## Long description

GIRO Radix MTB black size S (51–55 cm) is a protective cycling helmet designed for mountain biking and trail riding. The helmet features a vented shell design that promotes airflow, an adjustable fit system for secure positioning on small head sizes, and a lightweight construction that balances protection with comfort. This model is intended to reduce the risk of head injury during recreational and off-road cycling while maintaining breathability and fit control for active riders.
Advantages
The vented shell improves ventilation to help regulate temperature during physical effort, while the lightweight materials reduce neck strain on longer rides. The adjustable fit system allows fine-tuning for sizes within the 51–55 cm range, ensuring stable positioning and consistent coverage. The helmet’s design integrates protection and comfort to meet the needs of trail and cross-country cyclists seeking reliable head protection without excessive bulk.
Suitable for
 Mountain biking on trails and singletrack
 Cross-country cycling and endurance rides

Key specifications
 Size range: Small, fits head circumference approximately 51–55 cm
 Color: Black
 Construction: Lightweight vented shell for airflow
 Fit system: Adjustable retention for secure, personalized fit
 Intended use: Mountain bike and off-road cycling
How to use
Place the helmet on the head so it sits level and covers the forehead without tilting back. Adjust the retention system until the helmet feels snug but comfortable, then fasten and adjust the chin strap so it sits under the jaw with one or two fingers of space between strap and chin. Before each ride, check that the helmet is securely fastened, that straps and buckles are undamaged, and that the helmet shows no visible cracks or significant damage. Replace the helmet after any substantial impact or when fit and structural integrity are compromised.
Usage recommendations
Use the helmet for trail and cross-country rides where ventilation and a lightweight fit are priorities. Regularly clean the interior padding and straps with mild soap and water, avoid strong solvents, and store the helmet away from direct sunlight and high heat to preserve materials and fit performance.
