2. Safety Information
Your Giro Montaro MIPS II helmet is engineered to reduce the risk of head injury in certain impacts. However, no helmet can protect against all possible impacts. Always ride within your limits and wear appropriate safety gear.
MIPS Technology
This helmet incorporates the Multi-Directional Impact Protection System (MIPS). MIPS is a low-friction layer designed to reduce rotational forces that can result from certain impacts. This layer allows a small relative motion between the helmet and the head in an angled impact, aiming to redirect energy and forces that would otherwise be transmitted to the head.

Helmet Replacement
- After an Impact: A helmet that has sustained an impact should be replaced immediately, even if there is no visible damage. The protective materials may be compromised.
- Age: Helmets should be replaced every three to five years, depending on usage and exposure to elements, as materials can degrade over time.
Warnings
- Do not modify or remove any original components of the helmet.
- Avoid exposing the helmet to extreme heat (e.g., inside a hot car), as this can damage the EPS liner.
- Always secure the chin strap properly before riding.

4. Setup: Fitting the Helmet
Proper fit is crucial for helmet safety and comfort. Follow these steps to ensure your Montaro MIPS II helmet fits correctly:
4.1. Adjusting the Roc Loc 5 Air MIPS Fit System
- Place the helmet on your head. It should sit level and cover your forehead.
- Locate the Roc Loc 5 Air dial at the back of the helmet.
- Turn the dial clockwise to tighten the fit system, or counter-clockwise to loosen it, until the helmet feels snug and secure without being uncomfortably tight. The helmet should not move excessively when you shake your head.

4.2. Adjusting the Chin Straps
- Buckle the chin strap.
- Adjust the sliders on the straps so that they form a 'V' shape just below your ears.
- Tighten the chin strap until it is snug under your chin. You should be able to open your mouth wide, but the strap should not be loose enough to allow the helmet to shift significantly.
4.3. Adjusting the P.O.V. Plus Visor
The Montaro MIPS II features an adjustable P.O.V. Plus visor. This visor can be moved up or down to accommodate goggles or to adjust for sun glare.
- Gently push or pull the visor to the desired position. It will click into place at various detents.
- Ensure the visor is securely in position before riding.

Wearing the Helmet
- The helmet should sit level on your head, with the front edge approximately one inch above your eyebrows.
- The chin strap should be comfortably snug, and the side straps should meet just below your ears.
Ventilation
The Montaro MIPS II features 16 Wind Tunnel vents with internal channeling to provide airflow and keep your head cool during rides.
6. Maintenance
Regular care will extend the life and effectiveness of your helmet.
Cleaning
- Clean the helmet shell and pads with a soft cloth, mild soap, and cool water.

Storage

- If any damage is found, replace the helmet immediately.
7. Troubleshooting
If you encounter issues with your helmet, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
