## Long description

The Giro Adjustment Dial for Radix Fit System is a replacement retention component designed to restore the fit and micro-adjustment functionality of compatible Giro Radix helmets. Finished in black and sized XL, this OEM Giro part replaces a worn or damaged dial to re-enable precise, incremental tightening and loosening of the helmet retention system for a secure, comfortable wear during cycling and other helmeted activities.
Advantages
This Giro replacement dial provides exact micro-adjustment via a simple rotary mechanism, allowing the user to fine-tune helmet fit quickly and precisely. Being an OEM component, it matches the original fit system geometry and materials, ensuring compatibility and maintaining the helmet’s intended retention performance. The XL size offers a larger engagement surface for users who require extended adjustment range or prefer a larger dial for easier operation while on the move.
Suitable for
Giro Radix helmets that use the Giro Radix Fit System
Cyclists seeking to replace a broken or worn adjustment dial
Users needing more precise micro-adjustments for comfort and stability
Key specifications
Brand: Giro (OEM replacement part)
Fit system compatibility: Giro Radix Fit System
Color: Black
Size: XL (larger dial engagement for extended adjustment range)
Function: Rotary micro-adjustment dial for helmet retention
How to use
To install, remove the damaged or worn dial from the helmet’s Radix Fit System housing and align the replacement dial with the retention interface according to the helmet manufacturer’s guidance. Press or snap the dial into place until it engages securely with the internal ratchet or spool mechanism. Rotate the dial clockwise to tighten and counterclockwise to loosen the retention loop, adjusting incrementally until the helmet sits comfortably and securely on the head. Ensure the dial is fully engaged and test adjustment range before use.
Usage recommendations
Inspect the fit system regularly for wear or damage and replace the dial if teeth, clips, or engagement features are compromised. Use the XL dial when a larger control surface or extended adjustment range is needed. After installation, confirm correct operation and do not use a helmet with a compromised retention system.
