Material: injection-molded plastic
Function: stepwise tightening and loosening of helmet retention
Compatibility: designed for helmets using the Giro Tyrant fit system
How to use
Remove the damaged or existing dial by releasing any retention clips or screws that secure it to the Tyrant retention mechanism, following the helmet manufacturer's disassembly guidance. Align the replacement dial with the retention unit and press or fasten it into place until the attachment points engage. Verify that the dial rotates smoothly and that each click provides incremental tightening or loosening.

Inspect the fit system after installation and periodically during use. Avoid over-torquing or forcing the dial beyond its normal click range. If any cracks, excessive play, or malfunction are detected, discontinue use and replace the component or consult an authorized service provider.
