet’s existing dial or retention assembly cover following the helmet manufacturer’s guidance, align the replacement dial with the Radix retention mounting points and press or snap it into place until it secures. Turn the dial clockwise to tighten and counterclockwise to loosen, adjusting until the helmet sits snugly and evenly on the head. After installation, perform a fit check and brief wear test to confirm the dial functions correctly and that the helmet remains comfortable and stable during head movement.
Usage recommendations
Use only with helmets specified by the manufacturer as compatible with the Radix Fit System. Inspect the retention assembly and surrounding helmet shell before and after replacement; replace any cracked or compromised components. If unsure about installation, consult an authorized service center or follow official GIRO instructions to ensure safe and correct fitting.
