Product information

Description

Replacement adjustment dial designed for GIRO helmets that use the ROC LOC DH retention system and compatible with size M and L helmets from the 2017 model range. This replacement part restores the helmet’s fit-control mechanism, allowing riders to fine-tune tightness and lateral stability. The dial is a direct-fit component intended to work with Giro’s ROC LOC DH interface to maintain a consistent and adjustable fit during cycling and downhill riding.

Advantages

The adjustment dial provides precise micro-adjustment of helmet circumference, enabling an improved and repeatable fit without changing the shell or foam liner. It replaces worn or damaged knobs to recover original retention performance and preserves the helmet’s designed comfort and stability. The part is compatible with the ROC LOC DH interface and supports safe, tool-free on-the-fly tightening and loosening.

Suitable for

  • Replacement for Giro ROC LOC DH helmets in sizes M and L (2017 models)
  • Downhill and trail riding where secure helmet fit is essential
  • Regular cyclists needing to restore a worn retention dial

Key specifications

  • Compatibility: ROC LOC DH retention system for Giro helmets (size M & L, 2017 models)
  • Function: micro-adjustment dial for helmet circumference and fit tension
  • Mounting type: direct replacement for the OEM ROC LOC DH knob
  • Material properties: durable polymer construction designed for repeated adjustment
  • Operation: tool-free turning mechanism for on-the-ride fit changes

How to use

Fit the replacement dial onto the ROC LOC DH retention interface following the helmet manufacturer’s instructions for removal of the old dial. Once installed, rotate the dial clockwise to tighten the fit and counterclockwise to loosen. Verify even seating of the retention band and perform a fit check to confirm the helmet sits snugly and securely on the head before riding. If any resistance or misalignment is detected during installation, inspect the retention cradle and straps for damage and consult Giro documentation or an authorized dealer.

Usage recommendations

Use this replacement dial only with Giro helmets specified to use the ROC LOC DH interface and sizes M or L from the compatible model year. Periodically check the dial and retention system for wear and ensure straps and attachment points are intact. Replace the component if it shows cracks, severe wear, or fails to hold adjustment reliably.
