## Long description

GIRO Radix is a protective mountain bike helmet in size S (51–55 cm) finished in Matte Harbor Blue. Designed for trail and cross-country riding, the helmet provides coverage for the head with a low-profile shell and integrated ventilation. The shell shape and internal EPS liner are engineered to manage linear impacts typical of everyday mountain biking, park sessions and urban commutes.
Advantages
The helmet combines a compact fit with adjustable retention to ensure stable positioning on small head sizes. Multiple vents promote airflow to help regulate temperature during moderate to intense rides. The matte finish resists glare and provides a durable surface for regular outdoor use. The helmet is lightweight for the size and intended to balance protection with comfort for prolonged wear.
Suitable for
 Trail and cross-country mountain biking
 Bike park and short technical descents
 Daily commuting and urban riding
 Recreational off-road use and fitness rides
Key specifications
 Size range: S (51–55 cm)
 Shell finish: Matte Harbor Blue
 Construction: Hard outer shell with EPS impact liner
 Ventilation: Multiple intake and exhaust vents for airflow
 Fit system: Adjustable retention mechanism for secure fit
 Intended use: Mountain bike / trail / cross-country / commuting
How to use
Place the helmet on the head so the front edge sits just above the eyebrows and center it for even coverage. Adjust the retention system until the helmet feels snug but not tight, then fasten the chin strap and position the side sliders so the straps form a V just below the ears. Tighten the chin strap so it secures the helmet without causing discomfort; you should be able to fit one or two fingers between the strap and your chin. Inspect the helmet before each ride for cracks, damaged foam, or compromised straps and replace the helmet after any significant impact.
Usage recommendations
Use the helmet for its intended activities—trail, cross-country and urban cycling—and replace it every few years or immediately after a crash. Clean the helmet shell with mild soap and water and avoid solvent-based cleaners. Store in a dry place away from direct sunlight and extreme heat to preserve the shell and liner materials.
