The integrated SELFIT™ 5‑step adjustment enables precise sizing and quick on‑the‑go changes for a consistent fit. Four ventilation openings allow basic airflow for urban and recreational cycling without adding complexity. The buckle clasp secures the helmet simply and reliably, and the compact size S fits head circumferences from 51 to 56 cm.

Check fit and buckle security before each use.

Usage recommendations

Use this helmet for everyday cycling, commuting, and recreational rides. Replace the helmet after any significant impact and follow local regulations on protective headgear. Regularly inspect the shell, straps, and fit system for signs of wear or damage and ensure the size S (51–56 cm) matches the rider's head circumference before purchase.
