## Summary description

GIRO RADIX MIPS is a protective mountain bike helmet featuring MIPS technology and a size S fit for head circumferences 51–55 cm. Finished in matte stone, this 2026 model provides impact protection for trail and cross-country riding, with an adjustable retention system and ventilation for everyday MTB use and recreational cycling.

## Long description

The GIRO RADIX MIPS — size S (51–55 cm), matte stone, model 2026 is a protective mountain bike helmet designed for trail and cross-country riders who require a secure fit and rotational-impact protection. This helmet integrates MIPS technology with an adjustable retention system and a vented shell to balance protection, fit, and airflow for everyday MTB use and recreational cycling.
Advantages
The helmet provides rotational-impact mitigation through MIPS, while the adjustable fit system ensures consistent positioning on head sizes from 51 to 55 cm. A matte stone finish offers a low-glare, neutral appearance. Ventilation channels are incorporated to promote airflow during sustained efforts, and the helmet’s construction focuses on a lightweight but protective design suitable for off-road riding.
Suitable for
Trail riding and cross-country (XC) cycling.
Recreational mountain biking and daily off-road training.
Riders with head circumferences of 51–55 cm seeking a size S fit.
Cyclists who prefer a matte, understated helmet finish.
When it may not be suitable
This model is sized for small heads (51–55 cm) and may not accommodate riders requiring larger sizes. It is engineered for trail and XC use; riders who need full-face protection for aggressive downhill or enduro racing should consider helmets specifically designed for those disciplines.
Key specifications
Fit range: 51–55 cm (size S).
Safety system: MIPS (rotational-impact mitigation system).
Finish: matte stone color.
Use case: mountain bike — trail and cross-country.
Ventilation: multiple vents with internal channels for airflow.
Retention: adjustable rear-fit retention mechanism for secure fit.
Construction: lightweight protective shell with impact-absorbing liner.
How to use
Place the helmet level on the head so the front edge sits just above the eyebrows. Adjust the rear-fit retention until the helmet feels snug but comfortable, then fasten and adjust chin straps so two fingers fit between the strap and the chin. Verify that the helmet remains stable during head movement and that vents are unobstructed. Replace the helmet after any significant impact or if structural damage is visible.
What to consider before purchase
Measure head circumference to confirm a 51–55 cm fit range is correct.
Decide whether MIPS rotational protection and a vented trail helmet meet your discipline requirements.
Consider helmet weight and ventilation relative to intended ride duration and terrain.
Check compatibility with accessories (e.g., goggles, lights) if needed.
Usage recommendations
For best protection, replace the helmet after a significant crash, ensure a snug fit each ride, and clean with mild soap and water; avoid solvents or harsh chemicals that could degrade helmet materials.
