2. Safety Information
Your safety is paramount. Always wear your helmet correctly and ensure it is properly fitted before every ride. This helmet is designed to reduce the risk of head injury in certain types of impacts, but it cannot protect against all possible impacts. No helmet can protect the wearer from all foreseeable impacts.
- Proper Fit: Ensure the helmet fits snugly and comfortably. It should not move freely on your head. Refer to the "Fitting Your Helmet" section for detailed instructions.
- Strap Adjustment: Always secure the chin strap tightly so that the helmet cannot be pulled off your head.
- Impact Protection: The MIPS system is designed to reduce rotational forces that can result from certain angled impacts. However, it does not guarantee protection against all types of impacts.
- Damage: Inspect your helmet for any signs of damage before each use. If the helmet has sustained an impact, even if no visible damage is present, it should be replaced immediately. The structural integrity may be compromised.
- Chemicals: Do not expose the helmet to solvents, paints, or other chemicals, as these can damage the helmet's materials and compromise its protective capabilities.
- Storage: Store the helmet in a cool, dry place away from direct sunlight and extreme temperatures.

4. Setup and Fitting Your Helmet
Achieving a correct fit is crucial for the helmet's effectiveness.
4.1. Sizing
Measure your head circumference approximately 2.5 cm (1 inch) above your eyebrows. Compare this measurement to the sizing chart below to select the appropriate helmet size. If your measurement falls between two sizes, it is generally recommended to try the smaller size first for a snugger fit.
| Brand Size | Head Circumference (CM) | Head Circumference (IN) |
|---|---|---|
| XS | 50 - 54 | 19.7 - 21.2 |
| S | 52 - 56 | 20 1/2 - 22 |
| M | 55 - 59 | 21 2/3 - 23 2/9 |
| L | 58 - 61 | 22 5/6 - 24 |
| XL | 61 - 64 | 24 - 25 1/5 |
| Unisize | 54 - 61 | 21 1/4 - 24 |
4.2. Adjusting the Fit
- Position the Helmet: Place the helmet squarely on your head so that the front edge is approximately 2.5 cm (1 inch) above your eyebrows. It should sit level, not tilted back or forward.
- Adjust the ARS Fit System: The LAZER G1 MIPS features the Advanced Rollsys System (ARS). Locate the dial on the top of the helmet. Turn the dial clockwise to tighten the fit system, drawing the helmet snugly around your head. Turn counter-clockwise to loosen. Adjust until the helmet feels secure without causing uncomfortable pressure points.
- Adjust the Straps: The side straps should form a "V" shape just below your ears. Adjust the strap sliders to ensure this position.
- Secure the Buckle: Fasten the chin strap buckle. Tighten the 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.
- Check the Fit: Once adjusted, try to move the helmet from side to side and front to back. It should feel snug and move your scalp slightly. If it slides easily, readjust the ARS system and straps.

5. Operating Your Helmet
The LAZER G1 MIPS helmet is designed for straightforward use once properly fitted.
5.1. Ventilation
The G1 MIPS helmet features 22 strategically placed vents and internal air channels to maximize airflow and keep your head cool during rides. No manual adjustment is required for the ventilation system; it operates passively.

5.2. MIPS Technology
The integrated MIPS (Multi-Directional Impact Protection System) is a low-friction layer inside the helmet designed to reduce rotational motion transferred to the brain from angled impacts. This system works automatically upon impact and requires no user interaction.
5.3. Riding with the Helmet
Always wear your helmet when cycling. Ensure the fit is secure and comfortable before beginning your ride. The lightweight design and advanced fit system are intended to provide comfort even on long rides.

6. Maintenance and Care
Proper care will extend the life of your helmet and maintain its protective qualities.
- Cleaning the Helmet: Use only mild soap and water to clean the helmet's exterior and interior padding. Do not use harsh chemicals, abrasive cleaners, or solvents, as these can damage the helmet's materials, including the shell, EPS foam, and MIPS layer.
- Cleaning Pads: The internal padding can be removed and hand-washed with mild soap and water. Allow pads to air dry completely before reinserting them into the helmet.
- Storage: Store your helmet in a cool, dry place, away from direct sunlight and extreme temperatures. Avoid storing it in a car on a hot day, as excessive heat can damage the EPS foam.
- Inspection: Regularly inspect the helmet for any signs of wear, cracks, dents, or other damage to the shell, straps, buckle, or fit system. If any damage is found, the helmet should be replaced.
7. Troubleshooting
This section addresses common issues you might encounter.
| Problem | Possible Cause | Solution |
|---|---|---|
| Helmet feels loose or shifts on head. | Improper adjustment of ARS system or straps. | Tighten the ARS dial (top of helmet) clockwise. Ensure chin strap is snug and side straps form a "V" below ears. Refer to Section 4.2. |
| Helmet is uncomfortable or causes pressure points. | Helmet size may be incorrect or ARS system is too tight. | Loosen the ARS dial slightly. Check if the helmet size is appropriate for your head circumference (Section 4.1). Consider using alternative padding if available. |
| Straps are twisted or difficult to adjust. | Straps may have been incorrectly threaded or stored. | Unbuckle and unthread straps completely. Re-thread them ensuring they lie flat and are not twisted. Adjust sliders as needed. |
| Visible damage to helmet after an impact. | Helmet has absorbed an impact. | Immediately replace the helmet. Even minor visible damage can indicate compromised protective integrity. Do not use a damaged helmet. |
