## Long description

GIRO Radix Red Size S (51–55 cm) is a lightweight MTB helmet designed for mountain biking, trail riding and daily commuting. The helmet combines multiple ventilation channels with an off-road shell shape to provide impact protection while maintaining airflow and a compact fit. An adjustable retention system allows precise sizing for head circumferences from 51 to 55 cm, making this model suitable for smaller adult and youth riders seeking reliable protection on varied terrain.
Advantages
The Radix helmet offers a balance of protection and ventilation through its engineered shell and internal channels, reducing heat buildup on long rides. The adjustable retention system ensures a snug, stable fit and improves comfort over extended use. The helmet’s off-road design provides rear and side coverage adapted for trail impacts, while the lightweight construction minimizes fatigue during aggressive or all-day rides.
Suitable for
 Mountain biking on singletrack and technical trails
 Trail and enduro training where ventilation and coverage are needed
 Urban commuting and mixed-surface rides
 Recreational cyclists and beginners seeking dependable protection
Key specifications
 Fit range: 51–55 cm head circumference (Size S)
 Construction: hard outer shell with impact-absorbing liner
 Ventilation: multiple internal channels for airflow
 Retention: adjustable rear fit system for precise sizing
 Weight: lightweight design for reduced neck fatigue (typical for this class)
 Coverage: extended rear and side profile for off-road protection
How to use
Place the helmet level on the head so the front edge sits just above the eyebrows. Adjust the rear retention dial until the helmet feels snug but comfortable, then use the side straps to form a V-shape under each ear and fasten the buckle beneath the chin. Tighten the chin strap so two fingers fit between the strap and your chin. Before each ride, check that the helmet is secure and that vents are clear of debris. Replace the helmet after a significant impact or if the fit and integrity appear compromised.
Usage recommendations
Use this helmet for trail, mountain and commuter riding where a balance of ventilation, fit adjustability and extended coverage is required. Ensure correct sizing by measuring head circumference and maintain the retention system and straps in good condition; avoid using helmets past their recommended service life or after major impacts.
