## Long description

The GIRO Radix Integrated MIPS — size S (51–55 cm), Matte Dark Shark Dune is a trail and enduro mountain bike helmet designed to provide reliable impact protection and a secure fit for riders with a 51–55 cm head circumference. This model integrates MIPS technology to address rotational forces during certain impacts, combines an adjustable retention system for a tailored fit, and offers ventilation channels suited to active riding. The shell and internal liner are configured to balance protection, comfort and compatibility with goggles and eyewear.
Advantages
The helmet features Integrated MIPS technology to reduce rotational motion transferred to the head in some impacts, while its size S fit and adjustable retention system allow for secure, customizable positioning. Ventilation and internal shaping promote airflow and comfort during sustained effort, and the helmet’s profile is compatible with goggles and most eyewear. Construction focuses on durable shell materials and an impact-absorbing liner to meet the needs of trail and enduro riding.
Suitable for
 Trail riding and enduro courses where balanced protection and ventilation are required
 Riders with head circumference 51–55 cm seeking an adjustable, secure fit

 Retention: adjustable dial-fit retention system for micro-adjustments
 Ventilation: multiple vents and internal channels for airflow

How to use
Place the helmet on the head so the front edge sits just above the eyebrows and the rear shell covers the back of the head without tilting. Adjust the dial-fit retention system until the helmet feels snug but comfortable, and position the side straps to form a V-shape under the ears. Fasten the chin strap and tighten it so that one or two fingers fit between the chin and the strap. Verify that goggles or eyewear fit comfortably with the helmet and that ventilation channels are unobstructed. Replace the helmet if it sustains a significant impact or shows visible damage.
Usage recommendations
Choose the size S (51–55 cm) for a secure fit and routinely check retention and strap adjustment before each ride. For optimal protection, follow manufacturer guidance for helmet lifespan and replacement after strong impacts.
